1、安装rabbitmq docker安装，拉取镜像 docker pull rabbitmq:management 创建容器并启动 docker run -d --name rabbitmq --publish 5671:5671 --publish 5672:5672 --publish 4369:4369 --publish 25672:25672 --publish 15671:15671 --publish 15672:15672 rabbitmq:management 管理地址： http://localhost:15672/ 用户名：guest 密码：guest

2、配置springboot （1）pom.xml添加依赖 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency>

（2）添加rabbit配置文件，配置server信息 import org.springframework.amqp.core.Queue; import org.springframework.amqp.rabbit.connection.CachingConnectionFactory; import org.springframework.amqp.rabbit.connection.ConnectionFactory; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /**

（3）创建生产者，循环下发四个任务，用sleep模拟任务处理时间，一个.代码任务处理1s的时长，分别有四个不同时长的任务下发 import org.springframework.amqp.core.AmqpTemplate; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /**

（4）创建两个消费者Receiver1，Receiver2处理队列的任务

Receiver1： import org.springframework.amqp.rabbit.annotation.RabbitHandler; import org.springframework.amqp.rabbit.annotation.RabbitListener; import org.springframework.stereotype.Component; /**

@Author 冯战魁
@Date 2018/1/12 下午3:06 */ @Component @RabbitListener(queues = "hello") public class RabbitReceiver1 { @RabbitHandler public void process(String content){ System.out.println("Receiver1 : " + content); try { dowork(content); } catch (InterruptedException e) { e.printStackTrace(); } } public void dowork(String content) throws InterruptedException{ for (char ch: content.toCharArray()) { if (ch == '.'){ Thread.sleep(1000); } } } }

Receiver2： import org.springframework.amqp.rabbit.annotation.RabbitHandler; import org.springframework.amqp.rabbit.annotation.RabbitListener; import org.springframework.stereotype.Component; /**

@Author 冯战魁
@Date 2018/1/12 下午3:06 */ @Component @RabbitListener(queues = "hello") public class RabbitReceiver2 { @RabbitHandler public void process(String content){ System.out.println("Receiver2 : " + content); try { dowork(content); } catch (InterruptedException e) { e.printStackTrace(); } } public void dowork(String content) throws InterruptedException{ for (char ch: content.toCharArray()) { if (ch == '.'){ Thread.sleep(1000); } } } } （5）验证代码启动springboot，执行生产者的接口 http://localhost:8080/sender 然后查看终端输出的信息，如图所示
