Serialization Basics and Modern Alternatives (like Record)
Explore Java serialization fundamentals, how to control serialization with serialVersionUID and transient fields, and discover modern alternatives such as records. Understand security concerns with classic serialization and learn techniques to build robust, tamper-resistant Java applications.
We'll cover the following...
Serialization allows us to convert live objects into byte streams for storage or network transmission. While it was a cornerstone of early Java development, it is now widely recognized as a severe security risk.
Let’s explore how classic serialization works, how to control it, and what modern, secure alternatives we should use instead.
What is serialization, and what should we be cautious about?
What is deserialization?
Are there any drawbacks to serialization?
What is the default form of serialization?
What is the transient keyword used for?
What is serialVersionUID?
To observe how we control serialization at the field level and define our version identifier, let’s look at a ...
