springboot学习入门简易版七---springboot2.0使用@Async异步执行方法（17)

@SpringBootApplication
@EnableAsync //开启异步调用
public class StartApplication {

@RestController
public class AsyncController {
    private final static Logger logger=LoggerFactory.getLogger(WebLogAspect.class);
    @Autowired
    private AsyncService asyncService;
    
    @RequestMapping("/testAsync")
    public String testAsync() {
        logger.info("1");
        String result=asyncService.asynTest();
        logger.info("4");
        return result;
    }
}

@Service
public class AsyncService {
    private final static Logger logger=LoggerFactory.getLogger(WebLogAspect.class);
    
    @Async  //相当于重新开辟单独线程执行该方法
    public String asynTest() {
        logger.info("2");
        try {
            Thread.sleep(5000);
        }catch(Exception e) {
            
        }
        logger.info("3");
        return "success";
    }
}
