public class ClassPathXmlApplicationContext

extends AbstractXmlApplicationContext

Standalone XML application context, taking the context definition files from the class path. Mainly useful for test harnesses, but also for application contexts embedded within JARs.

Treats resource paths as class path resources, when using getResource. Only supports full class path resource names that include the package path, like "mypackage/myresource.dat".

The config location defaults can be overridden via setConfigLocations, Config locations can either denote concrete files like "/myfiles/context.xml" or Ant-style patterns like "/myfiles/*-context.xml" (see PathMatcher javadoc for pattern details).

Note: In case of multiple config locations, later bean definitions will override ones defined in earlier loaded files. This can be leveraged to deliberately override certain bean definitions via an extra XML file.

Method Detail

getConfigLocations

protected String[] getConfigLocations()

Description copied from class: AbstractXmlApplicationContext

Return an array of resource locations, referring to the XML bean definition files that this context should be built with.

Can also include location patterns, which will get resolved via a ResourcePatternResolver.

Specified by:

getConfigLocations in class AbstractXmlApplicationContext

Returns:

an array of resource locations, or null if none
