  org.springframework.batch.core.configuration.support.AutomaticJobRegistrar

All Implemented Interfaces:

java.util.EventListener, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener, org.springframework.context.Lifecycle, org.springframework.core.Ordered

public class AutomaticJobRegistrar
extends java.lang.Object
implements org.springframework.core.Ordered, org.springframework.context.Lifecycle, org.springframework.context.ApplicationListener, org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.InitializingBean

Loads and unloads Jobs when the application context is created and destroyed. Each resource provided is loaded as an application context with the current context as its parent, and then all the jobs from the child context are registered under their bean names. A JobRegistry is required.
