이 발생합니까?

Question

내 응용 프로그램을 실행할 때 예외가 발생합니다. 아무런 문제가 없기 때문에 나는 아무런 문제가 없다.하지만 나는 생산에 대해 걱정하고있다. 어떤 신체에서 그 이유를 제안 할 수 있습니까?

Answer 1

문제는 그 물체는/마샬링 할 클래스의 serialVerUID 함께 비 정렬 화

그냥 당신이있어 예외에 다음 줄을 참조하십시오 스트림 classdesc의 serialVersionUID = 0, 로컬 클래스의 serialVersionUID = 1

serialVersionUID가 일치하지 않습니다. 이것은 serialVersion UID를 변경했거나 클래스의 멤버를 변경 한 경우에 발생합니다.

당신이 같은 수업 PrinterVO에 멤버 변수를 정의 할 수 있습니다 :

고정 길이의 serialVersionUID = 0
