How to use a specific Json Serialize in JAX-RS?

Question

I'm using the Gson Library and JAX-rs for a RestFull-API project. This is my endpoint:

@POST
@PermitAll
@Path("/search")
public List<Model> listAll(@BeanParam @Valid PageRequest page, SearchModelRequest request) {
    List<Model> models = modelDao.getOrderedByViews(page);
    return models;
}

The system automatically serialise the model object with a full JSON with all attributes, but I just want to send some of them; how Can I do?

Does this answer your question? [Gson: How to exclude specific fields from Serialization without annotations](https://stackoverflow.com/questions/4802887/gson-how-to-exclude-specific-fields-from-serialization-without-annotations) — Jasper de Vries, Jul 02 '20 at 14:02
If you are using a Java EE container, I'd suggest to switch to JSON-B. — Jasper de Vries, Jul 02 '20 at 14:34

By default in Gson if you mark the field as transient, it won't be considered in parsing.

e.g.:

private transient String name = "";

Nevertheless there are more ways to do it as explained in documentation:
