用java过滤器解决中文乱码

哎，今天终于明白，干什么事都他妈得细心，学java更得如此，Java对大小写要求，标点符号要求真他妈的严格。废话不多说了，写点我怎么解决的

1. 首先在你的工程中创建servlet，package为xiaogu ,name为EncodingFilter,然后把下边代码粘贴过去。

package xiaogu;

import java.io.IOException;

import java.io.PrintWriter;

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.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.util.*;

public class EncodingFilter extends HttpServlet implements Filter {

private FilterConfig filterConfig;

private String trargetEncoding=null;

public void init(FilterConfig filterConfig)throws ServletException{

this.filterConfig=filterConfig;

this.trargetEncoding=this.filterConfig.getInitParameter("encoding");

}

public void doFilter(ServletRequest request, ServletResponse response,

FilterChain filterChain) {

// TODO Auto-generated method stub

try{

//在控制台输出目标编码

System.out.println("trargetEncoding:"+trargetEncoding+"

");

//执行编码，实际的处理内容

request.setCharacterEncoding(trargetEncoding);

filterChain.doFilter(request,response);

}

catch (ServletException sx)

{

filterConfig.getServletContext().log(sx.getMessage());

}

catch (IOException iox){

filterConfig.getServletContext().log(iox.getMessage());

}

}

public void destroy() {

//清空资源

this.filterConfig=null;

this.trargetEncoding=null;

}

}

2.在web.xml中把下面的代码插到与中间，

encodingfilter

xiaogu.EncodingFilter//xiaogu为你的Java程序的包名，EncodingFilter是你的java的类名。

encode to UTF-8//UTF-8表示中文编码

encoding

UTF-8

encodingfilter

ok中文乱码问题全部解决。整了一下，分享给大家。
