如何通过Spring中CrudRepository的`findAll（）方法在序列化中包含已恢复对象的id？

Question

I have the following entity class:

@Entity
public class GameSet {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String question;
    .......
}

Here is my Repository:

@Repository
public interface GameSetRepository extends CrudRepository<GameSet, Long> { }

Here is the relevant part of my Controller:

...
    @RequestMapping(value = "/test/getgamesets", method = RequestMethod.GET)
    public @ResponseBody Collection<GameSet> getGameSets() {
        return Lists.newArrayList(gamesets.findAll());
    }
...

And here is the server response:

{
    "question": "Choose one of the following, which is wrong.",
    "title1": "MovieA",
    "title2": "MovieB",
    "title3": "MovieC",
    "title4": "MovieD",
    "wrong": 1,
    "explain": "I don't know why this is wrong.",
    "rates": 0,
    "rate": 0
}

I would like to get the id of the object in the request result, in addition to the other properties.

Should I override the findAll() method?

Thanks for the attention and time!

Answer 1

I just add the following code on my Application class from the previous link:

@Configuration
public static class RepositoryConfig extends RepositoryRestMvcConfiguration {
    @Override
    protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
        config.exposeIdsFor(GameSet.class);
    }
}

And it works!!! Thanks JB Nizet to make me see clear what was my problem!
