最近在家调试程序时遇到序列化错误，该问题是由于实现接口的类没有指定 serialVersionUID 值导致。
以前不知道在哪看到过，如果实现了java 这个序列化接口， serialVersionUID 这个属性建议都加上，避免远程传输后反序列化时出错，这次遇到了，记录一下。
另外 serialVersionUID 必须是 final 类型的
Caused by: java.io.InvalidClassException: xx.xxx.GameQuestionVO; local class incompatible: stream classdesc serialVersionUID = 3169496111151699770, local class serialVersionUID = 1976596262898148020
