Chapter 12. JSR-352 Support

Spring Batch and JSR-352 are structurally the same. They both have jobs that are made up of steps. They both have readers, processors, writers, and listeners. However, their interactions are subtly different. For example, the org.springframework.batch.core.SkipListener#onSkipInWrite(S item, Throwable t) within Spring Batch receives two parameters: the item that was skipped and the Exception that caused the skip. The JSR-352 version of the same method (javax.batch.api.chunk.listener.SkipWriteListener#onSkipWriteItem(List<Object> items, Exception ex)) also receives two parameters. However the first one is a List of all the items within the current chunk with the second being the Exception that caused the skip. Because of these differences, it is important to note that there are two paths to execute a job within Spring Batch: either a traditional Spring Batch job or a JSR-352 based job. While the use of Spring Batch artifacts (readers, writers, etc) will work within a job configured via JSR-352's JSL and executed via the JsrJobOperator, they will behave according to the rules of JSR-352. It is also important to note that batch artifacts that have been developed against the JSR-352 interfaces will not work within a traditional Spring Batch job.
