RabbitMQ系列4 Spring整合RabbitMQ

Spring整合RabbitMQ

创建两个工程

在这里插入图片描述

添加依赖

消费者和生产者的依赖都一样

 </dependency>
    <!--spring集成Rabbit-->
    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit</artifactId>

                </configuration>
            </plugin>
        </plugins>
    </build>

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

        <rabbit:bindings>
            <rabbit:binding queue="spring_fanout_queue_1"/>
            <rabbit:binding queue="spring_fanout_queue_2"/>
        </rabbit:bindings>
    </rabbit:fanout-exchange>

            <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
       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rabbitmq connectionFactory -->
    <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}"/>

    <bean id="springQueueListener" class="com.itheima.rabbitmq.listener.SpringQueueListener"/>
    <!--<bean id="fanoutListener1" class="com.itheima.rabbitmq.listener.FanoutListener1"/>
    <bean id="fanoutListener2" class="com.itheima.rabbitmq.listener.FanoutListener2"/>
    <bean id="topicListenerStar" class="com.itheima.rabbitmq.listener.TopicListenerStar"/>
    <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>
