[[boot-features-messaging]]
|
||||
== Messaging
|
||||
|
||||
The Spring Framework provides extensive support for integrating with messaging
|
||||
systems: from simplified use of the JMS API using `JmsTemplate` to a complete
|
||||
infrastructure to receive messages asynchronously. Spring AMQP provides a similar
|
||||
feature set for the ``Advanced Message Queuing Protocol'' and Boot also provides
|
||||
auto-configuration options for `RabbitTemplate` and RabbitMQ.
|
||||
|
||||
[[boot-features-jms]]
|
||||
== JMS
|
||||
|
||||
The `javax.jms.ConnectionFactory` interface provides a standard method of
|
||||
creating a `javax.jms.Connection` to interact with a JMS broker. In practice,
|
||||
you don't need to handle that yourself even if the `ConnectionFactory` is a
|
||||
central piece of the JMS infrastructure as most of the higher-level JMS
|
||||
components require a `ConnectionFactory` to operate.
|
||||
|
||||
|
||||
[[boot-features-hornetq]]
|
||||
==== HornetQ support
|
||||
|
||||
Spring Boot can auto-configure a `ConnectionFactory` when it detects that
|
||||
HornetQ is available on the classpath. By default, a `ConnectionFactory` using
|
||||
the `netty` transport protocol is configured, connecting to a broker running on
|
||||
the local machine with the default settings. It is also possible to connect to
|
||||
a running broker provided in the container or even embed the container in the
|
||||
application if the necessary classes are present.
|
||||
|
||||
NOTE: if you are using `spring-boot-starter-hornetq` the necessary dependencies
|
||||
to connect to an existing HornetQ instance are provided, as well as the Spring
|
||||
infrastructure to integrate with JMS. Adding `org.hornetq:hornetq-jms-server`
|
||||
to your application allows you to use the embedded mode.
|
||||
|
||||
HornetQ configuration is controlled by external configuration properties in
|
||||
`spring.hornetq.*`. For example, you might declare the following section
|
||||
in `application.properties`:
|
||||
|
||||
[source,properties,indent=0]
|
||||
----
|
||||
spring.hornetq.mode=native
|
||||
spring.hornetq.host=192.168.1.210
|
||||
spring.hornetq.port=9876
|
||||
----
|
||||
|
||||
When embedding the broker, you can chose if you want to enable persistence and
|
||||
the list of destinations that should be made available. These can be specified
|
||||
as a comma separated list to create them with the default options or you can
|
||||
define bean(s) of type `org.hornetq.jms.server.config.JMSQueueConfiguration`
|
||||
or `org.hornetq.jms.server.config.TopicConfiguration`, for advanced queue and
|
||||
topic configurations respectively.
|
||||
|
||||
See {sc-spring-boot-autoconfigure}/jms/hornetq/HornetQProperties.{sc-ext}[`HornetQProperties`]
|
||||
for more of the supported options.
|
||||
|
||||
No JNDI lookup is involved at all and destinations are resolved against their
|
||||
names, either using the ``name'' attribute in the HornetQ configuration or the
|
||||
names provided through configuration.
|
||||
|
||||
[[boot-features-activemq]]
|
||||
==== ActiveMQ support
|
||||
|
||||
Spring Boot can also configure a `ConnectionFactory` when it detects that
|
||||
ActiveMQ is available on the classpath. If the complete broker is available,
|
||||
an embedded broker is started and configured automatically if no broker URL
|
||||
is specified through configuration.
|
||||
|
||||
ActiveMQ configuration is controlled by external configuration properties in
|
||||
`spring.activemq.*`. For example, you might declare the following section
|
||||
in `application.properties`:
|
||||
|
||||
[source,properties,indent=0]
|
||||
----
|
||||
spring.activemq.broker-url=tcp://192.168.1.210:9876
|
||||
spring.activemq.user=admin
|
||||
spring.activemq.password=secret
|
||||
----
|
||||
|
||||
See {sc-spring-boot-autoconfigure}/jms/activemq/ActiveMQProperties.{sc-ext}[`ActiveMQProperties`]
|
||||
for more of the supported options.
|
||||
|
||||
By default, ActiveMQ creates a destination if it does not exist yet so destinations
|
||||
are resolved against their provided names.
|
||||
|
||||
[[boot-features-using-jms-template]]
|
||||
=== Using JmsTemplate
|
||||
Spring's `JmsTemplate` is auto-configured and you can `@Autowire` it directly
|
||||
into your own beans:
|
||||
|
||||
[source,java,indent=0]
|
||||
----
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.jms.core.JmsTemplate;
|
||||
import org.springframework.stereotype.Component;
|
||||
|
||||
@Component
|
||||
public class MyBean {
|
||||
|
||||
private final JmsTemplate jmsTemplate;
|
||||
|
||||
@Autowired
|
||||
public MyBean(JmsTemplate jmsTemplate) {
|
||||
this.jmsTemplate = jmsTemplate;
|
||||
}
|
||||
|
||||
// ...
|
||||
|
||||
}
|
||||
