Question

我一直收到一条消息：“org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为'userDetailsService'的bean”，即使bean被定义为UserDetailsServiceImpl类中的服务。如：

@Service(value="userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService{

我正在使用最新的Spring和Spring Security。

我不确定我做错了什么。我正在粘贴我的spring xml文件的配置。 spring-security.xml显示它在使用组件扫描时可以从servlet-context.xml中找到bean。

谢谢

Answer 1

您需要在其他Spring配置文件中放置组件扫描，而不仅仅是servlet配置。

它们是不同的上下文，一个由上下文加载器侦听器加载，一个由调度程序servlet加载。

Answer 2

确保添加

<context:annotation-config />
<context:component-scan base-package="<your package name" />

对于您的应用程序上下文，否则Spring将不知道在哪里查找使用注释声明的bean。注意，Spring将扫描您指定的包和所有子包。

Spring和Spring安全配置帮助，找不到bean
