Micronaut JSON serialization - use getters instead of fields

When using Spring MVC, by default, whenever your @RestControllers return an object, it will be serialized into a JSON based on its getters, instead of its fields.

Is there any way I can configure Micronaut to behave like this as well? Example:

public class User {

  private String email;
  private String password;

  public String getEmail() {
    return email;
  }

}

@Controller
public class UserController {

  public User getUser() {
    ...
  }

}

So this should return:

{
  "email": "email@addres.com"
}

instead of this:

{
  "email": "email@addres.com",
  "password": "pass"
}

I'm aware of Jackson's annotations, however, I'm just trying to understand if it's possible to configure Micronaut to behave like this.

Thanks.

It should work as expected, it should not be displaying the password. No fields are displayed if there is no getter (password).

Starting with a project without any features: micronaut launch

Then

import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import io.micronaut.runtime.Micronaut;

public class Application {

    public static void main(String[] args) {
        Micronaut.run(Application.class, args);
    }
}

class User {
    String email;
    String password;

    public User(String email,String password) {
        this.email = email;
        this.password = password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getEmail() {
        return email;
    }
}

@Controller
class UserController {

    @Get
    public User getUser() {
        return new User("email@micronaut.io","secret");
    }

}

http://localhost:8080 results in:

{
"email": "email@address.com"
}
