如何将欢迎页面设置为struts操作？ [英] How can I set the welcome page to a struts action?

问题描述

我有一个基于struts的webapp，我希望默认的欢迎页面是一个动作。我发现的唯一解决方案似乎是使欢迎页面成为包含重定向到操作的JSP的变体。例如，在 web.xml 中：

I have a struts-based webapp, and I would like the default "welcome" page to be an action. The only solutions I have found to this seem to be variations on making the welcome page a JSP that contains a redirect to the action. For example, in web.xml:

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

和 index.jsp ：

<% 
  response.sendRedirect("/myproject/MyAction.action");
%> 

肯定有更好的方法！

推荐答案

就个人而言，我会保持现在的设置，但更改前进的重定向。这样可以避免向客户端发回标题并让他们再次发出请求。

Personally, I'd keep the same setup you have now, but change the redirect for a forward. That avoids sending a header back to the client and having them make another request.

所以，特别是，我要替换

So, in particular, I'd replace the

<% 
  response.sendRedirect("/myproject/MyAction.action");
%>

in index.jsp with

in index.jsp with

<jsp:forward page="/MyAction.action" />

此更改的另一个影响是用户不会看到地址栏中的URL更改从 http：// server / myproject 到 http：//server/myproject/index.jsp ，因为转发在服务器内部发生。

The other effect of this change is that the user won't see the URL in the address bar change from "http://server/myproject" to "http://server/myproject/index.jsp", as the forward happens internally on the server.
