使用HibernateTemplate与Spring进行Hibernate Envers [英] Hibernate Envers with Spring using HibernateTemplate
问题描述
我正在尝试在Spring环境中设置Envers.当我从SessionFactory手动检索会话并将所有内容放入Transaction中时，一切工作正常:
I'm trying to setup Envers in a Spring environment. Everything works fine, when I retrieve a session manually from the SessionFactory and put everything inside a Transaction:
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
TestEntity test = new TestEntity();
test.setTest("REV1");
session.save(test);
tx.commit();
tx = session.beginTransaction();
test.setTest("REV2");
session.save(test);
tx.commit();
上面的代码将数据插入到TestEntity表中，还更新了AUD表和REVINFO表.
The above code inserts data into the TestEntity-table and also updates the AUD- and REVINFO-tables.
但是，当我使用DAO更新表时，特定于Envers的表没有任何反应.我怀疑原因可能是在DAO中使用HibernateTemplate 使用HibernateTemplate .
However, when I update the table using our DAO, nothing happens to the Envers-specific tables. I suspect the reason might be using HibernateTemplate in the DAO.
HibernateDaoSupport dao;
...
HibernateTemplate hibernateTemplate = dao.getHibernateTemplate();
TestEntity test = new TestEntity();
test.setTest("REV1");
hibernateTemplate.saveOrUpdate(test);
test.setTest("REV2");
hibernateTemplate.saveOrUpdate(test);
我的SessionFactory的Spring配置如下:
My Spring-config for the SessionFactory looks like this:
<bean id="test-sessionFactory" class=...>
<property name="dataSource" ref="test-dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="eventListeners">
<map>
<entry key="post-insert" value-ref="enversListener" />
<entry key="post-update" value-ref="enversListener" />
<entry key="post-delete" value-ref="enversListener" />
<entry key="pre-collection-update" value-ref="enversListener" />
<entry key="pre-collection-remove" value-ref="enversListener" />
<entry key="post-collection-recreate" value-ref="enversListener" />
</map>
</property>
</bean>
我已经阅读了很多论坛和博客文章，包括此一个，该链接与Envers常见问题解答中的链接有关，但在我的情况下似乎没有任何提及.
I have read quite a lot of forum- and blog entries including this one, that is linked to from the Envers FAQ, but nothing mentioned there seems to work in my situation.
有人知道，是否有可能使用HibernateTemplate(而不是JPA)将Envers配置为与Spring一起使用?我需要更改配置的哪些部分?在这种情况下，Hibernate文档/API的哪一部分值得研究(恐怕我还不是Hibernate专家)?有人可以提供工作配置的代码示例吗?
Does anyone know, if it's possible to configure Envers to work together with Spring using HibernateTemplate (instead of JPA)? What parts of my configuration do I need to change? What part of the Hibernate documentation/API is worth looking at in this context (I'm afraid I'm not an Hibernate expert yet)? Could someone provide a code sample of a working configuration?
我正在使用Spring 3.0.1和Hibernate 3.5.1.
I'm using Spring 3.0.1 and Hibernate 3.5.1.
推荐答案
问题是由以下事实引起的:Envers依赖正确的事务管理，而HibernateTemplate在事务之外使用时退回到自动提交"模式，因此Envers在这种情况下不起作用.
The problem is caused by the fact that Envers relies on proper transaction management, whereas HibernateTemplate falls back to "auto-commit" mode when used outside of transaction, so that Envers doesn't work in this case.
因此，您需要配置事务管理才能使用Envers.在事务内调用HibernateTemplate的方法时，Envers可以正常工作.
Therefore you need to configure transaction management in order to use Envers. When HibernateTemplate's methods are called inside a transaction, Envers works fine.
