getClass().getClassLoader().getResource() 和 getClass().getResource()

A two effects:

在java中加载文件

II. Difference between the two

• . .GetClass () getResource (fileName): fileName represents only looks for the file in the same directory where the current call class;

• .. .GetClass () getClassLoader () getResource (fileName): represents only find the file in the root directory (/);

• fileName if it is preceded by "/", such as "/ fileName", said absolute path, taken / the files in the directory;
  if it is not preceded by "/", such as "fileName" indicates a relative path, taking the call the files in the same class path.

• If the path name contains the package, getClass () getResource ( "com / xxx / 1.xml");.
  Hierarchy using the package name "/" spaced (forward slash), rather than "."
