@Transactional 即使使用编译时编织插件也会抛出 TransactionRequiredException 与 ASPECTJ ？

Question

@Transactional 抛出 TransactionRequiredException：没有可用于当前线程的实际事务的 EntityManager - 无法可靠地处理持久性 使用 AspectJ 时，即使安装了编译时编织插件并安装了所有 AspectJ 依赖项和开发工具。

可能类似的问题： 为什么要从 AspectJ 切换到代理模式导致“TransactionRequiredException：执行更新/删除查询”不再发生？

我打算使用AspectJ而不是Spring AOP提高我的应用程序的性能。

这里我展示了三个文件的一部分。 AspectJ 开发工具包已安装。
