Question

我使用的是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，我想配置类HibernateItemWriter的bean，就像这样：

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

但是在此版本的spring批处理中，不推荐使用类setHibernateTemplate的方法HibernateItemWriter。

/**
 * 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HibernateItemWriter：

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

我在弹出批处理作业执行时得到了这个例外：

你有解决方法吗？

看起来Spring Batch 2.2.0不支持Hibernate 3

谢谢

Answer 1

在发行说明中，截至Spring Batch 2.2.0;它似乎支持（默认情况下）Hibernate 4.参见：BATCH-1904 Upgrade support of Hibernate to Hibernate 4

在引用Hibernate 3

时使用3.6.2.RELEASE（使用org.springframework.batch.item.database.HibernateItemWriter测试）时，报告的错误将在运行时发生

要解决您的问题，请使用HibernateItemWriter的自定义实现。作为示例，请参阅Spring 2.1.9中此类的来源（请参阅HibernateItemWriter）;这与Hibernate 3兼容

Answer 2

试一试如果您正在使用maven：使用排除标记从spring-batch依赖项中排除hibernate.org包，让maven使用hibernate 3 deps构建您的应用程序。希望可以帮助

Spring批次2.2.0和Hibernate 3兼容
