本文整理了Java中java.io.ObjectInputStream.readFields()方法的一些代码示例，展示了ObjectInputStream.readFields()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ObjectInputStream.readFields()方法的具体详情如下：
包路径：java.io.ObjectInputStream
类名称：ObjectInputStream
方法名：readFields

ObjectInputStream.readFields介绍

[英]Reads the persistent fields of the object that is currently being read from the source stream. The values read are stored in a GetField object that provides access to the persistent fields. This GetField object is then returned.
[中]读取当前正在从源流读取的对象的持久字段。读取的值存储在GetField对象中，该对象提供对持久字段的访问。然后返回这个GetField对象。
