Java-Spring: Как выдавать JSON со связями?

Всем доброго дня!
Сервер написан на Java + Spring framework + Postgresql. Мне нужно выдавать JSON такого вида:

Категория1:
    id
    name
     Подкатегория1
        id
        name
         Товар1
           id
           name
Категория2:
    id
    name
     Подкатегория1
        id
        name
         Товар1
           id
           name

Но сейчас у меня реализовано так:

Товар1
   id
   name

Мой код:
Controller:

@RestController
public class ReminderController {
    @Autowired
    private BasicService service;
    @RequestMapping(value = "/dishes", method = RequestMethod.GET)
    @ResponseBody
    public List<Dish> getAllDishes() {
        return service.getAllDishes();
    }
    @RequestMapping(value = "/categories", method = RequestMethod.GET)
    @ResponseBody
    public List<Categories> getAllCategories() {
        return service.getAllCategories();
    }
    @RequestMapping(value = "/menu", method = RequestMethod.GET)
    @ResponseBody
    public List<Menu> getAllMenu() {
        return service.getAllMenu();
    }
    @RequestMapping(value = "/reminders/{id}", method = RequestMethod.GET)
    @ResponseBody
    public Dish getReminder(@PathVariable("id") long remindId) {
        return service.getById(remindId);
    }
    @RequestMapping(value = "/reminders", method = RequestMethod.POST)
    @ResponseBody
    public Dish saveReminder(@RequestBody Dish dish) {
        return service.save(dish);
    }
    @RequestMapping (value = "/reminders{id}", method = RequestMethod.DELETE)
    @ResponseBody
    public void delete(@PathVariable long id) {
        service.remove(id);
    }
}

Сущности: Categories.java
