Spring-LDAP

下载地址 ：http://www.springframework.org/ldap



用Spring LDAP最小需要：

    * spring-ldap（spring－ldap包）
    * spring－core（用于框架内部的丰富的工具类）
    * spring－beans（方便操作java beans的接口和类）
    * spring－context（增加通过一致API为应用对象获取资源的能力）
    * spring－dao（使经常性的错误处理跟使用中的数据访问分开的异常处理机制）
    * commons－logging（简单的日志处理，内部使用）
