- All Implemented Interfaces:
ItemWriter<T>
,org.springframework.beans.factory.InitializingBean
public class HibernateItemWriter<T>
extends Object
implements ItemWriter<T>, org.springframework.beans.factory.InitializingBean
ItemWriter
that uses a Hibernate session to save or update entities
that are not part of the current Hibernate session. It will also flush the
session after writing (i.e. at chunk boundaries if used in a Spring Batch
TaskletStep). It will also clear the session on write
default (see clearSession
property).The writer is thread-safe once properties are set (normal singleton behavior) if a
CurrentSessionContext
that uses only one session per thread is
used.- Author:
