java - JPA + Hibernate + 自动提交

Question

有人知道为什么我在 JPA 配置文件中关闭自动提交时会收到此警告吗？

使用此设置:

<property name="hibernate.connection.autocommit" value="false"/>

生成此警告:

2009-08-04 09:54:10,621 [main] WARN org.hibernate.ejb.Ejb3Configuration - hibernate.connection.autocommit = false break the EJB3 specification

这会如何破坏 EJB3 规范？

来自 EJB 3.0 规范的第 13.3.4 节:

The enterprise bean’s business methods, message listener methods, business method interceptor methods,life cycle call back interceptor methods, or timeout callback method must not use any resource-manager specific transaction management methods that would interfere with the container’s demarcation of transaction boundaries. For example, the enterprise bean methods must not use the following methods of the java.sql.Connection interface:commit, setAutoCommit, and rollback; or the following methods of the javax.jms.Session interface:commit and rollback.
