Java中的实体类为什么要 implements Serializable?

1.序列化和反序列化首先来解释一下什么是序列化和反序列化:序列化:把对象转换为字节序列的过程称为对象的序列化。反序列化:把字节序列恢复为对象的过程称为对象的反序列化。在Java和其他语言进行通信的时候,需要将对象转化成一种通用的格式例如Json(转换成大家都认识的对象),从对象到Json字符串的转换过程就是序列化的过程,反过来,从Json字符串转换成Java对象的过程就是反序列化的过程。当Java需要把一个对象的状态保存到文件或者是数据库的时候,就是数据存取的过程中的中间过程,就需要序列化。我们可以把序列化的过程理解为"freeze",它将一个Java对象freeze,然后进行存储;等到再次需
