原始问题概要: 使用带有 AOP 代理的标准 Spring 事务，不可能从同一类中的非 @Transactional-marked 方法调用 @Transactional-marked 方法并在事务中(特别是由于上述代理)。这在 AspectJ 模式下使用 Spring Transactions 应该是可能的，但它是如何完成的？

编辑: 使用 加载时间 编织的 AspectJ 模式下 Spring 事务的完整纲要:

将以下内容添加到 META-INF/spring/applicationContext.xml :

通过阅读您的问题，您并不清楚您的问题在哪里，因此我将简要列出让 AspectJ 拦截您的 @Transactional 所需的条件。方法。
