引导至Java中的Base64

结构略有不同，但是在字节数组的第一部分交换一些字节可以解决您的问题。

java.util.base64.Enprer enprer= base64.getEnprer();UUID uuid = UUID.fromString("be9f1bb6-5c8e-407d-85a3-d5ef31f21b4d");ByteBuffer bb = ByteBuffer.wrap(new byte[16]);bb.putLong(uuid.getMostSignificantBits());bb.putLong(uuid.getLeastSignificantBits());byte[] uuid_bytes = bb.array();byte[] guid_bytes = Arrays.copyOf(uuid_bytes,uuid_bytes.length);guid_bytes[0] = uuid_bytes[3];guid_bytes[1] = uuid_bytes[2];guid_bytes[2] = uuid_bytes[1];guid_bytes[3] = uuid_bytes[0];guid_bytes[4] = uuid_bytes[5];guid_bytes[5] = uuid_bytes[4];guid_bytes[6] = uuid_bytes[7];guid_bytes[7] = uuid_bytes[6];String result = enprer.enpreToString(guid_bytes);
