tomcat6 打开中文资源的有关问题

tomcat6 打开中文资源的问题
http://localhost:8080/ebook/中文说明.pdf

中文说明.pdf
在tomcat6的ebook的web目录下的，
也就是项目录 下的资源，
现在想直接点击链接打开，
但是因为中文名字的问题
因为文件名是由客户定义的所以这个问题还是会出现的，


[解决办法]
添加一个过滤器试试看：

Java code

package com.test;import java.io.IOException;import java.net.URLDecoder;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.HttpServletRequest;public class UrlFilter implements Filter {    public final static String DEFAULT_URI_ENCODE = "UTF-8";        private FilterConfig config = null;    private String encode = null;        @Override    public void init(FilterConfig config) throws ServletException {        this.config = config;        this.encode = config.getInitParameter("DEFAULT_URI_ENCODE");        if(this.encode == null) {            this.encode = DEFAULT_URI_ENCODE;        }    }    @Override    public void doFilter(ServletRequest req, ServletResponse res,            FilterChain chain) throws IOException, ServletException {        HttpServletRequest request = (HttpServletRequest) req;        String uri = request.getRequestURI();        String ch = URLDecoder.decode(uri, encode);        if(uri.equals(ch)) {            chain.doFilter(req, res);            return;        }        ch = ch.substring(request.getContextPath().length());        config.getServletContext().getRequestDispatcher(ch).forward(req, res);    }        @Override    public void destroy() {        config = null;    }}
