I am trying to combine Java-config and xml-config for spring security authentication. But i received an error:

我正在尝试结合 Java-config 和 xml-config 进行 spring 安全身份验证。但我收到一个错误：

i have already declared component-scanning in my servlet-context.xml

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" />

You need to add <context:component-scan>in Spring-config file. Otherwise your application will not scan your package structure to find and register beans within application context.

您需要添加<context:component-scan>Spring-config 文件。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。

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

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

You could try adding a @Componentannotation. That way the autowiring should work.

您可以尝试添加@Component注释。这样自动装配应该可以工作。
