让JAVA应用服务器支持中文URL路径

　　Tomcat等JAVA应用服务器，默认情况下是不支持中文的URL访问路径的，我们可以通过自己添加滤镜的方法让其支持，具体代码如下：

package com.suntek.draw.common;

import javax.servlet.*;

import java.io.*;

import javax.servlet.http.*;

import java.net.*;

public class DwfFilter implements Filter {

    protected FilterConfig filterConfig = null;

    private String encoding = null;

   

    public void destroy() {

        filterConfig = null;

        encoding = null;

    }

    /**

     * 让Tomcat支持中文路径。

     * @param request ServletRequest

     * @param response ServletResponse

     * @param chain FilterChain

     * @throws IOException

     * @throws ServletException

     */

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,

        ServletException {

        HttpServletRequest req = (HttpServletRequest) request;

        String s = req.getRequestURI();

        String url = URLDecoder.decode(s, encoding); //当IE中Intertnet选项-高级选项-总是以UTF-8发送URL 被选中时。

        String context = req.getContextPath();

        if ((url !=null) && (context !=null)){

            int idx = url.indexOf(context);

            if (idx>=0){

                url = url.substring(idx+context.length());

            }

        }

        filterConfig.getServletContext().getRequestDispatcher(url).forward(req,response);

    }

    public void init(FilterConfig filterConfig) throws ServletException {

        this.filterConfig = filterConfig;

        encoding = filterConfig.getInitParameter("encoding");

    }

}

在Web.XML文件中添加此滤镜即可。

<filter>

    <filter-name>DWFFilter</filter-name>

    <filter-class>com.suntek.draw.common.DwfFilter</filter-class>

    <init-param>

      <param-name>encoding</param-name>

      <param-value>UTF-8</param-value>

    </init-param>

  </filter>
