公司有个子服务较多,交互频繁的系统,有一些需要共享传输的对象,它们通过Java Object Serialization后进行交互;但是由于一些不可描述的历史原因,这些对象存在多个版本,每个版本中的属性不一致,且未设置serialVersionUID。这阵子在做梳理/统一代码的工作,打算统一这些对象的版本和固定serialVersionUID,但是由于服务较多,上线发...
重点介绍下java序列化. JDK1.1起,sun就有Java Object Serialization Specification定义java的序列化方式,根据文档,可以根据字节流读出序列化后的含义. 地址在这里. 借用一张java rmi的图解释一下其工作方式: 客户端与服务端都需要有实现了rmi接口的实现类,该接口在实际远程通信的时候作为一个桩类来处理网络通信的各种...
本文介绍了如何在Java中序列化指定的字段。通过使用transient关键字或自定义writeObject和readObject方法,我们可以灵活地控制对象的序列化和反序列化过程。 希望本文对你理解Java序列化指定字段有所帮助。如果有任何疑问,请随时在下方留言。谢谢阅读! 参考文献 [Java Object Serialization Specification](...
“Java对象序列化规范” Java Object Serialization Specification,网址为: http://docs.oracle.com/javase/7/docs/platform/serialization/spec/serialTOC.html 2、为什么叫序列化 个人猜测: 由于保存对象的过程,是把对象保存为一连串字节流,而英文Serialization的意思“序列化”,所以序列化形象的表述了这个过程。
