使用Spring Data Repository向mongo JSON @Query添加排序

import org.springframework.data.domain.Sort;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.mongodb.repository.Query;
import org.springframework.stereotype.Repository;

@Repository
public interface MyEntityRepository extends MongoRepository<MyEntity, String> {

    @Query("{ 'fieldName': ?0 }")
    List<MyEntity> findByFieldName(String fieldName, Sort sort);
}

import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Service;

@Service
public class MyEntityService {

    private final MyEntityRepository repository;

    public MyEntityService(MyEntityRepository repository) {
        this.repository = repository;
    }

    public List<MyEntity> findByFieldName(String fieldName, Sort sort) {
        return repository.findByFieldName(fieldName, sort);
    }
}

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyEntityController {

    private final MyEntityService service;

    public MyEntityController(MyEntityService service) {
        this.service = service;
    }

    @GetMapping("/findByFieldName")
    public List<MyEntity> findByFieldName(@RequestParam("fieldName") String fieldName,
                                           @RequestParam(value = "sortBy", defaultValue = "asc") String sortBy) {
        Sort sort = Sort.by(sortBy);
        return service.findByFieldName(fieldName, sort);
    }
}
