Spring security 使用SpringSecurity3的LDAP身份验证

Spring security 使用SpringSecurity3的LDAP身份验证,spring-security,ldap,Spring Security,Ldap,我正试图通过对组织的LDAP服务器进行身份验证来保护Spring3MVCWeb应用程序的部分安全。我是LDAP新手，所以我边走边学习。我一直在遵循文档和示例，但似乎无法正确理解这是我的security-context.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:s="http://www.sprin

它似乎不喜欢ContextSourcebean的构造函数参数中列出的URL，尽管我不知道为什么

此外，我怀疑此配置的其他部分不正确。例如，我在ldap服务器标记和ContextSourcebean中定义了ldap服务器URL。这似乎是不必要的重复，但在示例中就是这样做的。有人能仔细检查一下配置，确保它是正常的吗

此外，如果有必要，我将介绍一下LDAP服务器的布局，因为它似乎有点不标准。用户的DN由uid={the_user_name}，cn构成
