Mybatis学习第14节 -- 一级缓存被刷新的情况

测试

@Test
    public void testCacheLevelOne1() {
        SqlSession session = MyBatisUtil.getSqlSession();
        ShopMapper mapper = session.getMapper(ShopMapper.class);
        Shop shop = mapper.getShopById(1);
        System.out.println(shop);
        // update
        shop.setName("new "+shop.getName());
        mapper.updateShopBySet(shop);


//        session = MyBatisUtil.getSqlSession();
//        mapper = session.getMapper(ShopMapper.class);
//        // select again
        System.out.println(mapper.getShopById(1));
        session.close();
    }
