伙计们。从 Spring boot 1.5.x 开始，我收到以下 WARN 消息：

我在依赖层次结构中没有 CGLIB。我只使用 DI 接口，并且我尝试禁用 @EnableGlobalMethodSecurity(securedEnabled = true) 以及与之相关的所有内容，但仍然没有更改。（我已经阅读了控制器类中的 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。如何知道我从哪里收到这些警告？

【解决方案1】：

问题在于类级别的一些@Transactional 注释。在我将它们放在接口上之后（存储库 - 我正在使用 spring 数据）一切都很好:)

【解决方案2】：

检查@Transactional注解后，确保你将@Repository注解直接放到repository interface。就我而言，我做了以下事情：

从我的 DAO 类中删除了 @Transactional 和 @Repository
把@Repository放到我的repo界面
将@Component 放入我的DAO 课程

【解决方案3】：

根据报告的问题，我遇到了同样的问题，例如使用 final 实现接口的方法。

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。
