SpringBatch batch framework --- Chunk interceptor

Chunk operation provides a wealth of interceptor mechanism, interceptor additional control capability can be achieved, such as logging, task tracking, status reporting capabilities, data transfer, etc.,

In the process SpringBatch in, keep it simple business as much as possible, the need for any additional processing functions implemented in the interceptor

                                                               Chunk Interceptor Interface

 Chunk interceptor scope:                              

     JobExecutionListener                           

   StepExecutionListener                       

         Tasklet                                           

         ChunkListner                                 

  ItemReadListener                                   

  ItemProcessListener

 ItemWriteListener

Chunk interceptor implementation of the order:

JobExecutionListener .beforeJob()

StepExecutionListener.beforeStep()

ChunkListener.beforeChunk()

ItemReadListener.beforeRead()

ItemReadListener.afterRead()

ItemProcessListener.beforeProcess()

ItemProcessListener.afterProess()

ItemWriteListener.beforeWrite()      

ItemWriteListener.afterWrite()

ChunListener.afterChunk()

StepExecutionListener.afterStep()

 JobExecutionListener .afterJob()
