使⽤SpringMVC@Async异步执⾏⽅法的笔记（转载）
代码：
@RunWith(SpringJUnit4ClassRunner.class)</p>@ContextConfiguration(locations = { "/spring/*.xml" })
public class JobUtilsTest{
@Autowired
private DaoService service;
@Test
public void testAsync() throws Exception {
spring framework表达式assignSystem.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.");
}
}
