RabbitMQ入门教程(十六)：RabbitMQ与Spring集成

简介

集成示例基本目录结构

一：引入相关依赖

引入Spring核心的依赖和spring-rabbit依赖，注意spring-rabbit依赖不要使用最新的版本，这里使用的1.7.5.RELEASE，使用2.0.0的会报错

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>com.lin</groupId>
<artifactId>rabbit_c2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<properties>
<spring.version>4.2.3.RELEASE</spring.version>
</properties>

<dependencies>
<!-- 添加Spring依赖 -->

<version>${spring.version}</version>

<artifactId>spring-context-support</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>

</dependency>

<!--单元测试依赖 -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>

</dependency>

<!--spring单元测试依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
<scope>test</scope>
</dependency>

<!--rabbitmq依赖 1.7.5.RELEASE, 不要使用2.x.x版本会报错-->
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.7.5.RELEASE</version>
</dependency>

<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.0.1.Final</version>
</dependency>

</dependencies>
</project>

二：配置Rabbit连接参数application.properties

rabbit.host=127.0.0.1
rabbit.port=5672
rabbit.username=guest
rabbit.password=guest
rabbit.vhost=/

三：配置Spring的配置文件

applicationContext.xml Spring总的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" default-lazy-init="false">
<description>Spring总配置文件</description>
<context:component-scan base-package="com.mengday.rabbitmq" />
<context:annotation-config />
<context:spring-configured />

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true" />
<property name="locations">
<list>
<value>classpath*:/application.properties</value>
</list>
</property>
</bean>

<import resource="applicationContext-rabbit.xml"/>
</beans>

Spring对应的rabbit配置文件 applicationContext-rabbit.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd"> <!--配置connection-factory，指定连接rabbit server参数 -->
<rabbit:connection-factory id="connectionFactory"
host="${rabbit.host}"
port="${rabbit.port}"
username="${rabbit.username}"
password="${rabbit.password}"
virtual-host="${rabbit.vhost}"/>

<!--定义rabbit template用于数据的接收和发送 -->
<rabbit:template id="amqpTemplate"  connection-factory="connectionFactory" exchange="exchangeTest"/>

<!--通过指定下面的admin信息，当前producer中的exchange和queue会在rabbitmq服务器上自动生成 -->
<rabbit:admin connection-factory="connectionFactory" />

<!--定义queue -->
<rabbit:queue name="queueTest" durable="true" auto-delete="false" exclusive="false" />

<!-- 定义direct exchange，绑定queueTest -->
<rabbit:direct-exchange name="exchangeTest" durable="true" auto-delete="false">
<rabbit:bindings>
<rabbit:binding queue="queueTest" key="queueTestKey"></rabbit:binding>
</rabbit:bindings>
</rabbit:direct-exchange>

<!-- 消息接收者 -->
<bean id="messageReceiver" class="com.mengday.rabbitmq.MessageConsumer"></bean>

<!-- queue litener  自动监听队列，当有消息到达时会通知监听在对应的队列上的监听对象-->
<rabbit:listener-container connection-factory="connectionFactory">
<rabbit:listener queues="queueTest" ref="messageReceiver"/>
</rabbit:listener-container>

</beans>

四：消息监听

MessageConsumer.java

package com.mengday.rabbitmq;

public class MessageConsumer implements MessageListener {

public void onMessage(Message message) {
System.out.println("Received:" + message);
}
}

五：发送消息

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:conf/spring/applicationContext.xml" })
public class SpringRabbitTest extends AbstractJUnit4SpringContextTests {

@Autowired
private AmqpTemplate amqpTemplate;

@Test
public void sendMessage(){
Map<String, Object> log = new HashMap<String, Object>();
log.put("level", "info");
log.put("timestamp", new Date());
log.put("operateId", 666);
log.put("msg", "修改密码，修改前密码：123456，修改后密码：111111");

amqpTemplate.convertAndSend("queueTestKey", log);
}
}

六：运行结果
