1、過載ActionServlet

package com.xtu.overrid;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionServlet;

public class OverridActionServlet extends ActionServlet{
 protected void process(HttpServletRequest request,
   HttpServletResponse response) throws IOException, ServletException {
  request.setCharacterEncoding("UTF-8");
  super.process(request, response);
 }
}

2、在Web.xml中修改成如下配置

<servlet-name>action</servlet-name>
  <!--
   <servlet-class>
   org.apache.struts.action.ActionServlet
   </servlet-class>
  -->

  <servlet-class>
   com.xtu.overrid.OverridActionServlet
  </servlet-class>

如果你的資料庫是Oracle，那麼上面的這些配置就可以解決問題。

但是如果資料庫是MySQL就有可能還要:

1、修改你的資料庫的編碼改為gb2312

2、把你的資料庫驅動改成最新的，如mysql-connector-java-3.1.13-bin
