SpringIntegration
© EInnovator.org
Spring Integration is an integration framework for Java
that support the development of applications based on
the principles of Enterprise Integration Patterns (EIP). It
makes straightforward for applications to integrate with
many types of protocols, systems, and data formats,
using pipelines of out-of-the-box components.
Spring Integration is based on Spring Framework and
support the same kinds of configuration styles, including
XML, annotations, Java DSL, and programmatic use of
the components API. Components are bundled in
different modules, and each module has a dedicated XML
namespace that can be used to configure the
components. A core XML namespace defines the mostly
used component (e.g. router, filter, transformer, service-
activator, etc.), while the integration components come in
dedicated namespaces (e.g. file-system, JMS, AMQP,
FTP(S), HTTP, TCP/UDP/IP, JDBC, GemFire, etc.).
Components can also be defined as Spring beans in
factory methods of Java @Configuration classes, or
using a Java DSL based on the concept of
IntegrationFlow.
In the EIP programming-model components interact by
unidirectional in-memory message passing, rather than
method invocation with return values. Data is exchanged
between endpoint components through communication
channels, with varied semantics. The overall architecture
of the application is a network or pipeline of endpoints
linked by channels (see fig. below).
Components are broadly defined as channels or
endpoints. Both channels and endpoints come in different
kinds. Endpoint components that fetch/send data from/to
an external system or transport protocol are designated
inbound/outbound adapters, or if bidirectional
inbound/outbound gateways. Several components are
used inside pipelines to process data, including: routers,
filters, transformers, splitters and aggregators. Some
endpoints, such as the service-activator and the gateway,
are used to mediate the interaction between pipelines and
other Java/Spring beans.

One-Way Inbound Adapter Outbound Adapter
Two-Way Inbound Gateway Outbound Gateway
In Spring Integration each message contains a payload
object and a set of headers (key-value pairs), and its
modelled by the generic interface Message<T>. A
Message is a read-only (immutable) object – once it is
created with some payload and headers it is not possible
to modify it. This is intended to preserve the analogy with
distributed message passing. The class MessageBuilder
can be used to conveniently create a message using a
fluent API and according to the Builder design-pattern.
» Example: Message API
public interface Message<T> {
T getPayload();
MessageHeaders getHeaders();
}
» Example: Creating Message w/ MessageBuilder
Message<Order> message = MessageBuilder.withPayload(order)
.setHeader("status", OrderStatus.OPEN)
.setExpirationDate(DateUtil.daysToExpire(30))
.setHeader("description", "Deliver to Dr. J.")
.build();

level programmatic API to send and receive messages to
channels.
» Example: Send & Receive w/ MessagingTemplate
@Bean
public MessagingTemplate messagingTemplate() {
return new MessagingTemplate();
}
@Autowired
private MessagingTemplate template;
Message<?> reply = template.sendAndReceive("orders", message);
if (reply.getHeaders().get("STATUS")==COMPLETED) { … }
A message Channel is used to connect endpoints. Channels
come in two broad categories, according to the reception
mode:
• Poolable – With active reception from a usually buffered
channel – e.g. QueueChannel, PriorityQueueChannel.
• Subscribable – Message delivery is done via a callback or
handler method – e.g. DirectChannel,
PublishSubscribeChannel.
Subscribable channels are more light-weighted and are used
more commonly. A PoolableChannel allows for more loose-
coupling between endpoints, but requires active pooling via a
Poller. Both the Direct & QueueChannel channels are used
for point-to-point communication – each message is delivered
to a single endpoint, while the PublishSubscribableChannel
is used for dissemination of messages – all receivers get a
“copy” of the message.
Channels can be defined as Spring beans using the core XML
namespace of Spring Integration. In the Java DSL, the utility
class MessageChannels provides factory methods and a
fluent API to create and configure the different kinds of
channels. Channels are light-weighted pure in-memory
abstractions. But a QueueChannel can be made persistent by
configuration of a MessageStore, or it can also be backed my
a queue in an external message-broker (JMS or AMQP).
Message delivery in Subscribable channels is by default node
with synchronous hand-off (same thread), but can also be
made asynchronous by configuring a TaskExecutor. When
components are referenced by endpoints but not explicitly
defined, the framework assume them to be auto-created
DirectChannel.
» Example: Defining Message Channels in XML
<int:channel id="orderChannel">
<int:queue capacity="100" />
</int:channel>
<int:publish-subscribe-channel id="pubsubChannel" task-
executor="someExecutor"/>
<task:executor id="taskExecutor"/>
» Example: Defining Message Channel in Java
@Bean
public MessageChannel fileContent() {
return MessageChannels.direct("fileContent").get();
}
Table below summarizes the channels types.
