使用SpringMVC @Async异步执行方法的笔记 （转载）

原文：http://blog.csdn.net/yuwenruli/article/details/8514393

 测试代码：

@RunWith(SpringJUnit4ClassRunner.class)</p>@ContextConfiguration(locations = { "/spring/*.xml" })  
public class JobUtilsTest{  
      
    @Autowired  
    private DaoService service;  
  
    @Test  
    public void testAsync() throws Exception {  
        System.out.println("start" );  
        service.update(); // ★ 假设这个方法会比较耗时，需要异步执行  
        System.out.println("end");  
          
          
        Thread.sleep(3000); // 因为junit结束会结束jvm，所以让它等会异步线程  
    }  
}

 DaoService代码：

@Service  
public class DaoService {  
    @Async  
    public void update() {  
        try {  
            Thread.sleep(2000);  
            // do something  
        } catch (InterruptedException e) {  
            e.printStackTrace();  
        }  
        System.out.println("operation complete.");  
    }  
}
