RabbitMQ系列4 Spring整合RabbitMQ
Spring整合RabbitMQ
创建两个工程
添加依赖
消费者和生产者的依赖都一样
</dependency>

配置整合
1.rabbitMQ连接参数配置文件
rabbitmq.properties
rabbitmq.host=192.168.12.135
rabbitmq.port=5672
rabbitmq.username=heima
rabbitmq.password=heima
rabbitmq.virtual-host=/itcast
2.Spring整合rabbitMQ配置文件
生产者端
spring-rabbitmq.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>

<!--定义持久化队列,不存在则自动创建;不绑定到交换机则绑定到默认交换机

<rabbit:binding pattern="itcast.#" queue="spring_topic_queue_well2"/>
</rabbit:bindings>
</rabbit:topic-exchange>
<!--定义rabbitTemplate对象操作可以在代码中方便发送消息-->
<rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/>
</beans>
消费者端
<?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

<bean id="springQueueListener" class="com.itheima.rabbitmq.listener.SpringQueueListener"/>
<!--<bean id="fanoutListener1" class="com.itheima.rabbitmq.listener.FanoutListener1"/>

<bean id="topicListenerWell" class="com.itheima.rabbitmq.listener.TopicListenerWell"/>
<bean id="topicListenerWell2" class="com.itheima.rabbitmq.listener.TopicListenerWell2"/>-->
<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="topicListenerStar" queue-names="spring_topic_queue_star"/>
<rabbit:listener ref="topicListenerWell" queue-names="spring_topic_queue_well"/>
<rabbit:listener ref="topicListenerWell2" queue-names="spring_topic_queue_well2"/>-->
</rabbit:listener-container>
</beans>
消费者端编写MessageListener接口的实现类
package com.itheima.rabbitmq.listener;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
public class SpringQueueListener implements MessageListener {
@Override
public void onMessage(Message message) {
System.out.println(new String(message.getBody()));
}
}
生产者者端发送消息
使用Autowired自动注入rabbitTemplate,然后使用convertAndSend方法发送消息
@Autowired
private RabbitTemplate rabbitTemplate;
@Test
public void test1(){
rabbitTemplate.convertAndSend("spring_queue","Hello word!!");
}
3.配置项讲解
rabbit:queue/
id:bean的名称
name:queue的名称
auto-declare:自动创建
auto-delete:自动删除。 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
durable:是否持久化
示例
**
<rabbit:queue id="spring_fanout_queue_1" name="spring_fanout_queue_1" auto-declare="true"/>
<rabbit:template />
id:bean的名称
connection-factory:工厂bea的名称
示例
<!--定义rabbitTemplate对象操作可以在代码中方便发送消息-->
<rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/>
rabbit:fanout-exchange/
id:bean的名称
name:交换机的名称
auto-declare:自动删除。 最后一个队列和该交换机断开连接后,自动删除交换机
交换机绑定队列
<rabbit:bindings>
<rabbit:binding queue="spring_fanout_queue_1" />
<rabbit:binding queue="spring_fanout_queue_2"/>
</rabbit:bindings>
示例
**
<!--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>
