一、JAVA使用UUID自动生成ID
public static String getUUID(){
UUID uuid=UUID.randomUUID();
String str = uuid.toString();
String uuidStr=str.replace("-", "");
return uuidStr;
}
二、js使用UUID自动生成ID
function guid() {return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
var r = Math.random() * 16 | 0,
v = c == 'x' ? r : (r & 0x3 | 0x8);
return v.toString(16);
});
}
