序列化 serialization

2018-07-03 15:47 更新

Serialization is a mechanism by which you can save the state of an object by converting it to a byte stream.

JAVA中實(shí)現(xiàn)serialization主要靠?jī)蓚€(gè)類(lèi):

  • ObjectOuputStream
  • ObjectInputStream

他們是JAVA IO系統(tǒng)里的OutputStream和InputStream的子類(lèi)

自定義序列化的作用如下：

  1. Persist only meaningful data.
  2. Manage serialization between different versions of your class.
  3. Avoid exposing the serialization mechanism to client API.
