我尝试使用hibernate方法保存用户persist。 我运行我的测试方法后，我得到一个异常。我查了同样的问题很多话题，比如添加@Transactional的类，检查春季版本等，但它仍然有此异常Hibernate Spring JPA javax.persistence.TransactionRequiredException：没有事务性的EntityManager可用

你的建议是非常有益的！ 现在有用，谢谢！ –
我看了很多教程，并没有关于这个注释。我是jpa的新手，你能用几句话来解释我为什么没有它就无法工作？ –
嗨，有两种配置方法来设置弹簧数据：基于注释和基于xml。 – BugProtectionActivist
