org.springframework.batch.repeat.exception

Interface ExceptionHandler

All Known Implementing Classes:

CompositeExceptionHandler, DefaultExceptionHandler, FootballExceptionHandler, LogOrRethrowExceptionHandler, RethrowOnThresholdExceptionHandler, SimpleLimitExceptionHandler, SimpleRetryExceptionHandler

public interface ExceptionHandler

Handler to allow strategies for re-throwing exceptions. Normally a CompletionPolicy will be used to decide whether to end a batch when there is no exception, and the ExceptionHandler is used to signal an abnormal ending - an abnormal ending would result in an ExceptionHandler throwing an exception. The caller will catch and re-throw it if necessary.
