java - 带有 Spring MVC 的 jQuery datepicker - 将日期从 View 传递到 Controller 发送 null

Question

提交表单后，我看到所有值都正确传递给了 Controller ，但传递为 null 的日期除外(表单中的日期选择在输入字段中输入了正确的日期)我尝试添加但没有帮助.我还尝试删除“路径”并将其替换为“”中的“名称”，但它会抛出错误，指出“路径”属性丢失。我尝试跟随但没有成功-
1. In spring web mvc application date value is received as NULL in controller after reading from date-picker on jsp page
2. http://blog.teamextension.com/date-binding-in-spring-mvc-1321

j查询: $(文档).ready(函数() { $("#datepicker").datepicker({dateFormat:"yy-mm-dd"}); });

JSP:

<div class="plLabelSearch" id="hiddenField">Due Date:</div> 
<div class="plinput"><form:input type="text" id="datepicker" path="dueDate" placeholder="yyyy-mm-dd"/></div>

型号:

@Column(name = "DUE_DATE")  
@DateTimeFormat(pattern = "yyyy/mm/dd")  
private Date dueDate;

Controller :

@RequestMapping(value="/lock", method = RequestMethod.POST)  
 public @ResponseBody Status lockDevice(@ModelAttribute("adminTransaction") @Validated AdminTransaction adminTransaction, BindingResult result, Model model, Locale locale,Map<String, Object> map, HttpServletRequest request) {
     try {
         /*.......CODE.........*/
         adminTransactionDO.setDueDate(adminTransaction.getDueDate());
        /*.......CODE.........*/
         }
         return new Status("success", "Transaction inserted Successfully !");  
          } catch (Exception e) {  
           return new Status("error", e.toString());  
          }
}

它看起来像你的:

@Column(name = "DUE_DATE")  
@DateTimeFormat(pattern = "yyyy/mm/dd")  
private Date dueDate;

是问题。 Spring 无法将其转换为日期。

改为尝试

 private String dueDate;
