服务器错误500
2 个答案
lzqcdlxhy 跳转到问题位置 答案时间：2023-05-07 老哥，你数据库用的是不是mysql8.0的版本。我把8.0卸载换成站长的版本，再点击支付页面就没有500的报错了，而且没换之前点击 ‘立即购买’ 也有bug，第一次点报错，返回再点击‘立即购买’就出现订单页面了。排查了好久。。。
how2j 跳转到问题位置 答案时间：2021-06-05 根据报错你的OrderDAO 第95行报错空指针异常，看看具体是什么数据没有导致的呢？

Lz2848509 跳转到问题位置 答案时间：2020-04-27 是的 我还有一个问题是List<OrderItem> ois= (List<OrderItem>) request.getSession().getAttribute("ois");
为什么可以从session获取ois 我们之前好像并没有把他存到session里去
how2j 跳转到问题位置 答案时间：2020-04-26 payedInfoPrice 这个貌似忘记写 </span> 收尾了
how2j 跳转到问题位置 答案时间：2020-04-26 后面跟了参数就可以传递过去了。
Lz2848509 跳转到问题位置 答案时间：2020-04-25 同时好像实付款里的 span.payedInfoPrice 没有/span
