在jsp中，中文亂碼常會讓人心亂如麻。一般的解決方案
一、本頁顯示問題
"<%@ page contentType="text/html;charset=GB2312"%>"
二、提交問題
鑒於此問題，你可以將讀出來的字串進行轉換，這很簡單：
str = request.getParameter("s");
str = new String(str.getBytes("ISO-8859-1"),"GBK");
或者設定
request.setCharacterEncoding("GBK");
然而，你遇到這種情況嗎，使用out.println是中文，Systemout.println是亂碼，看下面的例子
jsp1.jsp建立
<%@ page contentType="text/html;charset=GB2312"%>
<html>
<head>
<title>
mm
</title>
</head>
<body background="">
<form method="POST" action="servlet1">
<input type="text" name="myt" size="30" value =" ">
<br>
<input type="text" name="myedit" size="30" value ="">
<input type="submit" value="保 存" name="B5" >
</form>
</body>
</html>
-----
servlet1 建立
package untitled2;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class Servlet1 extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
{
response.setContentType("text/html;charset=GBK") ;
request.setCharacterEncoding("GBK");
PrintWriter out = response.getWriter() ;
out.println(request.getParameter("myedit"));
System.out.println(request.getParameter("myedit"));
}
}
編譯後在ie運行，myedit中輸入漢字，就會出現我說亂碼，可別小看，對你有用System.out.println的輸出，本人經過反覆的調試，發現將
<input type="text" name="myt" size="30" value =" ">中" "修改為""，就沒有問題了。" "我們經常用就是空，到底是什麼問題導致，我還不清楚。
我用的jbuild7.0,jdevelop9.03都有此問題。
