目前只實現(xiàn)了java生成的固定的uuid：85bb94b8-fd4b-4e1c-8f49-3cedd49d8f28的序列化

java讀取測試

public class Test { public static void main(String[] args) throws IOException, ClassNotFoundException { readUUIDTest(); } private static void readUUIDTest() throws IOException, ClassNotFoundException { try (var fis = new FileInputStream('uuid-go.out'); var is = new ObjectInputStream(fis)) { var uuid = is.readObject(); System.out.print(uuid); } }}

到此這篇關(guān)于golang實現(xiàn)java uuid的序列化方法的文章就介紹到這了,更多相關(guān)golang實現(xiàn)java uuid序列化內(nèi)容請搜索好吧啦網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持好吧啦網(wǎng)！
