问题描述

我需要做以下事情:

1. 用户登录.
2. 重定向到欢迎屏幕.
3. 在加载大量记录时查看欢迎屏幕.
4. 重定向到工作屏幕.

我正在寻找一种在 Action 类中执行以下操作的方法:

I am looking for a way to do in Action class something like this:

public class LinkAction extends ActionSupport implements SessionAware {
        @Autowired
        private ServiceDelegate myService;

    public String welcome()
        {
            new Runnable() {
                @Override
                public void run() {
                    myService.getLoadsOfData();

                    //redirect to the next action

                }
            }.run();
            // this is where the user 
            // goes to look at the welcome screen        
            return "welcome";
        }
    }

可能这是一个错误的方法，如果是，请告诉我，我是 Struts 的新手.

May be it's a wrong approach, please tell if so, I am new at Struts.

推荐答案

感谢 AJAX 的想法.

Thank you for the AJAX idea.

然而，我正在寻找的答案实际上是 Struts 拦截器execAndWait".我决定在 AJAX 上使用它，因为我正在处理现有的应用程序并且所有的 Struts 管道都已就位.这是 Struts 指南

However, the answer I was looking for was in fact Struts interceptor "execAndWait". I decided to use it over AJAX because I am dealing with existing application and all the Struts plumbing is in place. This is the Struts guide on this
