Examples of LimitCheckingItemSkipPolicy

org.springframework.batch.core.step.skip.LimitCheckingItemSkipPolicy

{@link SkipPolicy} that determines whether or not reading should continuebased upon how many items have been skipped. This is extremely useful behavior, as it allows you to skip records, but will throw a {@link SkipLimitExceededException} if a set limit has been exceeded. Forexample, it is generally advisable to skip {@link FlatFileParseException}s, however, if the vast majority of records are causing exceptions, the file is likely bad.

Furthermore, it is also likely that you only want to skip certain exceptions. {@link FlatFileParseException} is a good example of an exception you willlikely want to skip, but a {@link FileNotFoundException} should causeimmediate termination of the {@link Step}. A {@link Classifier} is used todetermine whether a particular exception is skippable or not.
