但是, 强烈建议所有可序列化类显式声明 serialVersionUID 值,因为默认的 serialVersionUID 计算对类详细信息高度敏感,这些详细信息可能因编译器实现而异,因此在反序列化期间可能会导致意外的InvalidClassExceptions 。因此,为了保证跨不同 java 编译器实现的一致 serialVersionUID 值,可序列化类必须声明显式 serialVersion...
文件里存储的User对象的serialVersionUID跟当前的User对象(User.class)的serialVersionUID不一致。因为如果一个Java对象没有指定serialVersionUID,那么系统(JVM)动态地指定一个。 为了解决这个问题,只要在定义User对象时指定serialVersionUID就可以了,即: 1classUserimplementsSerializable {23privatestaticfinallongserialVersion...
It gives us simply more control. Default rules for generatingserialVersionUIDcan be too strict in some cases. For example when the visibility of a field changes, theserialVersionUIDchanges too. Value generated automatically can differ between various Java implementations. There is a chance that some...
采用第二种方式生成的serialVersionUID是根据类名,接口名,方法和属性等来生成的,例如: privatestaticfinallongserialVersionUID=3959055215634785113L; 当我们一个实体类中没有显式的定义一个名为“serialVersionUID”、类型为long的变量时,Java序列化机制会根据编译时的class自动生成一个serialVersionUID作为序列化版本比较...
