SSM整合RabbitMQ，Spring4.x整合RabbitMQ

前言

SSM框架整合RabbitMQ【比较简单，复制粘贴可用】
本人使用的Spring版本是4.x

版本

RabbitMQ相关
erl10.0.1
RabbitMQ3.7.9
安装步骤参考：https://www.cnblogs.com/saryli/p/9729591.html

相关依赖
spring4.0.2.RELEASE
spring-rabbit1.3.5.RELEASE

实现

目录参考

这是我整合时的项目结构
关键：rabbitmq文件包和rabbitmq.properties、spring-rabbitmq.xml、spring-mvc.xml

pom.xml依赖

在现成的SSM项目中整合

rabbitmq.properties配置文件

将 rabbitmq.properties配置文件添加到resources目录下

mq.host=127.0.0.1
mq.username=guest
mq.password=guest
mq.port=5672
mq.virtual-host=/

spring-rabbitmq.xml

将spring-rabbitmq.xml添加到resources目录下

spring-mvc.xml或applicationContext.xml

我这里使用的spring-mvc.xml，根据自己配置文件使用

<import resource="classpath:spring-rabbitmq.xml" />

将这个import引入添加到 spring-mvc.xml 里的最前面，如果不添加到前面可能会报错

rabbitmq目录下

这个目录下的java文件已在spring-rabbitmq.xml中进行扫描注入

MessageConsumer.java

说明：MessageConsumer和MessageConsumer2其实都可以使用同一个类，修改xml指向即可，但是分开明了些

package com.rabbitmq;

import java.nio.charset.Charset;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

/**
 * @Title消息消费者
 * @date 2023/10/8
 */
public class MessageConsumer implements MessageListener {

    @Override
    public void onMessage(Message message) {
    	// 逻辑处理
        System.out.println("message------->:" + new String(message.getBody(), Charset.forName("utf-8")));
    }
    
}

MessageConsumer2.java

package com.rabbitmq;

import java.nio.charset.Charset;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

/**
 * @Title消息消费者2
 * @date 2023/10/8
 */
public class MessageConsumer2 implements MessageListener {

    @Override
    public void onMessage(Message message) {
    	// 逻辑处理
        System.out.println("message2------->:" + new String(message.getBody(), Charset.forName("utf-8")));
    }
    
}

MessageProducer.java

package com.rabbitmq;

import javax.annotation.Resource;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.stereotype.Service;

/**
 * @Title 消息生产者
 * @date 2023/10/8
 */
@Service
public class MessageProducer {

    @Resource
    private AmqpTemplate amqpTemplate;

    
    public void sendMessage(String key, Object message){
        amqpTemplate.convertAndSend(key, message);
    }
    
}

MessageConstant.java

package com.rabbitmq;

/**
 * @Title 消息队列常量
 * @date 2023/10/8
 */
public class MessageConstant{

	public static String queueTestKey = "queueTestKey";
	public static String queueTestKey1 = "queueTestKey1";
    
	
}

测试调用

比如这个下面在某个类里作为接口调用测试

	@Autowired
    private MessageProducer messageProducer;

	@RequestMapping(value = "/testMq")
    @ResponseBody
    public Result testMq(HttpServletRequest request) throws IOException {
        messageProducer.sendMessage(MessageConstant.queueTestKey, "登录");
        messageProducer.sendMessage(MessageConstant.queueTestKey1, "退出");
        return Result.success("测试成功");
    }

调用接口后打印结果

连接结果

以上即可！

扩展

包括消息手动确认，消息失败重新加入队列处理

消息重发

package com.rabbitmq;

import java.nio.charset.Charset;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.core.ChannelAwareMessageListener;

import com.rabbitmq.client.Channel;

/**
 * @Title 消息消费者
 * @date 2023/10/8
 */
public class MessageConsumer2 implements ChannelAwareMessageListener {
	
	private int aa = 1;

	@Override
	public void onMessage(Message message, Channel channel) throws Exception {
		try {
		
			// 逻辑处理
			if(aa == 1) {
				aa = 2;
				int a = 1/0;
			}
			
			System.out.println("成功处理确认message2------->:" + new String(message.getBody(), Charset.forName("utf-8")));
			// 消费者ack确认【消息处理成功确认】
	        channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
		}catch (Exception e) {
			System.out.println("失败重新入队message2------->:" + new String(message.getBody(), Charset.forName("utf-8")));
			// 消费者reject确认【消息失败重新加入队列-重发】
			channel.basicReject(message.getMessageProperties().getDeliveryTag(), true);
		}
	}
    
}
