异步任务

Spring Boot异步任务

1. 启动程序加上@EnableAsync注解
2. 方法上面加上@Async注解

代码：

@EnableAsync
@SpringBootApplication
public class Springboot4TaskApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(Springboot4TaskApplication.class, args);
    }
}

@RestController
public class AsyncController 
    
    @Autowired
    AsyncService asyncService;

    @GetMapping("/hello")
    public String hello(){
        asyncService.hello();
        return "success";
    }

}

@Service
public class AsyncService {
    
    @Async
    public void hello(){
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("format data ....");
    }
}
