Spring Mongo-从我的自定义存储库实现访问存储库接口方法

Question

I am defining a Spring Mongo repository interface as follows:

public interface FooRepository
  extends MongoRepository<Foo, String>, FooRepositoryCustom {
  Foo findByMyField(String myField);
}

... and a custom interface like this:

public interface FooRepositoryCustom {
  Foo findByMyObject(MyObject obj);
}

In my custom repository implementation, I would like to define findByMyObject by calling the findByMyField method. Something like:

public class FooRepositoryImpl implements FooRepositoryCustom {
  public Foo findByMyObject(MyObject obj) {
    return new Foo(<repository>.findByMyField(obj.getId()));
  }
}

Any clue of how I could get a reference to that repository interface?

Answer 1

You can try the following ...

public class FooRepositoryImpl implements FooRepositoryCustom {
@Autowired
private FooRepository fooRepository;
public Foo findByMyObject(MyObject obj) {
    return new Foo(fooRepository.findByMyField(obj.getId()));
  }
}

You can also try

@Autowired
private MongoRepository<Foo, String> fooRepository;

Not sure if the generics will trip the autowire by type.
