我正在练习一个使用 spring、hibernate 库和 Weblogic JTA 平台作为 JTA 事务管理器的 Web 应用程序，该应用程序已成功部署在 Oracle weblogic 12c Server 上。当我尝试使用 Hibernate DAO 执行任何数据库操作时，我收到以下错误

请帮帮我，我已经为此苦苦挣扎了很长时间。
提前致谢.!!
最佳答案
我找到了问题的解决方案，我在 spring 的 applicationContext.xml 中缺少 tx:annotationDriven 元素。添加该元素启动了 Spring aop 启用的事务管理，它使用 WeblogicJtaTransactionManager 来管理事务隐式..!!
关于java - 由 : javax. persistence.TransactionRequiredException 引起:在带有 Spring JTA 事务的 Weblogic 上，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50208203/
