@Table("selection_image")
@TableIndexes({ @Index(name = "si_id_index", fields = { "selectionId" }, unique = true) })
public class SelectionImage extends DataBaseEntity implements Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 4941654523615799149L;

	@Id
	private long id;

	@Column(hump = true)
	private long selectionId;

	@Column
	private InputStream image;

	public SelectionImage() {
		super();
	}

	public SelectionImage(long selectionId, InputStream image) {
		super();
		this.selectionId = selectionId;
		this.image = image;
	}

	public long getId() {
		return id;
	}

	public void setId(long id) {
		this.id = id;
	}

	public long getSelectionId() {
		return selectionId;
	}

	public void setSelectionId(long selectionId) {
		this.selectionId = selectionId;
	}

	public InputStream getImage() {
		return image;
	}

	public void setImage(InputStream image) {
		this.image = image;
	}

}

缓存后 获取数据报错
