The
ValidatingItemProcessor
is useful for being able to apply validation to your items as they are
processed. However, it is only one of the three implementations of the ItemProcessor interface provided
by Spring Batch. In the next section you will look at the ItemProcessorAdapter and how it allows you to
use existing services as ItemProcessors.
ItemProcessorAdapter
In Chapter 7, you looked at the ItemReaderAdapter as a way to use existing services to provide input to
your jobs. Spring Batch also allows you to put to use the various services you already have developed as
ItemProcessors as well by using the
org.springframework.batch.item.adapter.ItemProcessorAdapter
.
