Servlet之间重定向传参出现中文乱码要怎么解决？？？

public class ReqeustScope1 extends HttpServlet {
   public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        request.setCharacterEncoding("GBK");
        response.setCharacterEncoding("GBK");
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
                String sex = "男";
        String url = "/servlet/RequestScope2?sex=" + sex;

        response.sendRedirect(context + url);

        out.flush();
        out.close();
    }
}

public class RequestScope2 extends HttpServlet {
  public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        request.setCharacterEncoding("GBK");
        response.setCharacterEncoding("GBK");
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        System.out.println(" =====:" + request.getParameter("sex"));
        out.flush();
        out.close();
    }
}

在RequestScope2中输出的就不是中文了 这个要怎么解决

不是很好的解决办法：

1、在RequestScope中修改URL
[code="java"]String url = "/web/servlet/RequestScope2?sex=" + URLEncoder.encode(sex,"GBK"); [/code]

2、在RequestScope2中，这样取得参数值：
[code="java"]String[] queryStrings =request.getQueryString().split("&");
String key ;
String value ;
for(String queryString : queryStrings){
key = queryString.split("=")[0];
value = queryString.split("=")[1];

        value = URLDecoder.decode(value,"GBK");
        System.out.println(key+" : "+value);
    }[/code]

建议还是不要用中文的好，不然处理很麻烦。[/b]
