解决Tomcat中文文件名下载问题
本篇来源于：http://piggysnow.sinaapp.com/archives/29 我做下补充，记录一下[*]package com.utils;

[*] * 此类是为了解决 下载tomcat中的中文文件时连接错误的问题
[*] * 解决办法1(也是此类)：此类来源于网络：http://piggysnow.sinaapp.com/archives/29，需要注意的是在部署此项目的时候，需要把项目中的catalina.jar删除，否则会包冲突错误
[*] * 解决办法2：在tomcat中server.xml 大概70行的位置添加：URIEncoding="utf-8"

Web.xml配置一下servlet：
[*]
[*] chnURIServlet
[*] com.utils.DownloadCharacterEncodingServlet
[*]
[*]
[*] chnURIServlet
[*] /xls/*
[*]
需要注意的的是：要把那个jar包删除掉：不然会报如下错误：
