【问题描述】：

我正在尝试结合 Java-config 和 xml-config 进行 Spring 安全认证。但我收到一个错误：

我的代码似乎有什么问题？一直在谷歌搜索答案，但没有找到任何答案。

提前致谢。希望你能帮助我。

我已经在我的 servlet-context.xml 中声明了组件扫描

<context:component-scan base-package="ph.project.p3.conf" />

【问题讨论】：

你是如何解决这个问题的？

【参考方案1】：

您可以尝试添加@Component 注释。这样自动装配应该可以工作。

【参考方案2】：

您需要在 Spring-config 文件中添加<context:component-scan>。否则，您的应用程序将不会扫描您的包结构以在应用程序上下文中查找和注册 bean。

语法： <context:component-scan base-package="org.example.<yourapplicationName>"/> 例如：<context:component-scan base-package="oph.project.p3.conf"/>

嗨@AnilSatija，感谢您的回复。正如我在上面的问题中所说，我已经在我的 servlet-context.xml 上声明了组件扫描，并在我的 root-context.xml 上也尝试了它。我也试过“ph.project.p3”删除.conf，但仍然发生同样的错误，无法自动连接AuthorizationConfiguration。
