Currently I am working on serializing a Java object to JSON using Gson. My goal is to exclude a specific field in one class while keeping it in another.
Here's a snippet of the code:
Class A {
var a;
var b;
}
Class B {
var a;
var c;
}
Class C {
class A;
class B;
}
I need to skip a only in A, without affecting B. However, I cannot use annotations on the fields and manually removing a from object A is not an option. I am seeking a generic approach to achieve this.
A similar question was asked on Stack Overflow: Gson: How to exclude specific fields from Serialization without annotations. The solution proposed by Nishant aligns with my thinking, but there was an error in the condition provided.
f.getDeclaringClass() == c
The GetDeclaringClass method returns the type of the class, not the parent class.
I have implemented custom exclusion strategies using Gson where I can utilize methods like shouldSkipClass(class) and shouldSkipField(fieldAttributes). However, I am looking for a way to combine these strategies to skip a field only if it belongs to a specific class.
shouldSkipFieldUnderClass(class, fieldAttributes)
Are there any other approaches to achieve this? Have I overlooked something in my implementation? Any suggestions on how to skip fields in a specific class using Gson would be appreciated.
