Method Detail

getResource

Resource getResource(java.lang.String location)

Return a Resource handle for the specified resource. 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.

Parameters:

location - the resource location

Returns:

a corresponding Resource handle

CLASSPATH_URL_PREFIX, Resource.exists(), InputStreamSource.getInputStream()

getClassLoader

java.lang.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.

Returns:

the ClassLoader (never null)
