关于调用javabean中所遇到的中文乱码问题

<%@ page contentType="text/html;charset=gb2312" language="java" %>
<jsp:useBean id="user" scope="page" class="com.Ts4Bean"/>
<jsp:setProperty name="user" property="*"/>
<%@ include file="trans.jsp"%>
<html>
<body>
提交成功： 
<hr>
使用bean属性方法： 
用户名：<%=session.getAttribute("name")%> 
班级：<%=user.getBanji()%> 
 
<hr>
</body>
</html> 代码如上
在班级这栏中调用的是前页的一个隐藏字段的值显示为乱码
请达人帮忙

Ｆilter实现版：
package filters;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.UnavailableException;
public class SetCharacterEncodingFilter implements Filter {
 protected String encoding = null;
 protected FilterConfig filterConfig = null;
 protected boolean ignore = true; public void destroy() { this.encoding = null;
 this.filterConfig = null; } public void doFilter(ServletRequest request, ServletResponse response,
 FilterChain chain)
 throws IOException, ServletException { // Conditionally select and set the character encoding to be used
 if (ignore || (request.getCharacterEncoding() == null)) {
 String encoding = selectEncoding(request);
 if (encoding != null)
 request.setCharacterEncoding(encoding);
 } // Pass control on to the next filter
 chain.doFilter(request, response); } public void init(FilterConfig filterConfig) throws ServletException { this.filterConfig = filterConfig;
 this.encoding = filterConfig.getInitParameter("encoding");
 String value = filterConfig.getInitParameter("ignore");
 if (value == null)
 this.ignore = true;
 else if (value.equalsIgnoreCase("true"))
 this.ignore = true;
 else if (value.equalsIgnoreCase("yes"))
 this.ignore = true;
 else
 this.ignore = false; } protected String selectEncoding(ServletRequest request) { return (this.encoding); }
}
配置web.xml
 <filter> <filter-name>Set Character Encoding</filter-name> <filter-class>filters.SetCharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>GBK</param-value> </init-param> </filter> <filter-mapping> <filter-name>Set Character Encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
在前一个页面中
<%@page pageEncoding="gbk"%>
charset=gb2312改成gbk，
然后用过滤器。这样，post提交的都没有问题。但如果你是get提交，就不行了。
get的话这样试试
1.new String(string.getBytes("GBK"), "UTF-8")
2.chi = java.net.URLEncoder.encode(chi, "ISO-8859-1");
            chi = java.net.URLDecoder.decode(chi, "GBK");
实在不行就编码，然后解码。
关于中文问题,请看下帖http://community.csdn.net/Expert/topic/5404/5404769.xml?temp=.9756739
我是include文件出现乱码，用了<%@page pageEncoding="gbk"%>很管用，谢谢啦