Channel Description
DirectChannel Subscribable; Point-to-Point;
Synchronous hand-off
ExecuterChannel Subscribable; Point-to-Point;
Asynchronous hand-off
PublishScubscribChannel Subscribable; Dissemination;
Synch or Asynch hand-off
QueueChannel FIFO Buffer; Pollable; Point-to-Point;
PriorityQueueChannel Priority Buffer; Pollable; Point-to-Point;
RendezvousChannel Zero-capacity queue (blocks sender);
Pollable; Point-to-Point; Async hand-off
Message flow trough a Channel can be observed and acted
upon using a ChannelInterceptor, whose API defines four
callback methods that notify message exchange at different
instants: preSend(), postSend(), preReceive(),
postReceive(). A commonly used ChannelInterceptor is a
WireTap, that copies message from a channel into another.
» Example: Setup ChannelInterceptor in Channel (XML)
<int:interceptors>
<ref bean="statsInterceptor"/>
</int:interceptors>
</int:channel>
@Component
public class StatsInterceptor extends ChannelInterceptorAdapter {
int nsent;
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
nsent++;
return message;
}
}
» Example: Setup WireTap in Channel (XML)
<int:interceptors>
<int:wire-tap channel="logger"/>

When using PollableChannels, like a Queue, endpoints need
to active fetch messages. This can be done with a Poller
component configured with a pooling policy. In XML, a Poller is
defined with element <poller>, using attributes fixed-rate,
fixed-delay, or cron to set the pooling policy. A Poller can be
configured in an individual endpoint (as XML sub-element), or
globally by setting attribute default="true". Using the Java
DSL, a Poller can be defined trough a bean of type
PollerMetaData.
» Example: Defining a Default Polling Policy (XML)
<int:poller fixed-rate="1000" default="true"/>
» Example: Defining a Default Polling Policy (Java)
@Bean(name = PollerMetadata.DEFAULT_POLLER)
public PollerMetadata poller() {
return Pollers.fixedRate(1000).get();
}
Pollers are also used to configure ChannelAdapters –
endpoints that invokes a Java method and acts as a message
source. The Poller define the rate at which the Java method is
invoked.
» Example: Defining an Inbound Channel Adapter (XML)
<int:inbound-channel-adapter ref="getStatus"
method="StatusService" channel="status">
<int:poller fixed-rate="5000"/>
</int:inbound-channel-adapter>
A Bridge is a component that is used to move messages
between two channels unchanged. This is useful when
integrating two sub-networks – e.g. that have different
expectations on the type or name of input/output channels, or
to throttle the publisher sub-network via buffering in a queue.
» Example: Using a Bridge to Throttle a Publisher
<int:channel id="orders" />
<int:bridge input-channel="orders"
output-channel="orderQueue"/>
<int:channel id="orderQueue" >
<int:queue capacity="100" />
</int:channel>
A Gateway is a proxy-factory component that allows Spring
beans to integrated seemly with Spring Integration networks,
by sending a message to a Channel when a method in the
generated proxy is invoked. That is, rather than explicitly using
the API of the MessagingTemplate to send messages, Spring
managed components simply invoke a method defined in an
interface. A Gateway is defined in XML with element
<gateway> using the attribute service-interface to specify the
interface the proxy should implement. Attribute default-
request-channel specifies the Channel where the proxy
sends the created messages. Annotation @Gateway can be
used in the interface methods when the interface as several
methods. When interface methods have a return value the
attribute default-reply-channel can be used to specify the
Channel where the proxy gets the response message from. If
not specified, the proxy dynamically creates a
(Direct)Channel. In both cases, the replyTo header of the
request message is set to reference the Channel where the
receiving endpoint should send the reply. The annotation
@IntegrationComponentScan can also be used to
automatically create Gateway proxies (without XML) by
searching for @Gateway annotated methods in interfaces (on
classpath).
» Example: Define Gateway in Java
<int:gateway id="orderService"
service-interface="org.myshop.OrderService"
default-request-channel="ordersChannel"
default-reply-channel="confirmationChannel" />
» Example: Interface Implemented by Gateway Proxy
public interface OrderService {
@Gateway
Confirmation submitOrder(Order order);
}
» Example: Using a Proxy Gateway
@Service
public class ShoppingService {
@Autowired
private OrderService orderService;
@Gateway
public Confirmation processOrder(Order order) {
//...
return new Confirmation(order);
}
}
A ServiceActivator is an endpoint that invokes a method in a
Spring bean (usually in a service layer component) when a
message arrives at an input channel in order to be processed.
