java 自定义 UserDetailsS​​ervice 似乎不是自动装配的

Custom UserDetailsService it seems to be not autowired

提问by DevKev

Well I've expended quite a time figuring out what the problem with my code is. According to the trace that tomcat is sending me it has something to do with a custom UserDetailsServicethat I create for connecting Spring Security and JPA to make a login system based on data in a Database. I've read several articles so far talking about this issue but I haven't found a solution for my one. So heres the error trace:

好吧，我花了很长时间才弄清楚我的代码有什么问题。根据 tomcat 发送给我的跟踪，它与UserDetailsService我为连接 Spring Security 和 JPA 以基于数据库中的数据创建登录系统而创建的自定义有关。到目前为止，我已经阅读了几篇讨论这个问题的文章，但我还没有找到适合我的解决方案。所以继承人的错误跟踪：

    UsernameNotFoundException {
        Usuario user = userService.findByUsername(userName);
        if (user == null){
            System.out.println("User not found");
            throw new UsernameNotFoundException("Username not found");
        }

        return new User(user.getNomUsuario(), user.getPassword(), user.isEstado(),
                true, true, true, getGrantedAuthorities(user));
    }

    private List<GrantedAuthority> getGrantedAuthorities(Usuario user){

            rolAsign.getRol().getCodigo()));
                break;

AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {

    }

    @Override

    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

}

By the way I'm using Spring Security 4.0.3 and Spring MVC 4.2.4

顺便说一下，我使用的是 Spring Security 4.0.3 和 Spring MVC 4.2.4

Try adding below in WebSecurityConfiguration.java

尝试在 WebSecurityConfiguration.java 中添加以下内容

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

You're the victim of Application Context Hierarchies. Your CustomUserDetailsServiceis picked up by WebConfigurationcomponent scanning and defined in this context, since:

您是Application Context Hierarchies的受害者。您CustomUserDetailsService被WebConfiguration组件扫描选中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 { ... }

Then you're gonna inject this bean into SpringSecurityConfig, which is WebConfiguration's parent context. Since SpringSecurityConfigcan not access to the beans defined in its child context, it will throw a NoSuchBeanDefinitionException.

然后你要把这个 bean 注入SpringSecurityConfig，它是WebConfiguration的父上下文。由于SpringSecurityConfig无法访问在其子上下文中定义的 bean，它将抛出一个NoSuchBeanDefinitionException.

In order to solve this problem, you should define CustomUserDetailsServicein root context. I'm not quite familiar with your project structure but scanning components in the service layer by RootContextor SpringSecurityConfigmay fix your problem. Something like this:

为了解决这个问题，你应该CustomUserDetailsService在根上下文中定义。我不太熟悉您的项目结构，但扫描服务层中的组件RootContext或SpringSecurityConfig可能会解决您的问题。像这样的东西：

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