public class ClassPathXmlApplicationContext
extends AbstractXmlApplicationContext

Standalone XML application context, taking the context definition files from the class path, interpreting plain paths as class path resource names that include the package path (e.g. "mypackage/myresource.txt"). Useful for test harnesses as well as for application contexts embedded within JARs.

The config location defaults can be overridden via AbstractRefreshableConfigApplicationContext.getConfigLocations(), Config locations can either denote concrete files like "/myfiles/context.xml" or Ant-style patterns like "/myfiles/*-context.xml" (see the AntPathMatcher 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.

This is a simple, one-stop shop convenience ApplicationContext. Consider using the GenericApplicationContext class in combination with an XmlBeanDefinitionReader for more flexible context setup.

Method Details

getConfigResources

@Nullable
protected Resource[] getConfigResources()

Description copied from class: AbstractXmlApplicationContext

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

Overrides:

getConfigResources in class AbstractXmlApplicationContext

Returns:

an array of Resource objects, or null if none
