SpringBoot整合RabbitMq之简单演示（Direct模式）

我是靠谱客的博主明亮过客，这篇文章主要介绍SpringBoot整合RabbitMq之简单演示（Direct模式），现在分享给大家，希望可以做个参考。

一。下载Erlang，RabbitMq并安装；见 https://blog.csdn.net/zhaodj5660/article/details/79813749

二。安装RabbitMQ-Plugins，这个相当于是一个管理界面，方便我们在浏览器界面查看RabbitMQ各个消息队列以及exchange的工作情况，安装方法是：打开命令行cd进入rabbitmq的sbin目录(我的目录是：D:Program FilesRabbitMQServerrabbitmq_server-3.7.4sbin)，输入：rabbitmq-plugins enable rabbitmq_management命令，稍等会会发现出现plugins安装成功的提示，默认是安装6个插件:

三。上代码--新建一个SpringBoot项目rabbitmq-hello；

导包：

name: rabbitmq-hello
rabbitmq:
host: localhost
port: 5672
username: guest
password: guest

3.2 配置RabbitMq配置类；

package com.zdj.rabbitmq;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* Created by Administrator on 2018/4/8.
*/
@Configuration
public class RabbitConfig {
@Bean
public Queue helloQueue(){
return new Queue("hello");
}
}

3.3 发送消息类HelloSender ；

import org.springframework.stereotype.Component;
import java.util.Date;
/**
* Created by Administrator on 2018/4/8.
*/
@Component
public class HelloSender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void send(){
String context="hello,传递消息时间 "+ new Date();
System.out.println("Sender : "+context);
this.rabbitTemplate.convertAndSend("hello",context);
}
}

3.4 接收消息类 HelloReceiver；

*/
@Component
@RabbitListener(queues = "hello")
public class HelloReceiver {
@RabbitHandler
public void process(String str){
System.out.println("Receiver: "+str);
}
}

import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = RabbitmqHelloApplication.class)
//
启动接收应用，测试发送的测试类
public class RabbitmqHelloApplicationTests {
@Autowired
private HelloSender sender;
@Test
public void hello() throws Exception{
sender.send();
}
}
