为什么jsp页面中的多个表单导致spring混淆

标签： java spring jsp spring-mvc

我是Spring MVC的新手，我找到了让我做基本的教程的教程。但是，当我尝试在一个jsp页面中的多个表单上执行它时，它不起作用。每当我点击人体测量数据表单上的“保存”按钮时，它会显示“vitalsigns”模型属性的illegalstateexception错误。每当我点击生命体征表单上的“保存”按钮时，它会显示“anthropometricdata”模型属性的非法状态异常错误。当我有正确的请求映射时，我不明白为什么Spring会感到困惑。

我尝试在我的所有ModelAttributes中添加（“nameofmodelattribute”），但它仍然没有帮助。

虽然当我删除其他表格并仅留下人体测量数据表单时，它仍然有效。我似乎无法弄清楚这是怎么回事。

这是显示的完整错误：

HTTP Status 500 - An exception occurred processing JSP page /WEB-INF/view/itr.jsp at line 10

首先，我要感谢所有试图提供帮助的人，但我已经找到了问题。

当我点击＆＃34;保存＆＃34;在一种形式中，它进入doActions方法，而在doActions方法中，其他模型不再是map.put，就像在setupForm方法中看到的那样。这就是我的控制器类现在所看到的：
