org.springframework.batch.repeat.exception.LogOrRethrowExceptionHandler

All Implemented Interfaces:

setExceptionClassifier

public void setExceptionClassifier(org.springframework.classify.Classifier<Throwable,LogOrRethrowExceptionHandler.Level> exceptionClassifier)

Setter for the Classifier used by this handler. The default is to map all throwable instances to LogOrRethrowExceptionHandler.Level.RETHROW.

Parameters:

exceptionClassifier - the ExceptionClassifier to use

handleException

public void handleException(RepeatContext context,
 Throwable throwable)
                     throws Throwable

Classify the throwables and decide whether to rethrow based on the result. The context is not used.

Specified by:

handleException in interface ExceptionHandler

Parameters:

context - the current RepeatContext. Can be used to store state (via attributes), for example to count the number of occurrences of a particular exception type and implement a threshold policy.

throwable - an exception.

Throws:

Throwable - thrown if exceptionClassifier is classified as LogOrRethrowExceptionHandler.Level.RETHROW.
