美好的一天。我是JSP的初学者，我将每日销售监控作为一个项目。我已经完成了我的研究，并且我已经制作了我的第一个CRUD jsp程序函数，但是当我添加了很多列时，插入不起作用（删除和查看仍然有效）。没有可见错误，但只要在读取页面上重定向，就不会加载最新数据。
我尝试在所有角度寻找错误，但我似乎无法找到它。我尝试计算所有列，重命名一些实例，但它仍然无法运行。你能解决我的问题吗？这是我第一次问这里，我似乎无法找到前面问题的答案。所有回复都将受到赞赏。
顺便说一句，我使用的是Netbeans IDE 8.1和Microsoft SQL Server

我解决了自己的问题，而且这似乎只是我的粗心大意。

Shift:

我包含了选项价值＆＃34; World＆＃34;和＆＃34; Tech＆＃34; （这是我在互联网上找到的代码的一部分）即使列的定义＆＃34; shift＆＃34;在数据库上是varchar（2）
我很抱歉把时间花在琐碎的事情上。祝你有个美好的一天。
