当我使用事务类型：RESOURCES_LOCAL时，它给出了以下错误：
只有事务类型为JTA的持久性单元才能用作容器管理实体管理器。
我的persistence.xml文件代码是：

答案 0 :(得分：0)
不，对于事务类型RESOURCE_LOCAL，您必须管理数据库交互而不是容器。
您可以通过@PersistenceUnit＆amp;注入EntityManagerFactory然后可以从中检索EntityManager。
所有数据库交易都将由您管理。无法通过EntityManager注入@PersistenceContext。
尝试浏览与 JTA，RESOURCE_LOCAL，CMT，BMT 等相关的文档，这将有助于更清楚地了解。
