27-异步任务
作者:互联网
异步任务
1.创建新项目
2.service层
@Service
public class AsyncService {
//告诉spring这是一个异步的方法
@Async
public void hello(){
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("数据正在处理...");
}
}
3.controller层
@RestController
public class AsyncController {
@Autowired
private AsyncService asyncService;
@RequestMapping("/hello")
public String hello(){
asyncService.hello();
return "ok";
}
}
4.主程序开启异步注解功能
//开启异步注解功能
@EnableAsync
@SpringBootApplication
public class Spring09TestApplication {
public static void main(String[] args) {
SpringApplication.run(Spring09TestApplication.class, args);
}
}
- 访问效果就是直接返回ok,但是控制台等三秒后 输出 数据正在处理…
