Springboot配置多个的RabbitMQ地址

1. rabbitTemplate实现自amqpTemplate接口，需引入spring-boot-starter-amqp依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2. 配置application.yml文件,我这边是配置两个mq，分别为：mq_a，mq_b

###服务启动端口号
server:
  port: 8088
spring:
	rabbitmq:
	    mq_a:
	        host: 15.201.x.01
	        port: 5672
	        username: admin
	        password: admin
	    mq_b:
	      host: 15.201.x.02
	      port: 60060
	      username: user
	      password: user

3. 分别配置RabbitTemplate

package com.thg.config;

import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

@Configuration
public class MqFlagByAConfig {
    
    

    @Value("${spring.rabbitmq.mq_a.host}")
    private String host;

    @Value("${spring.rabbitmq.mq_a.port}")
    private int port;

    @Value("${spring.rabbitmq.mq_a.username}")
    private String username;

    @Value("${spring.rabbitmq.mq_a.password}")
    private String password;

    @Bean("mqFlagByAConfigConnectionFactory")
    @Primary
    public ConnectionFactory mqFlagByAConfigConnectionFactory(){
    
    
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setHost(host);
        connectionFactory.setPort(port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        return connectionFactory;
    }

    @Bean(name="mqaRabbitTemplate")
    public RabbitTemplate mqaRabbitTemplate(@Qualifier("mqFlagByAConfigConnectionFactory") ConnectionFactory connectionFactory){
    
    
        RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
        return rabbitTemplate;
    }

}

package com.thg.config;

import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

@Configuration
public class MqFlagByBConfig {
    
    

    @Value("${spring.rabbitmq.mq_b.host}")
    private String host;

    @Value("${spring.rabbitmq.mq_b.port}")
    private int port;

    @Value("${spring.rabbitmq.mq_b.username}")
    private String username;

    @Value("${spring.rabbitmq.mq_b.password}")
    private String password;

    @Bean("mqFlagByBConfigConnectionFactory")
    public ConnectionFactory mqFlagByBConfigConnectionFactory(){
    
    
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setHost(host);
        connectionFactory.setPort(port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        return connectionFactory;
    }

    @Bean(name="mqbRabbitTemplate")
    public RabbitTemplate mqbRabbitTemplate(@Qualifier("mqFlagByBConfigConnectionFactory") ConnectionFactory connectionFactory){
    
    
        RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
        return rabbitTemplate;
    }
}

4. 使用时注入自己需要的template模板，可以写一个类似这样得工具类，这样方便管理调用。

package com.thg.mq;

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

import javax.annotation.Resource;

@Component
public class SendMessage {
    
    
	//注入A模板
    @Resource(name = "mqaRabbitTemplate")
    private RabbitTemplate mqaRabbitTemplate;
    
	//注入B模板
	@Resource(name = "mqbRabbitTemplate")
    private RabbitTemplate mqbRabbitTemplate;

	/**
	*交换机
	**/
    private final static String exChange_police_action ="police_action";

	public void sendMessage(String message){
    
    
		//发送A模板数据
		this.mqaRabbitTemplate.convertAndSend(
			exChange_police_action,"test","A---->"+message);

		//发送B模板数据
		this.mqbRabbitTemplate.convertAndSend("test","B---->"+message);
    }

}

5. 可以写个junit测试一下，我这边使用controller调用得

package com.thg.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@RestController
public class TestController {
    
    

	//注入工具类
    @Autowired
    private SendMessage sendMQMessage;

    @RequestMapping(value = "/testMq", method = RequestMethod.POST)
    public String testMq() {
    
    
		sendMQMessage.sendMessage("测试测试测试！！！");
    }
