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

    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。

  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));
	}
