Class JobConfigurationResourceLoader

java.lang.Object
  org.springframework.batch.admin.integration.JobConfigurationResourceLoader

All Implemented Interfaces:

ApplicationContextAware

@MessageEndpoint
public class JobConfigurationResourceLoader
extends Object
implements ApplicationContextAware

Load XML from a Spring Resource and create an ApplicationContext, registering any Job instances defined in a JobRegistry. If this component is itself configured with Spring, then its own ApplicationContext will be the parent for the new one, and the child will inherit AOP configuration, as well as property placeholder and custom editor configuration from the parent.
