更新數據庫出現問題java.lang.AssertionError: expected:<1> but was:<0>

運行測試案例，看到errors為0，還以為穩了，結果看數據庫信息，卻沒有更新。

回來查看，

出現問題java.lang.AssertionError: expected:<1> but was:<0>

console信息如下：

2019-04-22 21:30:18.710 [main] DEBUG com.imooc.o2o.dao.ShopDao.updateShop - ==>  Preparing: update tb_shop SET shop_name=?, shop_desc=?, shop_addr=?, last_edit_time=? where shop_id=? 
2019-04-22 21:30:18.753 [main] DEBUG com.imooc.o2o.dao.ShopDao.updateShop - ==> Parameters: 測試的店鋪(String), 測試描述(String), 測試地址(String), 2019-04-22 21:30:18.255(Timestamp), 1(Long)
2019-04-22 21:30:18.753 [main] DEBUG com.imooc.o2o.dao.ShopDao.updateShop - <==    Updates: 0

又查看了測試案例和數據庫，發現測試案例中的字段在數據庫中並沒有出現。修改了測試案例，

    @Test
    public void testUpdateShop() {
        Shop shop = new Shop();
        shop.setShopId(1L);
        shop.setShopName("測試的店鋪");
        shop.setShopDesc("測試描述");
        shop.setShopAddr("測試地址");
        shop.setLastEditTime(new Date());
        int effectedNum = shopDao.updateShop(shop);
        assertEquals(1, effectedNum);
    }

與數據庫對應后再運行。穩了。
