Spring Batch 2.2.0和Hibernate 3的兼容性问题

Question

我正在使用Spring Batch的2.2.0版本和Hibernate的3.6.4版本。在我的基于Java的Spring配置中，我想要像这样配置我的HibernateItemWriter类的bean：

@Bean
public <E> ItemWriter<E> hibernateItemWriter(HibernateOperations hibernateTemplate) {
    HibernateItemWriter<E> writer = new HibernateItemWriter<E>();
    writer.setHibernateTemplate(hibernateTemplate);
    return writer;
}

但是在这个版本的Spring Batch中，类HibernateItemWriter的方法setHibernateTemplate已经被弃用。

/**
 * Public setter for the {@link HibernateOperations} property.
 *
 * @param hibernateTemplate
 *            the hibernateTemplate to set
 * @deprecated As of 2.2 in favor of using Hibernate's session management APIs directly
 */
public void setHibernateTemplate(HibernateOperations hibernateTemplate) {
    this.hibernateTemplate = hibernateTemplate;
} 

我尝试按照以下方式配置我的HibernateItemWriter：

@Bean
public <E> ItemWriter<E> hibernateItemWriter(SessionFactory sessionFactory) {
    HibernateItemWriter<E> writer = new HibernateItemWriter<E>();
    writer.setSessionFactory(sessionFactory);
    return writer;
}

我在Spring Batch Job执行过程中遇到了这个异常:

你有解决这个问题的方案吗？

似乎Spring Batch 2.2.0不支持Hibernate 3

谢谢

Answer 1

发布说明中，从 Spring Batch 2.2.0 开始，默认支持 Hibernate 4。参见：BATCH-1904 Upgrade support of Hibernate to Hibernate 4

使用 HibernateItemWriter 引用 org.springframework.batch.item.database.HibernateItemWriter，当运行时使用 Hibernate 3（已测试使用 3.6.2.RELEASE）时，将出现报告的错误

为解决问题，请使用自定义实现 HibernateItemWriter，可参考 Spring 2.1.9 中此类的源代码（参见HibernateItemWriter），该实现与 Hibernate 3 兼容。

Answer 2

仅仅是一次尝试。如果你正在使用Maven，请使用排除标签从spring-batch依赖中排除hibernate.org包，以便让Maven构建您的应用程序与hibernate 3依赖项。希望能够帮助到您。
