Java-很深我只知其一-路径获取/处理

  • request对象获取发布容器的跟路径
  • 括号内可以指定具体包名,获取路径以包名为单位
request.getSession().getServletContext().getRealPath("/")

 

  • 获取以该类为基准的绝对路径,可以循环/截取保留自己所需要的部分

当前类.class.getResource( "/" ).toURI().getPath();
  • 如果返回对象为null值 ,去掉toURI层就好
当前类.class.getResource( "/" ).getPath();

 

 

 

  • 获取当前项目所在位置根目录(当前项目所在工作空间工作空间)
String path = System.getProperty("user.dir")
  • 很多时候,文件获取失败是间隔符的识别问题
  • win中\\ 而linux / java跨平台性特别强,File.separator做通配间隔符,能减少很多麻烦

 

随笔记录,只为方便自己学习
