Class DefaultItemFailureHandler

java.lang.Object

org.springframework.batch.core.listener.ItemListenerSupport<java.lang.Object,java.lang.Object>

org.springframework.batch.core.step.item.DefaultItemFailureHandler

All Implemented Interfaces:

ItemProcessListener<java.lang.Object,java.lang.Object>, ItemReadListener<java.lang.Object>, ItemWriteListener<java.lang.Object>, StepListener

public class DefaultItemFailureHandler
extends ItemListenerSupport<java.lang.Object,java.lang.Object>

Default implementation of the ItemListenerSupport class that writes all exceptions via commons logging. Since generics can't be used to ensure the list contains exceptions, any non exceptions will be logged out by calling toString on the object.
