RFC 6902 implementation with GSON

[Frank Seidinger]

Hi there,

I would like to know if there is any way to parse RFC 9602 compliant JSON patch documents and apply the patch to either another JSON document or a deserialized object using GSON.

In pseudo code this would look something like:

GsonBuilder gsonPatchBuilder = new GsonBuilder();

Gson gsonPatchParser = gsonPatchBuilder.create();

JsonPatch patch = gsonPatchParser.fromJson(jsonPatchString);

GsonBuilder gsonBuilder = new GsonBuilder();

gsonBuilder.applyPatch(patch);

Gson gsonParser = gsonBuilder.create();

MyObject myObject = gsonParser.fromJson(jsonString);

Resulting in a MyObject class patched by the RFC 9602 patch document.

I've seen so far only solutions for Jackson but non for GSON.

Kind regards,

Frank.

Gson currently lacks support for RFC 6901 (patch) and RFC 6902. Building these on top of Gson's tree API should be straightforward.

You can use a third party library to create/apply JSON patches:
