java通过ldap获取安全组属性乱码问题_java.naming.ldap.attributes.binary

安全组属性objectSid、objectGUID直接转为string会出现乱码，需要将其先转为byte再转为string
具体实现

1. 连接ldap添加环境

env.put("java.naming.ldap.attributes.binary", "objectSid objectGUID");

2. 转换属性

byte[] sidBytes = (byte[]) attributes.get("objectSid").get();
String objectSid = bytesToHexString(sidBytes));

3. bytesToHexString实现

public static String bytesToHexString(byte[] bytes) {
    StringBuilder hexString = new StringBuilder();
    for (byte b : bytes) {
        String hex = Integer.toHexString(0xFF & b);

        if (hex.length() == 1) {
            hexString.append('0');
        }

        hexString.append(hex);
    }
    return hexString.toString();
}
