如何在JSF中减少javax.faces.ViewState [英] How to reduce javax.faces.ViewState in JSF

推荐答案

您是否尝试过将状态保存设置为服务器？这应该只向客户端发送一个id，并保持服务器上的完整状态。只需将以下内容添加到文件 web.xml ：

Have you tried setting the state saving to server? This should only send an id to the client, and keep the full state on the server. Simply add the following to the file web.xml :

 <context-param>
  <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
  <param-value>server</param-value>
 </context-param>
