方法详细资料

• getResource

  Resource getResource​(String location)

  Return a Resource handle for the specified resource location.

  The handle should always be a reusable resource descriptor, allowing for multiple InputStreamSource.getInputStream() calls.

  • Must support fully qualified URLs, e.g. "file:C:/test.dat".
  • Must support classpath pseudo-URLs, e.g. "classpath:test.dat".
  • Should support relative file paths, e.g. "WEB-INF/test.dat". (This will be implementation-specific, typically provided by an ApplicationContext implementation.)

  Note that a Resource handle does not imply an existing resource; you need to invoke Resource.exists() to check for existence.

  参数:

  location - the resource location

  返回:

  a corresponding Resource handle (never null)

• getClassLoader

  @Nullable
  ClassLoader getClassLoader()

  Expose the ClassLoader used by this ResourceLoader.

  Clients which need to access the ClassLoader directly can do so in a uniform manner with the ResourceLoader, rather than relying on the thread context ClassLoader.

  返回:

  the ClassLoader (only null if even the system ClassLoader isn't accessible)
