Gson serialization depending on field value
- by Serj Lotutovici
I have a POJO that is similar to:
public class MyGsonPojo {
@Expose
@SerializedName("value1")
private String valueOne;
@Expose
@SerializedName("value2")
private boolean valueTwo;
@Expose
@SerializedName("value3")
private int valueThree;
// Getters and other stuff here
}
The issue is that this object has to be serialized into a json body for a call
to the server. Some fields are optional for the request and if I even send it with default and null values, the API responds differently (Unfortunately changing the api is not an option).
So basically I need to exclude fields from serialization if any of them is set to a default value. For example if the field valueOne is null the resulting json should be:
{
"value2" : true,
"value3" : 2
}
Any idea how to make this a painless effort? I wouldn't want to build the json body manually.
Any help would be great. Thank you in advice.
