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">

  <groupId>com.lin</groupId>
  <artifactId>rabbit_c2</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <properties>
    <spring.version>4.2.3.RELEASE</spring.version>
  </properties>

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"

     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"/>

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);
	}
}
