【问题描述】：
美好的一天。我是 JSP 的初学者，我将日常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 程序功能，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）。没有可见的错误，但是一旦在读取页面上重定向，就不会加载最新的数据。
我尝试从各个角度寻找错误，但我似乎无法找到它。我尝试计算所有列，重命名了一些实例，但它仍然无法正常工作。你能帮我解决我的问题吗？这是我第一次在这里问，我似乎无法找到以前问题的答案。我们将不胜感激所有回复。
顺便说一下，我使用的是 Netbeans IDE 8.1 和 Microsoft SQL Server

}【问题讨论】：
-
任何异常抛出？
-
投票结束。 “插入不起作用”不够详细，无法帮助诊断问题。
-
@MaVRoSCy - 没有，只是插入不会像刚才那样发生。
-
你调试过你的程序吗？它在哪里停止执行？
-
抱歉回复晚了。我做到了，它构建成功。
