一、新建springboot项目,引入依赖Web、RabbitMQ
二、配置（去官网参考配置）
访问官网http://spring.io/，选中PROJECTS
选择sprinmgboot
选择Spring AMQP
参考官网示例：
首先修改配置文件application.properties，添加如下配置
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=123456三、编码
package com.jxy.rabbitmq;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* 创建消息队列
* @author Administrator
*
*/
@Configuration
public class QueueConfig {
/**
* 创建队列
* @return
*/
@Bean
public Queue createQueue() {
return new Queue("first-queue");
}
}
package com.jxy.rabbitmq;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
/**
* 消息发送者
* @author Administrator
*
*/
@Component
public class Sender {
@Autowired
private AmqpTemplate amqpTemplate;
public void send(String msg) {
amqpTemplate.convertAndSend("first-queue",msg);
}
}
package com.jxy.rabbitmq;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
/**
* 消息接收者
* @author Administrator
*
*/
@Component
public class Receiver {
@RabbitListener(queues="first-queue")
public void process(String msg) {
System.out.println("接收消息:"+msg);
}
}
package com.jxy.rabbitmq;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes=DemoRabbitmqApplication.class)
public class QueueTest {
@Autowired
private Sender sender;
@Test
public void testSend() {
this.sender.send("hi rabbitMQ");
}
}
四、运行结果
运行后报错：

解决方法如下：
1.登录监控平台
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=123456
访问地址http://[spring.rabbitmq.host]:1[spring.rabbitmq.port]
2.选中标签【admin】--【users】，在用户列表点击需要授权的用户
点击【set permission】按钮
设置完成后，重试即可。
