Пользовательский запрос Spring Data JPA + REST

2015-01-27 6 views

В моей базе данных у меня есть таблица «CITA» с такими атрибутами: id, fecha_hora, descripcion, id_empleado, id_cliente.Пользовательский запрос Spring Data JPA + REST

Too, у меня есть Spring JPA Repository:

public interface CitaRepository extends JpaRepository<Cita, Long> {...}

И мне нужен этот запрос:

"SELECT id_empleado, count(id) from Cita GROUP BY id_empleado ORDER BY fecha_hora"

Моя проблема заключается в том, что я не знаю, где я должен поставить это вернуть мне что-то вроде Карта

Потому что она не работает:

@Query("SELECT id_empleado, count(id) from Cita GROUP BY id_empleado ORDER BY fecha_hora") 
    Map<Integer,Integer> estadisticas();

EDIT

У меня есть ошибки, если я пытаюсь вызвать Estadisticas() от моего контроллера REST.

Это мой контроллер REST:

@RestController 
@RequestMapping("/app") 
public class CitaResource { 

    private final Logger log = LoggerFactory.getLogger(CitaResource.class); 

    @Inject 
    private CitaRepository citaRepository; 

@RequestMapping(value = "/rest/citas/estadisticas", 
     method = RequestMethod.GET, 
     produces = MediaType.APPLICATION_JSON_VALUE) 
@Timed 
public List<CitaDTO> estadisticas() { 
    return citaRepository.estadisticas(); 
}

Это мой JPA хранилище:

public interface CitaRepository extends JpaRepository<Cita, Long> { 

@Query("SELECT new com.raquel.tfg.web.rest.dto.CitaDTO(c.empleado_id, count(c)) from Cita c GROUP BY c.empleado_id ORDER BY c.fecha_hora") 
    List<CitaDTO> estadisticas(); 

}

Это мой DTO класс:

package com.raquel.tfg.web.rest.dto; 

public class CitaDTO { 

    private int empleado_id; 
    private long count; 

    public CitaDTO(int empleado_id, long count) { 
     this.empleado_id = empleado_id; 
     this.count = count; 
    } 
    //get & set 
}

Это мой сущность Читинская:

@Entity 
@Table(name = "T_CITA") 
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) 
public class Cita implements Serializable { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private Long id; 

    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime") 
    @JsonSerialize(using = CustomDateTimeSerializer.class) 
    @JsonDeserialize(using = CustomDateTimeDeserializer.class) 
    @Column(name = "fecha_hora", nullable = false) 
    private DateTime fecha_hora; 

    @Column(name = "descripcion") 
    private String descripcion; 

    @ManyToMany 
    @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) 
    private Set<Servicio> servicios = new HashSet<>(); 

    @ManyToOne 
    private Cliente cliente; 

    @ManyToOne 
    private Empleado empleado; 
}

У меня есть эти ошибки:

Путь JPA будет использовать Select new запрос. Вам нужен класс Java (не отображается JPA Entity) - часто называемый DTO, который содержит два поля empleadoIdcount и конструктор, которые принимают их

package com.example 
public class Dto { 
    private int empleadoId; 
    private long count; 

    public Dto(int empleadoId, long count) { 
     this.empleadoId = empleadoId; 
     this.count = count; 
    } 
    //getter and setter 
}

, то вы можете написать этот репозиторий метод:

@Query("SELECT new com.example.Dto(c.id_empleado, count(c)) " + 
     "from Cita c GROUP BY c.id_empleado ORDER BY c.fecha_hora") 
Map<Integer,Integer> statistics();

Примечание: Будьте осторожны, что c.id_empleado SNF c.fecha_hora должно совпадать с именем поля, а не столбец

Спасибо за ответ так быстро, но, хотя я применил ваше решение, теперь у меня другая проблема. Я редактировал вопрос. –

@ r.diazgoz: ваш probelm 'не смог разрешить свойство: empleado_id из: com.raquel.tfg.domain.Cita' - это то, что я нарисовал курсивом: вам нужно написать имя поля java вашего класса «Cita» (которые сопоставляются с столбцами) в запросе, но не имя столбцов! (Я могу написать запрос с правильными именами, потому что вы не разместили класс Cita) – Ralph
