在Java 中,transient 是一个关键字,用于指定一个类的字段(成员变量)在序列化时应该被忽略。在 Java 对象序列化期间,对象的状态被转换为字节流,以便在网络上传输或持久保存到磁盘。如果一个字段被标记为 transient,那么它的值不会被序列化,在反序列化时会被恢复其默认值。 简单示例 public class Example implements...

JAVA的50个常用关键字里有些必须掌握且用处很多,今天我们来了解下static、final、transient这三个关键字。 一、static关键字 static是静态的意思,经其修饰不用再创建可以直接调用,其作用有修饰变量、修饰方法,…

Java 中的 transient 关键字被用来表示变量将不被序列化处理。那么在理解 transient 关键字之前,我们先了解下什么是序列化。 什么是序列化 序列化是对象进行持久化处理,也就是说,将对象转化成一个字节流进行存储(比如存储为一个字节文件)或传输(通过网络传输字节)。
