Java 自定义用户详细信息服务它似乎不是自动连接的

我花了很长时间弄清楚我的代码有什么问题。根据tomcat发送给我的跟踪信息，它与我创建的自定义

UserDetailsService

有关，该服务用于连接Spring Security和JPA，以基于数据库中的数据创建登录系统。到目前为止，我已经读了几篇关于这个问题的文章，但我还没有找到解决这个问题的方法。下面是错误跟踪：

}

顺便说一下，我使用的是SpringSecurity4.0.3和SpringMVC4.2.4，您是应用程序上下文层次结构的受害者。您的
customuserdetails服务
由
WebConfiguration
组件扫描获取并在此上下文中定义，因为：

@ComponentScan({"com.trabajotoo.saleisi.controllers", "com.trabajotoo.saleisi.dao", 
    "com.trabajotoo.saleisi.services"})
public class WebConfiguration extends WebMvcConfigurerAdapter { ... }

然后将这个bean注入
SpringSecurityConfig
，这是
WebConfiguration
的父上下文。由于
SpringSecurityConfig
无法访问在其子上下文中定义的bean，因此它将抛出
NoSuchBeanDefinitionException

为了解决这个问题，您应该在根上下文中定义
CustomUserDetailsService
。我不太熟悉您的项目结构，但通过
RootContext
或
SpringSecurityConfig
扫描服务层中的组件可能会解决您的问题。大概是这样的：

@Configuration
@ComponentScan("com.trabajotoo.saleisi.services")
public class RooContext { ... }

尝试在WebSecurityConfiguration.java中添加以下内容

@Bean
public UserDetailsService userDetailsService() {
    return super.userDetailsService();
}

有时候，文档似乎没有什么帮助，谢谢
