问题如上
代码如下：

@Table("PlayerShoppingNum")
@PK(value = { "id,period,goodsId" })
public class PlayerShoppingNum {
	/*** id**/
	@Column("id")
	@Comment("id")
	private int id;
。。。。

           PlayerShoppingNum playerShoppingNum = playerShoppingManager.getPlayerShoppingNum(1, goodsId, periodId);
			playerShoppingNum.setPlayerId(playerId);
			playerShoppingNum.setShoppingId(shoppingId);
			 dao.update(playerShoppingNum);
