刚才试了还是不好用

Answer 2

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？

Answer 3

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
