jsp與servlet中的中文問題

jsp頁面中一句話解決問題
<%@page contentType="text/html;charset=gb2312" language="java" %>
但是要使客戶提交的中文也行那就再來一句
<%request.setCharacterEncoding(”gb2312”);%>

但是不能解決直接手寫含中文的url連接到頁面，否則傳的參數會亂碼，也可以用String的構造方法試試。

servlet是我折騰了好一陣子的
也是一句話
    response.setContentType(”text/html;charset=gb2312”);效果等同jsp中的那句話
不過。。。。小心哦
它一定要加在 PrinterWriter out=response.getWriter();之前
否則你去抓狂吧，當然你還可以用

     String 的構造函數new String(srcString,"destination.encode");如：
     new String( demoString.getBytes(”這裏是源串編碼方式”,”iso-8859-1”)
這好像一直是救命稻草 換碼 哈哈這也是世界化的痛苦哦，但對於要求世界化來說真是福音。
     有人說把中文放在  .properties 文件中
      或許我沒做過大項目的緣故，從文件中讀所需的中文似乎不是很方便
      對於軟件的localization來說也許很有用
      就像c++中的資源文件
      還有一個很好的辦法不用每個文件都來句  request.setCharacterEncoding(”gb2312”),那就是filter（我用的tomcat)。寫一個服務器端過濾器就可以將所有的request編碼爲你想要的方式。這種方式同樣可以用於身份驗證，比如驗證訪問這個目錄的用戶是否已登陸，是否有權限，就不用要驗證的頁面都來個<%@ include file=”checker.jsp”%>了，真是好東西。還是放出我搜集的樣例代碼吧：
     

//title: filter for transform encoding method to gb2312
//Note:部署filter包含兩部分：指定類名、filter名及初始化參數；
//                           指定filter的映射及作用範圍（目錄）

        this.filterConfig=config;
        this.targetEncoding=config.getInitParameter("encoding");
        System.out.println("!!!!request is encoded in  "+targetEncoding);
    }
   
    //過濾功能在此處實現
    public void doFilter(ServletRequest req,ServletResponse res,FilterChain chain)
            throws IOException,ServletException{
               //follow line is for debug helping       
              //System.out.println("!!!!request is encoded in ** "+targetEncoding);
        HttpServletRequest request=(HttpServletRequest)req;
        request.setCharacterEncoding(this.targetEncoding);
             //turn the operation right to the next filter
        chain.doFilter(req, res);
    }
   
    public void serFilterConfig(final FilterConfig filterConfig){
        this.filterConfig=filterConfig;
    }
    public void destroy(){
        this.filterConfig=null;
    }
}
