我是春天的新手。我最近学会了使用 Spring 3.1 来实现 LDAP 身份验证。我被告知要自定义身份验证,以便如果来自数据库中 IP 地址的用户访问该站点,他/她将自动登录(不是我的想法,我被命令这样做)。如果没有,该人将被发送到登录屏幕以进行 LDAP 身份验证

我制作了一个自定义 PreAuthenticationFilter 的骨架来检查这些用户,确定他们是否来自指定的 IP 地址之一,然后将它们发送到身份验证过程的其余部分。

我是 Spring 的新手。所以我从例子中拼凑起来,并多次阅读参考资料。

当我尝试运行它时,我收到一条错误消息,在我看来我没有正确设置我的标签或者我留下了一大块(我需要第二个自定义的 AuthenticationEntry 点吗?)

任何克服此错误的提示将不胜感激:

我相信您的安全配置的某些部分与您在s:http配置中多个地方的使用方式不一致。我建议尝试以下配置:

<s:http auto-config="true" use-expressions="true">

    <s:intercept-url pattern="/login*" access="isAnonymous()" />
    <s:intercept-url pattern="/search*" access="isAnonymous()" />
    <s:intercept-url pattern="/css/**" access="isAnonymous()" />
    <s:intercept-url pattern="/js/**" access="isAnonymous()" />
    <s:intercept-url pattern="/images/**" access="isAnonymous()" />
    <s:intercept-url pattern="/**" access="isAuthenticated()" />

    <s:form-login login-page="/login"
      authentication-failure-url="/loginfailed" />
    <s:logout logout-success-url="/logout" />

</s:http>

无论是否点击,您都需要激活身份验证过程/login;所以我建议使用预认证过滤器 AbstractPreAuthenticatedProcessingFilter的实现。您的过滤器将使用 IP 地址进行身份验证并填充Authentication对象,因此不再重定向到登录页面。过滤器应配置在 位置PRE_AUTH_FILTER您可以在Spring Source blog找到类似的 GAE 用例实现。

在您的实现中,您需要消除属性authenticationManager,它由父类管理。
