pring的@Async功能，用的时候一定要注意：
1、异步方法和调用类不要在同一个类中。
2、xml里需要加入这一行 <task:annotation-driven/>
下面的可以直接粘贴使用

以下是demo
@Autowired
private AsyncDemo asyncDemo; @Action("/a")
public String a() throws Exception {
asyncDemo.asyncInvokeWithParameter(paramString("t"));
System.out.println(1111);
return null;
}
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service; @Service
public class AsyncDemo { @Async
public void asyncInvokeWithParameter(String s) {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("asyncInvokeWithParameter, parementer={}"+ s);
} }
