Java对象序列化底层原理源码解析

What Java序列化是指把Java对象保存为二进制字节码的过程，Java反序列化是指把二进制码重新转换成Java对象的过程。那么为什么需要序列化呢？第一种情况是：一般情况下Java对象的声明周期都比Java虚拟机的要短，实际应用中我们希望在JVM停止运行之后能够持久化指定的对象，这时候就需要...

Java序列化 ObjectInputStream源码解析

上一篇讲了类的序列化，今天要讲类的反序列化，ObjectInputStream。从内部变量中我们可以看出，内部包含一个块输入流，因为有handle机制所以也有一个内部缓存表但不是hash表 /** 处理数据块转换的过滤流 */ private final BlockDataInputStream ...

Java序列化 ObjectOutputStream源码解析

概述众所周知，Java原生的序列化方法可以分为两种：实现Serializable接口实现Externalizable接口其实还有一种，可以完全自己实现转为二进制内容，用Unsafe写到内存里面，然后写入文件 Serializable 可以使用ObjectStream默认实现的writeObj...

Java对象的序列化和反序列化源码阅读
