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)
