Salesforce Apex JSON serialization with change on variable name

Question

In Salesforce/Apex how can i serialize an Apex Class to Json/String with a change of variable names mapping ? like in java we can use @SerializedName annotation.

Answer 1

Apex does not support annotation for serialization.

But, in this type of scenario, I always follows

public class TestClass
{
    public string oldA { get; set; }
    public string oldB { get; set; }
    public string oldC { get; set; }
}

String jsonStr = JSON.serialize(objectTestClass);
jsonStr = jsonStr.replaceAll('"oldA":','"newA":');
You can use JSONGenerator to create the output yourself
