类 HibernateItemWriter<T>

  • 所有已实现的接口:
    ItemWriter<T>, org.springframework.beans.factory.InitializingBean
    public class HibernateItemWriter<T>
extends java.lang.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.

        指定者:
        afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean

      • write

        public void write​(java.util.List<? extends T> items)
        Save or update any entities not in the current hibernate session and then flush the hibernate session.
