spring-@Async标签使用

 一、打上标签

@Resource
private AsyncSendTest asyncSendTest;

@Test
public void testAsyncSend(){
System.out.println("异步调用开始");
asyncSendTest.doSomething();
System.out.println("异步调用结束");
}

@Service
public class AsyncSendTest {

@Async
public void doSomething(){
System.out.println("异步处理中....");
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("异步处理结束");
}
}

===========输出结果：============

异步调用开始
异步处理中....
异步处理结束
异步调用结束

 

二、配置spring task executor

<beans  增加 ：xmlns:task="http://www.springframework.org/schema/task"

                     xsi:schemaLocation="http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd"/>

<task:executor id="executor" pool-size="10"/>
<task:annotation-driven executor="executor" proxy-target-class="true"/>

异步调用开始
异步调用结束
异步处理中....
异步处理结束
