RabbitMQ是开源消息队列系统，用erlang语言开发。如果不了解可以查看官网http://www.rabbitmq.com/
这篇文章介绍一个springboot简单整合RabbitMQ。
1.安装rabbitmq，自行百度即可，方法很多。
2.启动rabbitmq，成功如下图：
可以访问http://localhost:15672/查看管理页面
新建项目，pom文件加入依赖，完整pom如下：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.dalaoyang</groupId> <artifactId>springboot_rabbitmq</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>springboot_rabbitmq</name> <description>springboot_rabbitmq</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
新建一个消息发送者Sender，使用AmqpTemplate将消息发送到消息队列message中去。代码如下：
package com.dalaoyang.sender;
import org.apache.log4j.Logger;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
* @author dalaoyang
* @Description
* @project springboot_learn
* @package com.dalaoyang.send
* @email yangyang@dalaoyang.cn
* @date 2018/4/25
*/
@Component
public class Sender {
Logger logger = Logger.getLogger(Sender.class);
@Autowired
private AmqpTemplate amqpTemplate;
public String send(){
String context = "简单消息发送";
logger.info("简单消息发送时间："+new Date());
amqpTemplate.convertAndSend("message", context);
return "发送成功";
}
}创建消息接收者Receiver，使用注解@RabbitListener(queues = “message”)来监听message的消息队列@RabbitHandler来实现具体消费。
package com.dalaoyang.receiver;
import org.apache.log4j.Logger;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
* @author dalaoyang
* @Description
* @project springboot_learn
* @package com.dalaoyang.receiver
* @email yangyang@dalaoyang.cn
* @date 2018/4/25
*/
@Component
@RabbitListener(queues = "message")
public class Receiver {
Logger logger = Logger.getLogger(Receiver.class);
@RabbitHandler
public void process(String Str) {
logger.info("接收消息："+Str);
logger.info("接收消息时间："+new Date());
}
}然后看一下配置信息，因为是简单整合，所以只配置了端口和rabbitmq的信息，如下：
##端口号 server.port=8888 ##rabbitmq spring.rabbitmq.host=localhost spring.rabbitmq.port=5672 spring.rabbitmq.username=guest spring.rabbitmq.password=guest
创建一个controller，这里仅用来测试，代码如下：
package com.dalaoyang.controller;
import com.dalaoyang.sender.Sender;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author dalaoyang
* @Description
* @project springboot_learn
* @package com.dalaoyang.controller
* @email yangyang@dalaoyang.cn
* @date 2018/4/25
*/
@RestController
public class TestController {
@Autowired
private Sender sender;
@GetMapping("hello")
public String helloTest(){
sender.send();
return "success";
}
}启动项目，访问http://localhost:8888/hello然后观看控制台可以看到消息已经发送成功。
