功能：这是一个网页版的文件批量重命名
操作步骤：
输入文件所在的绝对路径，
输入你想要替换的关键字，
输入你想要用什么字符来替换他（可为空），
点击确定，文件将会批量被重命名，
点击撤回就会还原出起初的文件名字，
点击清空主要是一键清除文本框里面的内容。
总的有1个jsp，四个Java程序共同完成这个功能：
start.jsp(显示界面)
CodeFilter.java(过滤器，主要负责编码)
ReceiveStartServlet.java(接受启动，进行文件操作)
RevokeServlet.java(撤回操作Servlet)
ClearServlet.java(清空操作)
未操作前图：
运行start.js的效果图：
运行后文件显示图：
start.jsp代码：
