两种数组，注意用法

1、vo里面定义的方法  前端都是传数组。唯一区别是在 setShopId 方法里面

?

1 2 3 4 5 6 7 8 9

public void setShopId(Long  shopId) {     if(shopId != null && shopId != 0L){         setShopIds(shopId);     } }   public void setShopIds(Long ... shopIds) {     this.shopIds = shopIds; }

2、vo里面定义的方法  前端都是传数组。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

public void setShopId(Long  shopId) {       if(shopId != null && shopId != 0L){           Long[] shopIds = new Long[]{shopId};           setShopIds(shopIds);       }   }       public void setShopIds(Long[] shopIds) {       this.shopIds = shopIds;   }     public static void main(String[] args) {       Long shopId = 1L;       Long[] shopIds = new Long[]{shopId};       System.out.println(JSON.toJSONString(shopIds));   }
