Constructor Detail

ClassPathResourceLoader

public ClassPathResourceLoader()

Create a new DefaultResourceLoader.

ClassLoader access will happen using the thread context class loader at the time of this ResourceLoader's initialization.

See Also:

Thread.getContextClassLoader()

ClassPathResourceLoader

public ClassPathResourceLoader(java.lang.ClassLoader classLoader)

Create a new DefaultResourceLoader.

Parameters:

classLoader - the ClassLoader to load class path resources with, or null for using the thread context class loader at the time of actual resource access

Method Detail

setClassLoader

public void setClassLoader(java.lang.ClassLoader classLoader)

Specify the ClassLoader to load class path resources with, or null for using the thread context class loader at the time of actual resource access.

The default is that ClassLoader access will happen using the thread context class loader at the time of this ResourceLoader's initialization.

getClassLoader

public java.lang.ClassLoader getClassLoader()

Return the ClassLoader to load class path resources with, or null if using the thread context class loader on actual access (applying to the thread that constructs the ClassPathResource object).

Will get passed to ClassPathResource's constructor for all ClassPathResource objects created by this resource loader.

Specified by:

getClassLoader in interface ResourceLoader

Returns:

the ClassLoader (never null)

ClassPathResource

getResource

public Resource getResource(java.lang.String location)

Description copied from interface: ResourceLoader

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.

Specified by:

getResource in interface ResourceLoader

Parameters:

location - the resource location

Returns:

a corresponding Resource handle
