RepeatListenerSupport
public RepeatListenerSupport()
方法详细资料
before
public void before(RepeatContext context)
从接口复制的说明:RepeatListener
Called by the framework before each batch item. Implementers can halt a batch by setting the complete flag on the context.- 指定者:
before
在接口中RepeatListener
- 参数:
context
- the current batch context.
after
public void after(RepeatContext context, RepeatStatus result)
从接口复制的说明:RepeatListener
Called by the framework after each item has been processed, unless the item processing results in an exception. This method is called as soon as the result is known.- 指定者:
after
在接口中RepeatListener
- 参数:
context
- the current batch contextresult
- the result of the callback
close
public void close(RepeatContext context)
从接口复制的说明:RepeatListener
Called once at the end of a complete batch, after normal or abnormal completion (i.e. even after an exception). Implementers can use this method to clean up any resources.- 指定者:
close
在接口中RepeatListener
- 参数:
context
- the current batch context.
onError
public void onError(RepeatContext context, java.lang.Throwable e)
从接口复制的说明:RepeatListener
Called when a repeat callback fails by throwing an exception. There will be one call to this method for each exception thrown during a repeat operation (e.g. a chunk).
There is no need to re-throw the exception here - that will be done by the enclosing framework.- 指定者:
onError
在接口中RepeatListener
- 参数:
context
- the current batch contexte
- the error that was encountered in an item callback.
open
public void open(RepeatContext context)
从接口复制的说明:RepeatListener
Called once at the start of a complete batch, before any items are processed. Implementers can use this method to acquire any resources that might be needed during processing. Implementers can halt the current operation by setting the complete flag on the context. To halt all enclosing batches (the whole job), the would need to use the parent context (recursively).- 指定者:
open
在接口中RepeatListener
- 参数:
context
- the current batch context
