我认为问题在于Spring在提交以下input字段时不知道如何反序列化浏览器客户端发送的日期
<tr name='tstest'> <td>Date Of Birth</td> <td><form:input path='dateOfBirth' name='timestamp' value=''/><a href='javascript:show_calendar(’document.tstest.timestamp’, document.tstest.timestamp.value);'><img src='https://www.6hehe.com/images/cal.gif' border='0' alt='Click Here to Pick up the timestamp'></a> </td></tr>
Spring不知道如何将您输入的值带入该字段并将其转换为Date对象。您需要为此注册一个propertyeditor。例如，将以下内容添加到您的@Controller课程中
@InitBinderpublic void initBinder(WebDataBinder binder) { SimpleDateFormat sdf = new SimpleDateFormat('MM/dd/yyyy'); sdf.setLenient(true); binder.registerCustomEditor(Date.class, new CustomDateEditor(sdf, true));}
显然，将更SimpleDateFormat改为客户端发送的内容。
在相关说明中，您通过发送重定向发送302响应
return 'redirect:/full-reg';
请记住，请求和模型属性仅在一个请求期间有效。因此，当您的客户将请求发送到时full-reg，您最初发送的表单输入参数不再存在。您应该重新考虑如何执行此操作。
解决方法我是Spring MVC的新手。运行项目时我被错误卡住 错误-客户端发送的请求在语法上不正确。我有一个实体类PatientInfo。我的jsp页面是demo1。我的控制器是患者控制器。我要实现的功能是将值插入数据库。但是我无法在控制器中调用我的函数（add-update2）。
