在自定义身份验证提供程序中使用服务层（Spring security 3.2）

Question

我不明白为什么我不能在身份验证提供者（文件：userDetailsS​​ervice）中使用服务层（文件：Userservice）。结果我有下面的错误，但是当我使用 Repository layer(file: Repository) 时一切都很好。

我想封装 Repository 层（Spring data Jpa）并仅使用 Service 层来满足所有需求。为什么在这种情况下不可能？

Answer 1

问题是spring不知道User_service bean。

User_service bean 未在您的上下文配置中声明，您也未启用组件注释类的类路径扫描。 （鉴于您发布的配置）

尝试使用以下 xml 声明打开组件扫描（可能定义一个构造型属性：

<context:component-scan base-package="your.package" />

或在上下文配置中声明您的 bean。

希望这会有所帮助！
