阿里架构师直言：“没有实战都是纸上谈兵”！Redis实战PDF分享
1.在linux环境使用docker安装RabbitMQ
//拉取镜像 docker pull rabbitmq:management //启动镜像 docker run -di --name myrabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management安装成功后登陆控制台
2.生产者
pom.xml中引入RabbitMQ依赖
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-amqp --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> <version>1.3.5.RELEASE</version> </dependency>配置RabbitMQ服务端连接，和交换机名称
application.yml
spring: rabbitmq: port: 5672 username: admin password: admin host: 192.168.200.128 virtual-host: / order: fanout: exchange: order.fanout.exchange生产者向MQ发送消息
Producer.java
package com.cott.gmail.bootuserserviceprovider.mq; import org.springframework.amqp.rabbit.core.RabbitTemplate; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import java.util.Date; import java.util.UUID; @Component public class Producer { @Autowired private RabbitTemplate rabbitTemplate; @Value("${order.fanout.exchange}") private String exchangeName; public void sendMsg() { String orderId = UUID.randomUUID().toString(); String message = "你的订单信息是：" + orderId + ",日期是：" + new Date(); rabbitTemplate.convertAndSend(exchangeName, message); } }在用户接口的实现类中，调用生产者的方法
UserServiceImpl.java
package com.cott.gmail.bootuserserviceprovider.service.impl; import com.alibaba.dubbo.config.annotation.Service; import com.cott.gmail.bean.UserAddress; import com.cott.gmail.bootuserserviceprovider.mq.Producer; import com.cott.gmail.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import java.util.Arrays; import java.util.List; @Service @Component public class UserServiceImpl implements UserService { @Autowired Producer producer; @Override public List<UserAddress> getAddress(String uesrId) { producer.sendMsg(); UserAddress userAddress1 = new UserAddress(); userAddress1.setId(1); userAddress1.setUserAddress("1"); userAddress1.setUserId("1"); UserAddress userAddress2 = new UserAddress(); userAddress2.setId(2); userAddress2.setUserAddress("2"); userAddress2.setUserId("2"); return Arrays.asList(userAddress1, userAddress2); } }3.消费者
pom.xml中引入RabbitMQ依赖
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-amqp --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> <version>1.3.5.RELEASE</version> </dependency>配置RabbitMQ服务端信息，和交换机以及队列名称
application.yml
spring: rabbitmq: port: 5672 username: admin password: admin host: 192.168.200.128 virtual-host: / order: fanout: exchange: order.fanout.exchange queue: order.fanout.queue@RabbitListener注解，绑定队列，交换机，以及选择交换模式FANOUT
- @RabbitListener 可以标注在类上面，需配合 @RabbitHandler 注解一起使用
- @RabbitListener 标注在类上面表示当有收到消息的时候，就交给 @RabbitHandler 的方法处理，具体使用哪个方法处理，根据 MessageConverter 转换后的参数类型
Consumer.java（消费者）
package com.cott.gmail.bootorderserviceconsumer.service.impl; import org.springframework.amqp.core.ExchangeTypes; import org.springframework.amqp.rabbit.annotation.*; import org.springframework.stereotype.Component; @Component @RabbitListener(bindings = @QueueBinding(value = @Queue(value = "${order.fanout.queue}", autoDelete = "true"), exchange = @Exchange(value = "${order.fanout.exchange}", type = ExchangeTypes.FANOUT))) public class Consumer { @RabbitHandler public void processMessage(String msg) { System.out.format("Receiving Message: -----[%s]----- n.", msg); } }消费者中有调用生产者getAddress()的方法，生产者向MQ中发送一条消息，同时消费者监听MQ，消费消息。
OrderServiceImpl.java
package com.cott.gmail.bootorderserviceconsumer.service.impl; import com.alibaba.dubbo.config.annotation.Reference; import com.cott.gmail.bean.UserAddress; import com.cott.gmail.service.OrderService; import com.cott.gmail.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class OrderServiceImpl implements OrderService { @Reference UserService userService; @Override public List<UserAddress> initOrder(String id) { System.out.println("id= " + id); List<UserAddress> list = userService.getAddress("1"); for (UserAddress user : list ) { System.out.println(user.getUserAddress()); } return list; } }4.验证
先后启动生产者和消费者，在浏览器发起请求
消费者控制台输出
同时在RabbitMQ控制台查看监控日志