The return value of the invoked method is forward in a
message to the output channel. A ServiceActivator is defined
in XML with element <service-activator>, using the attributes

Spring Integration
ref and method to specify the Java method to invoke.
Annotation @ServiceActivator can also be used to specify
which method to invoke. A third possibility, it to use a SPEL in-
lined script, defined in XML attribute expression.
» Example: Defining a ServiceActivator (XML+Java)
<int:service-activator input-channel="in" output-channel="out"
ref="OrderProcessor" method="processOrder"/>
@MessageEndpoint
public class OrderProcessor {
@ServiceActivator
Confirmation processOrder(Order order) {
return new Confirmation(order);
}
}
» Example: Define ServiceActivator w/ SPEL Expression
<int:service-activator input-channel="in" output-channel="out"
expression="@orderProcessor.process(payload,headers['type'])"/>
A Router is an endpoint that forwards incoming messages to
one among several output channels. A routing criteria is
defined – in Java or in SPEL – to select the output channel for
each individual message. The content of the message payload
and/or headers is usually used to make this decision. A generic
router is defined in XML with element <router>, using the
attributes ref and method to specify the Java method for the
routing criteria. Alternatively, annotation @Router be used to
specify which methods define the routing criteria. Additionally,
the stereotype annotation @MessageEndpoint is often used
to define criteria beans. SPEL scripts can also be used to
specify the routing criteria with XML attribute expression.
» Example: Defining a Router (XML) & Routing Criteria
<int:router input-channel="orderChannel" ref="orderRouter" />
@MessageEndpoint
public class OrderRouter {
@Router
public String routeOrder(Message<Order> message) {
return isUrgent(message) ? "vipChannel" : "altChannel";
}
}
» Example: Defining Routing Criteria w/ SPEL
<int:router input-channel="orderChannel"
expression="headers['type']"/>
<int:router input-channel="orderChannel"
expression="Orders.isXml(payload)?'xmlChannel':'csvChannel'"/>
More specialized kinds of routers are also available, such as
the PayloadTypeRouter that routes messages to channels
according to the type of the payload, or the
HeaderValueRouter that routes based on the value on an
header.
» Example: Routing w/ PayloadTypeRouter (XML)
<int:payload-type-router input-channel="orderChannel" default-
output-channel="miscOrderChannel" >
<int:mapping type="org.w3c.dom.Document"
channel="xmlOrderChannel" />
<int:mapping type="java.lang.String"
channel="csvOrderChannel" />
</int:payload-type-router>
» Example: Routing w/ HeaderValueRouter (XML)
<int:header-value-router input-channel="orderChannel"
header-name="status" >
<int:mapping value="CHECKED_OUT" channel="stockChannel" />
<int:mapping value="COMPLETED" channel="invoiceChannel" />
<int:mapping value="CANCELED" channel="cancelChannel" />
</int:header-value-router>
A message Filter is an endpoint that relays messages from an
input to an output channel conditionally. They are used to
discard messages based on payload or header values, and
detect invalid or non-conforming messages. A filter is defined
in XML with element <filter>, using attributes input-channel
and output-channel to specify the channel from where
message are received and relayed, respectively, and ref and
method for the filtering criteria. Alternatively, annotation
@Filter be used to specify which method defines the routing
criteria as well as the Filter configuration. A SPEL script can
also be used as filtering criteria with XML attribute expression.
By default, filtered-out messages – those for who the criteria
method returns false – are discarded. It is also possible to
make filtered-out messages throw an Exception, with XML
attribute throw-exception-on-rejection="true". Or,
alternatively, to be diverted to an alternative channel with
attribute discard-channel.
» Example: Defining Filter (XML) & Filtering Criteria
<int:filter ref="orderSelector" />
@MessageEndpoint
public class OrderSelector {
@Filter(inputChannel="in", outputChannel="out")
boolean filter(Order order) {
return OrderUtil.isValid(order);
}
}
» Example: Diverting Filtered Out Messages
<int:filter input-channel="in" output-channel="out"
ref="orderValidator" discard-channel="invalid" />
A message Transformer is an endpoint that transforms

Spring Integration
messages payload and/or headers, and can be used to
perform arbitrary transformations on payloads, convert payload
types, and add/change/remove headers. The XML element
<transformer> can be used to define a transformer. The
transformation function can be defined as Spring Bean
implementing interface MessageProcessor. Alternatively, a
POJO can be used when XML attribute method or Java
annotation @Transformer specifies the transformation
method.
