package org.train.controller.filter;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;public class EncodingFilter implements Filter
{
protected FilterConfig filterConfig;
protected String encoding;

public void init(FilterConfig filterConfig)throws ServletException
{
this.filterConfig=filterConfig;
this.encoding=filterConfig.getInitParameter("Encoding");
}

public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain)throws IOException,ServletException
{
 if(request.getCharacterEncoding()==null)
 {
 String encode=getEncoding(request);
 if(encode!=null)
 {
request.setCharacterEncoding(encode);
response.setContentType("text/html; charset=GB2312");  
 }
 }
 chain.doFilter(request,response);
}

public void destroy()
{
filterConfig=null;
encoding=null;
}
private String getEncoding(ServletRequest request) 
{
return this.encoding;
}
}

Answer 6

所有page charset="GBK"String a = new String(request.getParameter("a").getBytes("iso-8859-1"),"GBK")

Answer 7

    <%@page contentType="text/html; charset=gb2312"%>
    <%response.setCharacterEncoding("GB2312");%> //传到另一个页面时，在传之前要写这一行代码。
String a = new String(request.getParameter("a").getBytes("iso-8859-1"),"GBK")
String a = new String(request.getParameter("a").getBytes("iso-8859-1"),"gb2312")//在接收页面时，接收时写这一段代码！保你没有问题！！

Answer 8

同一编码格式就行了，pageEncoding="gb2312"
如果用到struts2的话，在struts.xml中加<constant name="struts.i18n.encoding" value="GBK"/>
