读取docx文档中的姓名并重命名文档
需要用到的框架，poi，把下载的zip内所有的jar引用到项目中。
代码如下：

File tmp = new File("/Users/ge.su/Desktop/2018年度工作互评表.docx");
System.out.println("is dir "+tmp.isDirectory());
System.out.println("is file "+tmp.isFile());
*/
// 获取到的路径带..,getAbsolutePath也带,getCanonicalPath会转换成/sdcard/test
// File tp = new File("/sdcard/Download/../test");
