Java 如何将具有异步方法调用行为的bean添加到liferay portlet？

我运行Liferay 6.2 CE。我试图声明一个bean，该bean的方法可以异步调用。但当我调用该方法时，它会同步执行。所以我不明白，我错过了什么

这是我的豆子：

public class MyBean {

    @Async
    public void process(){
        try {
            Thread.sleep(10000L);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println(new Date());
    }
}

我已将Spring注释添加到我的项目依赖项中：

...
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>3.0.7.RELEASE</version>
</dependency>
...

您可以共享调用process（）方法的代码段吗？@premkumar，我已经共享了代码段。很可能，我应该直接使用

ThreadPoolTaskExecutor

。
