我需要一个spring存储库方法,可以让我使用id列表来获取一个Scene实体列表。当我尝试引用场景ID时,出现错误,称它无法找到名为IdScene的属性。我正在使用自定义查询来执行此操作。我的查询有问题吗?Spring JPA存储库查询找不到ID属性
我的实体是
public class Scene implements Serializable
{
private long id_scene;
private Media media;
private int sceneNumber;
private int version;
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "id_scene")
public long getIdScene() {
return id_scene;
}
public void setIdScene(long id_scene) {
this.id_scene = id_scene;
}
@ManyToOne
@JoinColumn(name = "id_media")
public Media getMedia() {
return this.media;
}
public void setMedia(Media media) {
this.media = media;
}
private List<Thumbnail> thumbnails = new ArrayList<Thumbnail>();
@OneToMany(mappedBy = "scene", cascade=CascadeType.ALL,
orphanRemoval=true)
@LazyCollection(LazyCollectionOption.FALSE)
public List<Thumbnail> getThumbnails() {
return this.thumbnails;
}
public void setThumbnails(List<Thumbnail> thumbnails) {
this.thumbnails = thumbnails;
}
public void addThumbnail(Thumbnail thumbnail) {
thumbnail.setScene(this);
this.thumbnails.add(thumbnail);
}
private Property property;
@OneToOne(mappedBy="scene", cascade=CascadeType.ALL,
orphanRemoval=true)
@LazyCollection(LazyCollectionOption.FALSE)
public Property getProperty() {
return property;
}
public void setProperty(Property property) {
this.property = property;
}
public void addProperty(Property property) {
property.setScene(this);
this.property = property;
}
@Column(name = "sceneNumber")
public int getSceneNumber() {
return sceneNumber;
}
public void setSceneNumber(int sceneNumber) {
this.sceneNumber = sceneNumber;
}
@Column(name = "version")
public int getVersion() {
return version;
}
public void setVersion(int version) {
this.version = version;
}
}
我的资料库:
public interface SceneRepository extends JpaRepository<Scene, Long> {
public final static String FIND_BY_ID_LIST = "SELECT s"
+ " FROM Scene s WHERE s.IdScene IN (:id)";
@Query(FIND_BY_ID_LIST)
public List<Scene> findByIdScene(@Param("id") List<Long> id);//, Pageable page);
}
尝试'SELECT期从场景S其中s.idScene IN(:ID)'注意小写的 'i' 在 'idScene' – 2013-03-17 10:21:46
@GarethDavis:这应该是一个答案。 – 2013-03-17 10:22:19
谢谢就是这样。为什么我需要使用小写字母? – user1988235 2013-03-17 12:03:45
