When instantiating (constructing) the actual object(the thing) from a class (blueprint) there is a need to save the object (thing) by serializing it (breaking it down to its basic atomic structure) to a space in memory. (Kind of like Star Treks Transporter). You break the thing down into it stream of information that can be transported somewhere and stored. Then when you want to reconstruct the thing you just pull the atomically stored instance back into the object. Different from instaniation.

序列化是将Java、c#或任何其他(OOP语言)支持的对象转换为可移植形式的过程。通过这种方式，它可以通过网络传输或存储在磁盘上。对于可序列化的类，它必须实现可序列化的接口。

什么是序列化?

图片类比解释:

简介:

序列化意味着将某物(例如我的狗Rex)转换成一系列的1和0 -可以运输/存储等。我的海外朋友可以把这些1和0翻译成小狗的完美表现(反序列化)。

类比澄清

朋友们，这是个类比。我认为你还不能连载一只小狗。您可以序列化数据结构或其他复杂对象。(我写这个答案是为了让您能够以一种有趣的方式，在不到3秒的时间内理解这个概念，而不用绞尽脑汁去理解一个核心的技术定义)，但如果您更喜欢一个规范的定义，请查看维基百科关于序列化的条目。

序列化是指当对象的状态可以保存在文件中时，对象(内存块)转换为一种形式(例如)。

就像做饼干一样，对象是一个面团，饼干是一个序列化的面团。

所以通过“序列化”，你可以把cookie发送给你的朋友。

就像这样:-)

Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization. ... This illustration shows the overall process of serialization ... Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications

(强调我的)

序列化是将对象转换为可存储的位序列。

所以你可以保存这个序列到一个文件，db或通过网络发送。

稍后，您可以将其反序列化为实际对象，并在需要时重用它。

Web服务和AJAX是序列化最常见的例子。对象在向客户端发送响应之前被序列化。
