自定义 Spring 3.0 安全过滤器、多个入口点、AuthenticationProvider

我需要我的安全性具有以下逻辑：

1. 检查标头参数是否存在
2. 根据参数的存在，重定向到登录页面（如果未经过身份验证），或检查基本身份验证令牌

在这两种情况下，我都有相同的身份验证提供程序，但我无法让它工作。 委托入口点工作正常，但我从未进入我的自定义身份验证提供程序......

这是我的安全配置：

    <security:global-method-security
    secured-annotations="enabled" />

<security:http entry-point-ref="delegatingAuthenticationEntryPoint"
    use-expressions="true" auto-config="false">
    <!-- <security:custom-filter position="FORM_LOGIN_FILTER" -->
    <!-- ref="usernamePasswordAuthenticationFilter" /> -->
    <!-- <security:custom-filter position="BASIC_AUTH_FILTER" -->
    <!-- ref="basicAuthenticationFilter" /> -->
    <security:intercept-url pattern="/login*"
        filters="none" />
    <security:intercept-url pattern="/portimaLogin*"
        filters="none" />
    <security:intercept-url pattern="/**"
        access="isAuthenticated()" />
</security:http>

<bean id="delegatingAuthenticationEntryPoint"
    class="org.springframework.security.web.authentication.DelegatingAuthenticationEntryPoint">
    <constructor-arg>
        <map>
            <entry key="hasHeader('portima','true')" value-ref="PortimaLoginUrlAuthenticationEntryPoint" />
        </map>
    </constructor-arg>
    <property name="defaultEntryPoint" ref="authenticationEntryPoint" />
</bean>

<bean id="usernamePasswordAuthenticationFilter"
    class="org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="authenticationFailureHandler" ref="authenticationFailureHandler" />
</bean>

<bean id="basicAuthenticationFilter"
    class="org.springframework.security.web.authentication.www.BasicAuthenticationFilter">
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="authenticationEntryPoint" ref="authenticationEntryPoint" />
</bean>

<bean id="PortimaLoginUrlAuthenticationEntryPoint"
    class="be.ap.common.security.spring.PortimaLoginUrlAuthenticationEntryPoint">
    <property name="loginFormUrl" value="${portima.login.page}" />
</bean>

<bean id="authenticationEntryPoint"
    class="org.springframework.security.web.authentication.www.BasicAuthenticationEntryPoint">
    <property name="realmName" value="AP" />
</bean>

<security:authentication-manager alias="authenticationManager">
    <security:authentication-provider
        ref="authenticationProvider" />
</security:authentication-manager>

<bean id="authenticationProvider" class="be.ap.common.security.spring.APAuthenticationProvider" />

<bean id="userDetailsService" class="be.ap.common.security.spring.APUserDetailsService" />

任何想法 ？

我终于可以工作了。

这是我的上下文文件：

    <security:http entry-point-ref="delegatingAuthenticationEntryPoint"
    use-expressions="true">
    <security:custom-filter position="PRE_AUTH_FILTER"
        ref="preAuthenticationFilter" />
    <security:custom-filter position="FORM_LOGIN_FILTER"
        ref="usernamePasswordAuthenticationFilter" />
    <security:custom-filter position="BASIC_AUTH_FILTER"
        ref="basicAuthenticationFilter" />
    <security:intercept-url pattern="/login*"
        filters="none" />
    <security:intercept-url pattern="/portimaLogin*"
        filters="none" />
    <security:intercept-url pattern="/accessDenied*"
        filters="none" />
    <security:intercept-url pattern="/**"
        access="isAuthenticated()" />
    <security:access-denied-handler ref="accessDeniedHandler" />
</security:http>

<!-- Spring Security Authentication Manager -->

<bean id="userDetailsService" class="be.ap.common.security.spring.APUserDetailsService" />

<!-- for Mock -->
<bean id="SSOService" class="be.ap.security.service.SSOServiceMockImpl" />

正如你所看到的，我也添加了一些东西。

为了解决这个问题，我删除了自动配置属性，取消注释过滤器，并正确定义它们。

对于其他想要快速了解其用途的人，以下是流程：

1. PRE_AUTH_FILTER 将检查类似 SSO 的服务来预填充身份验证对象（如果已在 SSO 中进行身份验证）
2. 然后 delegatingAuthenticationEntryPoint 将根据请求标头选择如何进行身份验证
3. The two ways are :
   • 自定义 LoginUrlAuthenticationEntryPoint
   • 自定义BasicAuthenticationEntryPoint

当 PreAuth 使用我的 SSO 服务时，BasicAuth 和 LoginURLAuth 使用相同的 AuthenticationProvider。

希望它对其他人有帮助！
