DefaultItemFailureHandler (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.core.listener.ItemListenerSupport<java.lang.Object,java.lang.Object>
- - org.springframework.batch.core.step.item.DefaultItemFailureHandler

所有已实现的接口:
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.

    从接口复制的说明: ItemReadListener
    Called if an error occurs while trying to read.
    指定者:
    onReadError 在接口中 ItemReadListener<java.lang.Object>
    覆盖:
    onReadError 在类中 ItemListenerSupport<java.lang.Object,java.lang.Object>
    参数:
    ex - thrown from ItemWriter
  - onWriteError
```
public void onWriteError(java.lang.Exception ex,
                         java.util.List<? extends java.lang.Object> item)
```
    从接口复制的说明: ItemWriteListener
    Called if an error occurs while trying to write. Will be called inside a transaction, but the transaction will normally be rolled back. There is no way to identify from this callback which of the items (if any) caused the error.
    指定者:
    onWriteError 在接口中 ItemWriteListener<java.lang.Object>
    覆盖:
    onWriteError 在类中 ItemListenerSupport<java.lang.Object,java.lang.Object>
    参数:
    ex - thrown from ItemWriter
    item - attempted to be written.
