Итак, у меня есть компания, я имею ошибку при каждом добавлении компании. Я использую PostgreSQL для моей базы данных, и я использую литералы двойных кавычек для сопоставления столбцов таблицы в паскальде.Имя столбца X не найдено в этом ResultSet - JPA
лицо Компания:
@Entity
@XmlRootElement
public class Company {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="\"Id\"")
private Long id;
@Column(name="\"Name\"")
private String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Компания Endpoint:
@Stateless
@Path("/companies")
public class CompanyEndpoint {
@PersistenceContext(unitName = "primary")
private EntityManager em;
@POST
@Consumes("application/json")
public Response create(Company entity) {
em.persist(entity);
return Response.created(
UriBuilder.fromResource(CompanyEndpoint.class)
.path(String.valueOf(entity.getId())).build()).build();
}
@DELETE
@Path("/{id:[0-9][0-9]*}")
public Response deleteById(@PathParam("id") Long id) {
Company entity = em.find(Company.class, id);
if (entity == null) {
return Response.status(Status.NOT_FOUND).build();
}
em.remove(entity);
return Response.noContent().build();
}
@GET
@Path("/{id:[0-9][0-9]*}")
@Produces("application/json")
public Response findById(@PathParam("id") Long id) {
TypedQuery<Company> findByIdQuery = em
.createQuery(
"SELECT DISTINCT c FROM Company c WHERE c.id = :entityId ORDER BY c.id",
Company.class);
findByIdQuery.setParameter("entityId", id);
Company entity;
try {
entity = findByIdQuery.getSingleResult();
} catch (NoResultException nre) {
entity = null;
}
if (entity == null) {
return Response.status(Status.NOT_FOUND).build();
}
return Response.ok(entity).build();
}
@GET
@Produces("application/json")
public List<Company> listAll(@QueryParam("start") Integer startPosition,
@QueryParam("max") Integer maxResult) {
TypedQuery<Company> findAllQuery = em
.createQuery("SELECT DISTINCT c FROM Company c ORDER BY c.id",
Company.class);
if (startPosition != null) {
findAllQuery.setFirstResult(startPosition);
}
if (maxResult != null) {
findAllQuery.setMaxResults(maxResult);
}
final List<Company> results = findAllQuery.getResultList();
return results;
}
@PUT
@Path("/{id:[0-9][0-9]*}")
@Consumes("application/json")
public Response update(@PathParam("id") Long id, Company entity) {
if (entity == null) {
return Response.status(Status.BAD_REQUEST).build();
}
if (id == null) {
return Response.status(Status.BAD_REQUEST).build();
}
if (!id.equals(entity.getId())) {
return Response.status(Status.CONFLICT).entity(entity).build();
}
if (em.find(Company.class, id) == null) {
return Response.status(Status.NOT_FOUND).build();
}
try {
entity = em.merge(entity);
} catch (OptimisticLockException e) {
return Response.status(Response.Status.CONFLICT)
.entity(e.getEntity()).build();
}
return Response.noContent().build();
}
}
Последнее, что я вижу это org.postgresql.util.PSQLException: The column name "Id" was not found in this ResultSet.
Может кто-то объяснить, что неправильно в моем коде. Заранее спасибо.

Вы можете заключить, что PostgreSQL DEFAULTS в «нижнем регистровом» названии столбцов, ЕСЛИ ВЫ НЕ ОТМЕТЬТЕ ИХ. Некоторые поставщики JPA предоставляют удобную настройку для автоматической подписи для вас. –
Просто не помещайте кавычки вокруг имен столбцов. –
