Spring引导 - 无法代理接口实现方法 - WARN消息

Question

家伙。从Spring boot 1.5.x开始，我收到以下WARN消息：

     :: Spring Boot ::        (v2.0.0.RELEASE)

我没有依赖层次结构中的CGLIB。我只使用DI接口，我试图禁用@EnableGlobalMethodSecurity（securedEnabled = true）以及与之相关的所有内容，但仍然没有变化。（我已经读过Controller类中的MethodSecurity和@Secured注释可能导致这个警告，但似乎我从另一个地方得到它们。如何知道从哪里收到这些警告？

Answer 1

问题出在类级别上的一些@Transactional注释。我把它们放在接口上（存储库 - 我使用弹簧数据）一切都OK :)

Answer 2

基于报告的问题，我遇到了类似于具有final的接口实现方法的问题。

从具体类（Bean）中，如果我们从方法中删除final，也解决了同样的问题。
