问题 I have domain: class Company { List<Job> jobs; } Is there a way to return nested object from collection like: @Repository public interface CompanyRepository extends MongoRepository<Company, String>{ Job findByJobId(String jobId); } 回答1: I have to make some assumptions about the structure of your Job model, but assuming something like this: public class Job { private String id; // other attributes and methods } ... and assuming that this model is embedded in your Company model, and not

问题 Is it possible to use named parameters for a @Query method in a mongodb repository, just like we can do with a jpa repository (http://docs.spring.io/spring-data/jpa/docs/1.4.3.RELEASE/reference/html/jpa.repositories.html section 2.3.5)? As an example, I would like to use the following code: @Query("{'store' : :store, 'app' : :app }") List<T> findByStoreAndApp(@Param("store") String store, @Param("app") String app); instead of: @Query("{'store' : ?0, 'app' : ?1 }") List<T> findByStoreAndApp
