JSP乱码问题，我刚研究过的，又出现了，这次解决不了了，大家帮忙看看怎么回事？
下面是我的JSP代码:
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=utf-8 ">
<title> ÎÞ±êÌâÎĵµ </title>
<style type= "text/css ">
<!--
.style1 {color: #EE0000}
-->
</style>
</head>
<body>
<h1 align= "center "> <span class= "style1 "> 学习网站后台管理系统 </span> </h1>
<h1> </h1>
</body>
</html>
只要一按“保存”就会出来对话框，下面是对话框提示：
“Save could not be completed
Ression:
Some characters cannot be mapped using "ISO-8859-1” character encoding either change the encoding or remove the characters which are not supported by the "ISO-8859-1 " character encoding. "
以前我遇到这个问题时，改一下文件属性“utf-8 "就行了，可是这次还是不行，怎么回事，请多指教呀？小弟感谢不尽，急呀。。。
------解决方案--------------------
<%
request.setCharacterEncoding( "gb2312 ")
%>
------解决方案--------------------
把这一句 <meta http-equiv= "Content-Type " content= "text/html; charset=utf-8 "> 去掉
把这一句 <%@page contentType= "text/html;charset=GB2312 "%> 放在文件头
------解决方案--------------------
涉及到字符编码的都换成utf-8
文件右击的properties中字符编码的设置也是utf-8
试试！
------解决方案--------------------
1.编码问题:
(1)首先确定JSP页面头部是否有: <%@ page contentType= "text/html; charset=GBK " %>
(2)类似这样的转码:
String param= new String(request.getParameter( "param ").getBytes( "ISO-8859-1 "), "GBK ");
(3)添加filter字符过滤器,具体做法:
先添加类:
import javax.servlet.Filter;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.FilterChain;
import java.io.IOException;
import org.apache.log4j.Logger;
import java.net.URLEncoder;
/** *//**
* 请求中中文字符串过滤类
*/
public class SetEncodingFilter
implements Filter ...{
private Logger logger=Logger.getLogger(this.getClass());
public void init(FilterConfig filterConfig) throws ServletException ...{
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException ...{
logger.info( "请求转码过滤器=================== ");
request.setCharacterEncoding( "gb2312 ");
chain.doFilter(request,response);
}
public void destroy() ...{
}
}
再注册类到XML里：
<fil
