创建名称为 AuthenticationManager 的 bean 时出错

Question

我正在开发一个使用 Spring-Security 的 Spring-MVC 应用程序。在登录申请中我必须使用 2 登录 url 的

/j_spring_security_check_for_person 和
/j_spring_security_check_for_group

登录名 url 都会检查我在其中实施了 UserDetails 和 userDetailsService 的数据库。要连接这两个 url 以进行登录，我正在使用 springSecurityFilterChain。不幸的是，它不起作用。我从 2 天开始就遇到这个问题，我可能犯了一些愚蠢的错误。请检查日志和xml,

错误日志：

如果我用下面的代码片段替换身份验证管理器代码，我不会收到错误，但是 2 个登录 url 没有注册：

<security:authentication-manager alias="authenticationManager">
            <security:authentication-provider user-service-ref="userDetailsService">
                <security:password-encoder ref="encoder"/>
            </security:authentication-provider>
            <security:authentication-provider user-service-ref="groupDetailsService">
                <security:password-encoder ref="encoder"/>
            </security:authentication-provider>
        </security:authentication-manager>-->

Answer 1

如异常消息所示，您的 authenticationManagerForGroup 和 authenticationManagerForPersonal 配置无效。从类型签名和 JavaDoc 中可以发现，ProviderManager 将 AuthenticationManager 的列表作为构造函数参数，但是您将 AuthenticationManager 配置为属性个参数。

您应该可以通过将 <property name="providers"> 元素替换为 <constructor-arg> 来实现此功能。

Answer 2

authenticationManagerForPersonal 和 authenticationManagerForGroup 是 bean 类型 ProviderManager。这是错误的。您必须将这些 bean 声明为 DaoAuthenticationProvider 类型。请仔细看看我的配置。
