characterencodingfilter.java

一个用户管理系统的例子,作的很好,有前端,有后台,增加,删除,修改,查找都可以实现

package com.allanlxf.ums.web;

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 CharacterEncodingFilter implements Filter
{
    private FilterConfig config;
    
    public void init(FilterConfig config) throws ServletException
    {        
        this.config = config;
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
    {
        String encoding = config.getInitParameter("encoding");
        if(encoding == null)
        {
            encoding = "gbk";
        }
        
        request.setCharacterEncoding(encoding);
        response.setCharacterEncoding(encoding);
        
        chain.doFilter(request, response);
    }

    public void destroy()
    {
    }
}
