上面两种方式，只在 java project 下  弄起来过，servlet中 都没成功。

尝试方式：

　　1、servlet 直接 运行命令 "cmd /c shutdown -t 60" ==> 失败

　　2、bat 中写 shutdown，servlet 调用 bat ==> 失败

　　3、java project 中执行 shutdown，bat 调用 jar，servlet 调用 bat > 失败

 

 1 public String InputStream2String(InputStream _stream) throws Exception
 2     {
 3         String strRst = "";
 4         byte[] bytes = new byte[1024];
 5         while (_stream.read(bytes) != -1)
 6             strRst += new String(bytes);
 7         return strRst;
 8     }
 9 
10 InputStream2String
