Java Spring安全性与EJB

我正试图在EJB应用程序中通过spring security建立一个角色用户身份验证系统。 我实现了UserDetailsService，如下所示：

@Stateless
public class UserDetailsServiceImpl implements UserDetailsService {

@Inject
private UserDAO userDao;
...
}

用户道：

@Stateless
public class UserDAOImpl implements UserDAO{

@PersistenceContext(name="persistence-unit-name")
private EntityManager em;
...
}

安全配置：

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Inject
private UserDetailsService userDetailsService;
...
}

SecurityWebApplicationInitializer：

public class SecurityWebApplicationInitializer extends 
AbstractSecurityWebApplicationInitializer {

public SecurityWebApplicationInitializer() {
    super(SecurityConfiguration.class);
  }
}

部署项目时，我有以下例外情况：

GRAVE: Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfiguration': Unsatisfied dependency expressed through field 'userDetailsService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.security.core.userdetails.UserDetailsService' available: expected at least 1 bean which qualifies as autowire candidate.

为什么不能将UserDetailsServiceImpl注入SecurityConfiguration？有什么办法解决这个问题吗？

谢谢

因为

UserDetailsServiceImpl

没有声明为Springbean

@Stateless

不适用于Spring，您需要

@Component

或其他组件。我尝试在

UserDetailsServiceImpl

中使用

@Component

并在

SecurityConfiguration

中使用

@autowired

自动连接它，但仍然得到相同的异常。有没有自动连接我的服务的想法？您确定吗？如果在使用Spring注释对其进行注释后出现相同的异常，则可能存在一些组件扫描问题。在创建应用程序上下文时，您是否扫描了Springbean的正确包？顺便说一下，您的

UserDaoImpl

也需要spring注释，因为您正在注入它的接口，因为