» Example: Define & Configure Transformer (XML+Java)
<int:transformer id="invoiceTransformer"
input-channel="orderChannel" output-channel="invoiceChannel"
ref="orderTransform" method="createInvoice" />
@MessageEndpoint
public class InvoiceCreator {
@Transformer
public Invoice createInvoce(Order order) {
return new Invoice(order);
}
}
More specialized kinds of transformer are also available such
as the ObjectToStringTransformer that maps an object to its
String representation, or transformers to perform XML or
JSON (un)marshalling.
A Splitter is an endpoint that produces multiples output
messages out of a single input message. It is used to
decompose messages with composite payloads (e.g. a
collection or a structured object with child objects), into
separated messages one for each of component parts of the
payload (e.g. an Order may be split into a collection of
OrderItem). This is useful for processing the component parts
separately, followed possibly by latter (re)aggregation.
The XML element <splitter> is be used to define a Splitter,
with attribute ref naming a Spring bean implementing interface
SplittingCriteria. Alternatively, a POJO can be used when
XML attribute method or Java annotation @Splitter specifies
the splitting criteria. The method takes a Message or POJO
(for the payload) as parameter, and should return a List of
Message or payload objects.
» Example: Define & Configure Splitter (XML + Java)
<int:splitter id="orderSplitter"
input-channel="orderChannel" output-channel="itemChannel"
ref="orderSplitterBean" />
@MessageEndpoint("orderSplitterBean")
public class OrderSplitter {
@Splitter
public List<OrderItem> split(Order order) {
return order.getItems();
}
}
A Splitter copies the headers of the input message to the
output message when POJO payloads are used in the splitting
method. Additionally, it sets the following headers:
• CORRELATION_ID – is set with the value of the header ID
of the input message.
• SEQUENCE_SIZE – is set with the number of output
messages produced from the input message.
• SEQUENCE_NUMBER – is set with a ordering number
from 1 to SEQUENCE_SIZE.
These headers are set so that it possible to track the origin of
the message. For example, to reconstruct the original
messages after the component elements are further processed
by intermediate endpoints.
An Aggregator is an endpoint that combines multiple input
messages into a single output message (i.e. the converse of a
Splitter). A correlation strategy is used to decided which input
messages are to be aggregated with which other messages
(i.e. belong to the same message group or “bucket”). A release
strategy is used to determine when the message group is
complete and a single message should be produced out of all
the messages in the group. An aggregation criteria defines
how to assemble a single output message out of a group of
correlated messages. A typical use-case for an Aggregator
(but not the only one) is to reconstruct a composite message
out of multiple “child” messages that were earlier produced by
a Splitter (e.g. an Order (re)created out of a collection of
OrderItem). Messages that have the same correlation value
are collected together, and when the release is done, the
aggregation criteria is called to produce the combined output
message.
The XML element <aggregator> is be used to define an
Aggregator, with attribute ref naming a Spring bean
implementing interface AggregationCriteria. Alternatively, a
POJO can be used when XML attribute method or Java
annotation @Aggregator specifies the aggregation criteria.
The method takes a a List of Message or payload objects as
parameter, and should return a single Message or POJO (for
the combined payload).
The correlation and release strategies are specified with
attributes correlation-strategy and, release-strategy,
respectively, implementing interfaces CorrelationStrategy and
ReleaseStrategy. Alternatively, POJO can be used if attributes
correlation-strategy-method and release-strategy-method

Spring Integration
are specified. In the common case where the aggregation is
done over messages split earlier by a Splitter both strategies
are optional. This is because the default strategy is to
combined messages by the value of the CORRELATION_ID,
and to release them when SEQUENCE_SIZE equals the
number of available messages.
» Example: Aggregator w/ Default Correlation&Release
<int:aggregator id="orderAggregator"
input-channel="itemChannel" output-channel="orderChannel"
ref="orderAggregatation" />
@MessageEndpoint
public class OrderAggregation {
@Aggregator
public List<OrderItem> createOrder(Order order) {
return order.getItems();
}
}
» Example: Aggregator with Full Custom Configuration
<int:aggregator id="orderAggregator"
input-channel="itemChannel" output-channel="orderChannel"
ref="orderAggregatation" method="createOrder"
correlation-strategy="correlationStrategyBean"
correlation-strategy-method="correlate"
release-strategy="releaseStrategyBean"
release-strategy-method="release" />
When several endpoints are connected in a serial pipeline,
such that the output channel of previous component is the
input channel of the following one, it is possible to simplify the
configuration by defining a composite component that makes
this relationship explicit. The XML element <chain> defines an
endpoint Chain, that automatically wires the endpoints part of
the pipeline including the creation of intermediate
DirectChannel to connect the endpoints. The channel named
in the attribute input-channel is wired as input channel to the
first component in the pipeline, and the channel named in the
attribute output-channel (if specified) is wired as output
channel of the last component.
