Spring引导 - 无法代理接口实现方法 - WARN消息

Question

人。 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MethodSecurity和@Secured注释在Controller类中可以引起这种警告，但似乎我从另一个地方获取它们。 如何知道从哪里收到这些警告？

Answer 1

问题在于Class级别的一些@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

根据报告的问题，我遇到了类似于使用最终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。

Answer 3

在检查 @Transactional 注释后，确保您将 @Repository 注释直接放入存储库界面。就我而言，我执行了以下操作：

1. 从我的 DAO 类
中删除了 @Transactional 和 @Repository
2. 将 @Repository 放入我的 repo 界面
3. 将 @Component 放入我的 DAO 类
