读示例
@Test
public void testMSWrite(){
Order order = new Order();
order.setUserId(1l);
order.setOrderId(1l);
order.setTitle("测试，userId:"+order.getUserId() + " orderId:" + order.getOrderId());
order.setContent(order.getTitle());
orderMapper.insert(order);
}
写示例
@Test
public void testMSRead(){
OrderExample ex = new OrderExample();
ex.createCriteria().andUserIdEqualTo(1l);
List<Order> orders = orderMapper.selectByExample(ex);
if(CollectionUtils.isEmpty(orders)){
System.out.println("查询结果集为空");
return;
}
orders.stream().forEach(o->{
System.out.println("userId:"+o.getUserId() + " orderId:" + o.getOrderId());
});
}