» Example: Defining a Chain as a Endpoint Pipeline
<int:chain input-channel="input" output-channel="output">
<int:filter ref="orderValidator" />
<int:header-enricher>
<int:header name="valid" value="true"/>
</int:header-enricher>
<int:service-activator ref="OrderService" method="submit"/>
</int:chain>
A Java DSL can also be used to create pipelines based on the
IntegrationFlow abstraction – similarly to the Chain – but
allowing Java lambda expressions to be used to define the
criteria strategies. An IntegrationFlow is defined as a Spring
Bean and created with a IntegrationFlowBuilder that
provides a fluent API to define the pipeline. The
IntegrationFlow is a meta-data descriptor used only during
configuration. To actually create the components from the
meta-data the annotation @EnableIntegration should be
used.
» Example: Using the IntegrationFlow DSL
@Bean
public IntegrationFlow orderFilesFlow() {
return IntegrationFlows
.from("orderFiles")
.filter((File f) -> f.length()<=100000)
.transform(Transformers.fileToString())
.transform(Transformers.fromJson(Order.class))
.filter((Order o) -> o.isValid())
.handle(OrderService::submit)
.get();
}
In the special case where messages payload is XML, it is
desirable to use XML specific technologies to process the
messages. XPath expressions – which are used to select the
sub-trees of an XML document that match a particular
expression – can be used to define strategies for a Spliter, a
Router, or a Filter (e.g. XPath expression //item returns the
list of all <item> elements in a XML document, so it can be
used as a splitting criteria). The element <xpath-expression>
from the spring-integration-xml namespace is used to define
XPath expression.
An XSLT script define an XML transformation, so it can also be
naturally to used to define a Transformer for XML payloads.
The XML element <xslt-transformer> defines a XSLT
transformer, with attribute xsl-resource naming the script file.
» Example: Splitting XML Payload via XPath
<int-xml:xpath-splitter id="orderItemSplitter"
input-channel="orderChannel" output-channel="itemsChannel">
<int-xml:xpath-expression expression="//item"/>
</int-xml:xpath-splitter>
» Example: XLST Transformer & XSLT Script
<int-xml:xslt-transformer id="xsltTransformerWithResource"
input-channel="withResourceIn" output-channel="output"
xsl-resource="order-version-migration.xsl"/>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/order">
<xsl:attribute name="priority" value="normal" />
</xsl:template>
</xsl:stylesheet>

Spring Integration
JMS integration is done trough four main components from the
spring-integration-jms XML namespace: <inbound-channel-
adapter>, to relay messages sent from a MessageChannel
to a JMS destination, <outbound-channel-adapter> to
receive JMS messages and relay them to a channel, and for
two-way communication the <inbound-gateway> to process
JMS messages and send a response, and the <outbound-
gateway> to send a SMS message and wait for a response.
» Example: Sending Channel Messages to JMS
<int-jms:inbound-channel-adapter id="jmsIn"
destination="ordersQueue" channel="ordersChannel" />
Integration with the file-system (reading & writing files) is done
with a few components from XML namespace spring-
integration-file such an <inbound-channel-adapter> that
pool a directory for new files and emits messages with the File
payload (the filename). Transformer class
FileToStringTransformer can be use to read the content of
the file as a message.
» Example: Pooling Directory & Reading File Content
<int-file:inbound-channel-adapter id="files"
directory="file:input" filename-pattern="*.csv">
<int:poller id="poller" fixed-rate="5000" />
</int-file:inbound-channel-adapter>
@Bean
@Transformer(inputChannel = "files",
outputChannel = "fileContentChannel")
public FileToStringTransformer fileToStringTransformer() {
return new FileToStringTransformer();
}
Spring Integration provides many additional integration
components – inbound and outbound adaptors and gateways
– for a variety of transport protocols and data stores, including:
FTP, AMQP, Redis Pub/Sub, GemFire, JDBC, HTTP,
TCP/UDP/IP, among other.
