我尝试将Spring查询与命名实体图一起用于方法getAll，我收到以下错误：

我的课程是租来的，看起来像这样：
@Entity
@Table(name="rented")
@NamedEntityGraphs({
@NamedEntityGraph(name = "rentedMovieClient", attributeNodes = {
@NamedAttributeNode("client"),
@NamedAttributeNode("movie")
})
})
public class Rented implements Serializable{
@Id
@TableGenerator(name = "TABLE_GENERATOR", initialValue = 0, allocationSize = 1)
@GeneratedValue(strategy = GenerationType.TABLE, generator = "TABLE_GENERATOR")
@Column(unique = true, nullable = false)
private Integer id;
@ManyToOne(optional = false, fetch = FetchType.LAZY)
@JoinColumn(name = "client_id")
private Client client;
@ManyToOne(optional = false, fetch = FetchType.LAZY)
@JoinColumn(name = "movie_id")
private Movie movie;
public Rented() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Client getClient() {
return client;
}
public void setClient(Client client) {
this.client = client;
}
public Movie getMovie() {
return movie;
}
public void setMovie(Movie movie) {
this.movie = movie;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Rented rented = (Rented) o;
// if (!id.equals(rented.id)) return false;
if (!client.equals(rented.client)) return false;
return movie.equals(rented.movie);
}
@Override
public int hashCode() {
int result = id.hashCode();
// result = 31 * result + client.hashCode();
// result = 31 * result + movie.hashCode();
return result;
}
}
我的repo界面如下所示：
public interface GraphRepo extends JpaRepository<Rented, Integer>, CustomRepo{
@Query("select r from Rented r")
@EntityGraph(value = "rentedMovieClient", type = EntityGraph.EntityGraphType.LOAD)
List<Rented> findAllS();
@Query("select r from Rented r where r.movie.id = ?1")
@EntityGraph(value = "rentedMovieClient", type = EntityGraph.EntityGraphType.LOAD)
List<Rented> findAllMovie(Integer movieId);
@Query("select r from Rented r where r.client.cnp = ?1")
@EntityGraph(value = "rentedMovieClient", type = EntityGraph.EntityGraphType.LOAD)
List<Rented> findAllClient(Integer clientId);
}
我在网上看到查询或命名约定可能存在问题，但我发现它没有任何问题。有任何想法吗？我也有一个repo的实现，但它与其他东西，而不是相关。数据库有问题吗？
