暂时只介绍Work Queue。
其他的工作模式其实都差不多 可以试着自己往里面加.
这只是个简单架子。
使用springboot 2.x 版本.

写入一个java类用来配置rabbitmq

生产者代码(Controller)
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.support.CorrelationData;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class RabbitSender {
//自动注入RabbitTemplate模板类
@Autowired
private RabbitTemplaterabbitTemplate;
@GetMapping("/send")
public void send()throws Exception {
String s ="123456";
//id + 时间戳 全局唯一
CorrelationData correlationData =new CorrelationData("1234567890");
rabbitTemplate.convertAndSend("exchange-1","send", s, correlationData);
}
}
将此注解@EnableRabbit 加在@SpringBootApplication 后!
