Method Details
-
beforeChunk
Callback before the chunk is executed, but inside the transaction.- Parameters:
context
- The currentChunkContext
-
afterChunk
Callback after the chunk is executed, outside the transaction.- Parameters:
context
- The currentChunkContext
-
afterChunkError
Callback after a chunk has been marked for rollback. It is invoked after transaction rollback. While the rollback will have occurred, transactional resources might still be active and accessible. Due to this, data access code within this callback will still "participate" in the original transaction unless it declares that it runs in its own transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.- Parameters:
context
- the chunk context containing the exception that caused the underlying rollback.
