为什么使用getRequestDispatcher转向新的地址后网页乱码?

[小王]

我用request.getRequestDispatcher(target).forward(request, response);转向一个新地址后,中文字符乱码,相同的页面如果用response.sendRedirect就没有问题.

[hbzyduwu]

response.setCharacteEncoding("gb2312");

----------------------------------------------------------------------
response.setCharacteEncoding("gb2312");

刚才试了还是不好用

中文处理一下

问题解决了但是有一点不明白我的源码如下
package com.framework;

import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class MainServlet
extends HttpServlet {
//处理Get请求
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
this.doProcess(request, response);
}

//处理Post请求
public void doPost(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
this.doProcess(request, response);
}

//
public void doProcess(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
request.setCharacterEncoding("ISO-8859-1");
//PrintWriter out = response.getWriter();
request.getRequestDispatcher("0001.jsp?page=2").forward(request, response);
}
}
当我把PrintWriter out = response.getWriter();这行注释掉就不乱码了，这是什么原因呢？

PrintWriter out = response.getWriter();我重来不用？这是干吗的？汗~~~

这句对于你的程序没用,是要显示实质性内容用的，比如要在页面上显示数据和html元素等
