Java spring mvc中的双精度、日期未绑定

我正在尝试使用SpringWeb提交表单，在提交时填写数据后，我的金额、地址、createdDate都为空。不明白为什么只有这些值没有进入控制器

registerUser.jsp页面：

<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>    
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>    
  
       <form:form method="post" action="registerUser" modelAttribute="user">    
        <table > 
        <tr>    
          <td>ID : </td>   
          <td><form:input path="id"  /></td>  
         </tr>    
         <tr>    
          <td>First Name : </td>   
          <td><form:input path="firstName"  /></td>  
         </tr> 
          <tr>    
          <td>Last Name : </td>   
          <td><form:input path="lastName" /></td>  
         </tr>     
         <tr>    
          <td>Amount Given :</td>    
          <td><form:input path="amount" /></td>  
         </tr>   
         <tr>    
          <td>Phone :</td>    
          <td><form:input path="phone" /></td>  
         </tr> 
         <tr>    
          <td>Address :</td>    
          <td><form:input path="address" /></td>  
         </tr>  
         <tr>    
          <td>Account Created Date :</td>    
          <td><form:input path="createdDate" type="date"/></td>  
         </tr>     
         <tr>    
          <td colspan="2"><input type="submit" value="Save" /></td>    
         </tr>    
        </table>    
       </form:form>
