说到春天，我是相当绿色的。

尝试自动将以下连接在一起时收到此消息，但我还没有解决它。

org.springframework.beans.factory.BeanCreationException: Error creating bean wit h name 'authenticator': Injection of autowired dependencies failed; nested excep tion is org.springframework.beans.factory.BeanCreationException: Could not autow ire method: public void nz.co.myproject.auth.Authenticator.setAuthenticationManag er(org.springframework.security.authentication.AuthenticationManager); nested ex ception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No m atching bean of type [org.springframework.security.authentication.Authentication Manager] found for dependency: expected at least 1 bean which qualifies as autow ire candidate for this dependency. Dependency annotations: {}

弹簧配置

<authentication-manager alias="authenticationManager">
  <authentication-provider user-service-ref="myUserDetailsService">
    <password-encoder ref="encoder"/>
  </authentication-provider>
</authentication-manager>

<beans:bean id="myUserDetailsService" class="nz.co.myproject.auth.MyUserDetailsService" />

<beans:bean id="authenticator" class="nz.co.myproject.auth.Authenticator"/>

<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>

我的课

@Component
public class Authenticator {

        /* Authentication manager does not inject successfully, instead gives error message */
        @Autowired
    @Qualifier("authenticationManager")
    protected AuthenticationManager authenticationManager;

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

    public void setAuthenticationManager(AuthenticationManager authenticationManager) { 
        this.authenticationManager = authenticationManager;
    }
}

有什么作用

有趣的是，我只有在尝试将身份验证管理器注入 Authenticator 时才得到这个。当我尝试将身份验证管理器注入 HomeController 时，依赖项注入成功。

例如，以下工作：

弹簧配置

<authentication-manager alias="authenticationManager">
        <authentication-provider user-service-ref="myUserDetailsService">
            <password-encoder ref="encoder"/>
        </authentication-provider>
    </authentication-manager>

    <beans:bean id="myUserDetailsService" class="nz.co.myproject.auth.MyUserDetailsService" />

    <beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>

我的课

@Controller
public class HomeController {

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

    /* authentication manager injects successfully */
    @Autowired
    @Qualifier("authenticationManager")
    protected AuthenticationManager authenticationManager; 

       ......

}

谁能看到我错过了什么？

authenticationManager在您的 bean 定义 XML 中没有命名bean。第二个 bean 定义示例按照您的id="authenticationManager"方式工作。所以你用 id:authenticationManager 创建了 bean

我认为多个component scan标签不起作用。

改变：

<context:component-scan base-package="nz.co.myproject.controller" /> <context:component-scan base-package="nz.co.myproject.auth" />

至：

<context:component-scan base-package="nz.co.myproject" />

这将在 的所有子包中查找所有 , 等注释@Component，并启用它们进行自动装配。@Controllernz.co.myproject
