public void beforeProcess(T item)
```
    从接口复制的说明: ItemProcessListener
    Called before ItemProcessor.process(Object).
    指定者:
    beforeProcess 在接口中 ItemProcessListener<T,S>
    参数:
    item - to be processed.
  - afterProcess
```
public void afterProcess(T item,
                         @Nullable
                         S result)
```
    从接口复制的说明: ItemProcessListener
    Called after ItemProcessor.process(Object) returns. If the processor returns null, this method will still be called, with a {code null} result, allowing for notification of 'filtered' items.
    指定者:
    afterProcess 在接口中 ItemProcessListener<T,S>
    参数:
    item - to be processed
    result - of processing
  - onProcessError
```
public void onProcessError(T item,
                           java.lang.Exception e)
```
    从接口复制的说明: ItemProcessListener
    Called if an exception was thrown from ItemProcessor.process(Object).
    指定者:
    onProcessError 在接口中 ItemProcessListener<T,S>
    参数:
    item - attempted to be processed
    e - - exception thrown during processing.
