如何在java中使用未绑定的LDAP SDK从Active directory获取解码的objectGUID?
场景1:我可以从active directory获取objectGUID,但它不是可读的字符串格式。我们还需要以解码格式将其存储在数据库中。对于提供的链接“”中的给定示例,它演示了如何解码objectGUID,但他们认为objectGUID长度为16字节(128位)。在我们的例子中,当我试图获取objectGUID时,我得到的是128位以上,有时我得到的是128位以下,也就是说,我们没有得到特定的位长度。 我的实现代码供参考:如何在java中使用未绑定的LDAP SDK从Active directory获取解码的objectGUID?,java,active-directory,ldap,unboundid-ldap-sdk,Java,Active Directory,Ldap,Unboundid Ldap Sdk,场景1:我可以从active directory获取objectGUID,但它不是可读的字符串格式。我们还需要以解码格式将其存储在数据库中。对于提供的链接“”中的给定示例,它演示了如何解码objectGUID,但他们认为objectGUID长度为16字节(128位)。在我们的例子中,当我试图获取objectGUID时,我得到的是128位以上,有时我得到的是128位以下,也就是说,我们没有得到特定的位长度。 我的实现代码供参考: public class GetLDAPUsers { publi

专用静态字符串前缀零(int值){
如果(value您无法将ObjectGUID
解释为字符串。通常,我会将目录上下文环境设置为将ObjectGUID
返回为字节[]
,然后使用convert方法
env.put("java.naming.ldap.attributes.binary", "ObjectGUID");
String newGuid = convertToDashedString(guid);
春季:
注入财产
java.naming.ldap.attributes.binary
正确地输入ldapTemplate
您只需执行以下操作:
public static String getGuidFromByteArray(byte[] bytes) {
ByteBuffer bb = ByteBuffer.wrap(bytes);
long high = bb.getLong();
long low = bb.getLong();
UUID uuid = new UUID(high, low);
return uuid.toString();
}
