配置RabbitMq 的Exchange

 

配置queue

 

 application.yml配置

spring:
  rabbitmq:
    host: localhost
    port: 5672
    username: xia
    password: *******
      #虚拟host 可以不设置,使用server默认host
    #virtual-host: w3cschool

　　

 

DirectRabbitConfig.java 配置类 

package top.xzhand.rabbit;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 **/
@Configuration
public class DirectRabbitConfig {

    //队列 起名：TestDirectQueue
    @Bean
    public Queue TestDirectQueue() {
        return new Queue("TestDirectQueue",true);  //true 是否持久
    }

    //Direct交换机 起名：TestDirectExchange
    @Bean
    DirectExchange TestDirectExchange() {
        return new DirectExchange("TestDirectExchange");
    }

    //绑定  将队列和交换机绑定, 并设置用于匹配键：TestDirectRouting
    @Bean
    Binding bindingDirect() {
        return BindingBuilder.bind(TestDirectQueue()).to(TestDirectExchange()).with("TestDirectRouting");
    }
}

消息产生者 

SendMessageController.java 

package top.xzhand.rabbit;

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

/**
 * 消息产生者
 * @Description :
 **/
@RestController
public class SendMessageController {

    @Autowired
    RabbitTemplate rabbitTemplate;  //使用RabbitTemplate,这提供了接收/发送等等方法

    @GetMapping("/sendDirectMessage")
    public String sendDirectMessage() {
        String messageId = String.valueOf(UUID.randomUUID());
        String messageData = "test message, hello!";
        String createTime = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        Map<String,Object> map=new HashMap<>();
        map.put("messageId",messageId);
        map.put("messageData",messageData);
        map.put("createTime",createTime);
        //将消息携带绑定键值：TestDirectRouting 发送到交换机TestDirectExchange
        rabbitTemplate.convertAndSend("TestDirectExchange", "TestDirectRouting", map);
        return "ok";
    }


}

消息监听消费 

DirectReceiver.java 

package top.xzhand.rabbit;


import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

import java.util.Map;

/**
 * 消息监听，消费
 */
@Component
@RabbitListener(queues = "TestDirectQueue")//监听的队列名称 TestDirectQueue
public class DirectReceiver {

    @RabbitHandler
    public void process(Map testMessage) {
        System.out.println("DirectReceiver消费者收到消息  : " + testMessage.toString());
    }

}
