@Configuration
public class DirectRabbitConfig {

@Bean

// autoDelete:是否自动删除,当没有生产者或者消费者使用此队列,该队列会自动删除。
// return new Queue("TestDirectQueue",true,true,false);

3.3 功能实现
3.3.1 生产者
package com.auskat.demo.rabbitmq.consumer.controller;
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;
/**
* 类文件: SendMessageController
* <p>
* <p>
* 类描述:
* <p>
* 作 者: AusKa_T
* <p>
* 日 期: 2021/4/17 0017
* <p>
* 时 间: 19:35
* <p>
*/
@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";
}
}
3.3.2 消费者
package com.auskat.demo.rabbitmq.producer.receiver;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import java.util.Map;

* <p>
* 时 间: 19:37
* <p>
*/
@Component
@RabbitListener(queues = "TestDirectQueue") //监听的队列名称 TestDirectQueue
public class DirectReceiver {
@RabbitHandler
public void process(Map message) {
System.out.println("DirectReceiver消费者收到消息 : " + message.toString());
}
}
