创建消息监听器
1.创建队列监听器
public class SpringQueueListener implements MessageListener {
@Override
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("接收路由名称为:%s,路由键为:%s,队列名为:%s的消息:%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
2.创建广播监听器
public class FanoutListener1 implements MessageListener {
@Override
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("广播监听器1:接收路由名称为:%s,路由键为:%s,队列名为:%s的消息:%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
3.创建通配符监听器
public class TopicListener1 implements MessageListener {
@Override
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("*号通配符监听器:接收路由名称为:%s,路由键为:%s,队列名为:%s的消息:%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
配置RabbitMQ
1.创建rabbitmq.properties
创建rabbitmq.properties参数配置文件
rabbitmq.host=ip
rabbitmq.port=5672
rabbitmq.username=test
rabbitmq.password=test
rabbitmq.virtual-host=/test
2.创建生产者配置文件
创建生产者配置文件spring-rabbitmq-producer.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:context="http://www.springframework.org/schema/context"
xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit.xsd">
<!--加载配置文件-->
<context:property-placeholder location="classpath:rabbitmq.properties"/>
<!-- 定义connectionFactory -->
<rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
port="${rabbitmq.port}"
username="${rabbitmq.username}"
password="${rabbitmq.password}"
virtual-host="${rabbitmq.virtual-host}"/>
<!--定义管理交换机、队列-->
<rabbit:admin connection-factory="connectionFactory"/>
<!--定义队列,不存在则自动创建;不绑定到交换机则绑定到默认交换机
默认交换机类型为direct,名字为:"",路由键为队列的名称-->
<!--
id:bean的名称
name:queue的名称
auto-declare:自动创建队列
auto-delete:自动删除队列。 最后一个消费者和该队列断开连接后,自动删除队列
exclusive:是否独占连接
durable:是否持久化
-->
<rabbit:queue id="spring_queue" name="spring_queue" auto-declare="true"/>
<!--定义队列,不存在则自动创建-->
<rabbit:queue id="spring_fanout_queue_1" name="spring_fanout_queue_1" auto-declare="true"/>
<!--定义队列,不存在则自动创建-->
<rabbit:queue id="spring_fanout_queue_2" name="spring_fanout_queue_2" auto-declare="true"/>
<!--定义广播类型交换机;并绑定上述两个队列-->
<rabbit:fanout-exchange id="spring_fanout_exchange" name="spring_fanout_exchange" auto-declare="true">
<rabbit:bindings>
<rabbit:binding queue="spring_fanout_queue_1" />
<rabbit:binding queue="spring_fanout_queue_2"/>
</rabbit:bindings>
</rabbit:fanout-exchange>
<!--定义队列,不存在则自动创建-->
<rabbit:queue id="spring_direct_queue_1" name="spring_direct_queue_1" auto-declare="true"/>
<!--定义队列,不存在则自动创建-->
<rabbit:queue id="spring_direct_queue_2" name="spring_direct_queue_2" auto-declare="true"/>
<!--定义路由类型交换机;并绑定上述两个队列-->
<rabbit:direct-exchange name="spring_direct_exchange" >
<rabbit:bindings>
<!--direct 类型的交换机绑定队列 key :路由key queue:队列名称-->
<rabbit:binding queue="spring_direct_queue_1" key="error"></rabbit:binding>
<rabbit:binding queue="spring_direct_queue_2" key="info"></rabbit:binding>
</rabbit:bindings>
</rabbit:direct-exchange>
<!--定义队列,不存在则自动创建-->
<rabbit:queue id="spring_topic_queue1" name="spring_topic_queue1" auto-declare="true"/>
<!--定义队列,不存在则自动创建-->
<rabbit:queue id="spring_topic_queue2" name="spring_topic_queue2" auto-declare="true"/>
<!--定义通配符类型交换机;并绑定上述两个队列-->
<rabbit:topic-exchange id="spring_topic_exchange" name="spring_topic_exchange" auto-declare="true">
<rabbit:bindings>
<rabbit:binding pattern="orange.*" queue="spring_topic_queue1"/>
<rabbit:binding pattern="old.#" queue="spring_topic_queue2"/>
</rabbit:bindings>
</rabbit:topic-exchange>
<!--定义rabbitTemplate对象-->
<rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/>
</beans>
3.创建消费者配置文件
创建消费者配置文件spring-rabbitmq-consumer.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:context="http://www.springframework.org/schema/context"
xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit.xsd">
<!--加载配置文件-->
<context:property-placeholder location="classpath:rabbitmq.properties"/>
<!-- 定义connectionFactory -->
<rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
port="${rabbitmq.port}"
username="${rabbitmq.username}"
password="${rabbitmq.password}"
virtual-host="${rabbitmq.virtual-host}"/>
<!-- 创建消费者监听Bean -->
<bean id="springQueueListener" class="cn.ybzy.rabbitmq.listener.SpringQueueListener"/>
<bean id="fanoutListener1" class="cn.ybzy.rabbitmq.listener.FanoutListener1"/>
<bean id="fanoutListener2" class="cn.ybzy.rabbitmq.listener.FanoutListener2"/>
<bean id="topicListener1" class="cn.ybzy.rabbitmq.listener.TopicListener1"/>
<bean id="topicListener2" class="cn.ybzy.rabbitmq.listener.TopicListener2"/>
<!-- 消费者监听与队列的绑定 -->
<rabbit:listener-container connection-factory="connectionFactory" auto-declare="true">
<rabbit:listener ref="springQueueListener" queue-names="spring_queue"/>
<rabbit:listener ref="fanoutListener1" queue-names="spring_fanout_queue_1"/>
<rabbit:listener ref="fanoutListener2" queue-names="spring_fanout_queue_2"/>
<rabbit:listener ref="topicListener1" queue-names="spring_topic_queue_1"/>
<rabbit:listener ref="topicListener2" queue-names="spring_topic_queue_2"/>
</rabbit:listener-container>
</beans>
4.加载rabbitmq配置文件
在spring.xml配置文件中引入rabbitmq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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="spring-rabbitmq-producer.xml"></import>
<import resource="spring-rabbitmq-consumer.xml"></import>
</beans>
发送消息测试
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring.xml")
public class ProducerTest {
/**
* 开启消费者监听
*/
@Test
public void consumer(){
while (true){
}
}
//注入 RabbitTemplate
@Autowired
private RabbitTemplate rabbitTemplate;
/**
* 发送简单消息
*/
@Test
public void testHelloWorld(){
rabbitTemplate.convertAndSend("spring_queue","spring_queue...");
}
/**
* 发送fanout类型消息
*/
@Test
public void testFanout(){
rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring_fanout....");
}
/**
* 发送topic类型消息
*/
@Test
public void testTopics(){
rabbitTemplate.convertAndSend("spring_topic_exchange","old.orange.rabbit","spring_topic....");
}
}
查看控制台
执行消费者监听test,依次执行简单模式、fanout类型、topic类型发送消息test。
一加载spring.xml文件就创建了如下队列及交换器。
