Getting error org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named ‘springSecurityFilterChain’ is defined

在我的 Spring 应用程序中，我不断收到此错误:

No bean named 'org.springframework.security.authenticationManager' is defined: Did you forget to add a gobal <authentication-manager> element to your configuration (with child <authentication-provider> elements)? Alternatively you can use the authentication-manager-ref attribute on your <http> and <global-method-security> elements.

在我的 Spring Security 上下文 xml 文件中，我定义了以下内容:

<beans:bean id="myUserDetailsService" class="com.myProject.core.security.MyUserDetailsService" />

<beans:bean id="encoder" class="com.myProject.core.security.HmacPasswordEncoder" />

<authentication-manager id="clientAuthenticationManager" >
    <authentication-provider user-service-ref="myUserDetailsService">
        <password-encoder ref="encoder" />
    </authentication-provider>
</authentication-manager>

当我明确定义了我的身份验证管理器和身份验证提供者后，有什么想法会提示吗？

注意:这可能会有所帮助，这是一个更具描述性的错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with 
name 'org.springframework.security.filterChains': Cannot resolve reference to bean
'org.springframework.security.web.DefaultSecurityFilterChain#2' while setting bean

最佳答案

authenticationManager 是按名称查找的，所以只需将其更改为以下内容:

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