当我尝试在表单中输入日期时,我收到此错误。
TaskController
@RequestMapping(value = "/docreatetask", method = RequestMethod.POST)
public String doCreateTask(Model model, @Valid Task task,
BindingResult result, Principal principal,
@RequestParam(value = "delete", required = false) String delete) {
System.out.println(">TaskController doCreateTask " + task);
if (result.hasErrors()) {
System.out.println("/docreatetask in here");
model.addAttribute("task", task);
System.out.println("+++++"+task.getDeadline());// deadline is null
return "createtask";
}
...
Create.jsp
...
<form:form method="POST"
action="${pageContext.request.contextPath}/docreatetask"
commandName="task">
<table class="formtable">
<tr>
<td class="label">Task</td>
<td><form:input cssClass="control" path="taskname"
name="taskname" type="text" /><br />
<form:errors path="taskname" cssClass="error" /></td>
</tr>
<tr>
<td class="label">Description</td>
<td><form:textarea cssClass="control" path="description"
name="description"></form:textarea><br />
<form:errors path="description" cssClass="error" /></td>
</tr>
<tr>
<td class="label">Deadline (dd/mm/yyyy)</td>
<td><form:input cssClass="control" path="deadline"
name="deadline" type="date" /><br />
<form:errors path="deadline" cssClass="error"></form:errors></td>
</tr>
...
在控制器中我写了以下相同的错误(和不同的格式,如&#34; yyyy / MM / dd&#34;)
@InitBinder
public void initBinder(WebDataBinder webDataBinder) {
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
dateFormat.setLenient(false);
webDataBinder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}
我还尝试在类中添加注释(以及不同的格式)但是同样的错误
...
@Column(name = "deadline")
@DateTimeFormat(pattern = "dd/MM/yyyy")
private Date deadline;
...

在控制器中添加它。将dateFormat更改为您的区域设置首选项。
@InitBinder
public void initBinder(WebDataBinder binder){
binder.registerCustomEditor( Date.class,
new CustomDateEditor(new SimpleDateFormat("dd/MM/yyyy"), true, 10));
}
考虑在模型中使用此注释(根据您的偏好调整格式和TemporalType)
@DateTimeFormat(pattern = "dd/MM/yyyy")
@Temporal(TemporalType.DATE)
答案 1 :(得分:8)
只需添加@DateTimeFormat(pattern =“yyyy-MM-dd”)( - )
示例:
@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date dateNaissance;
答案 2 :(得分:0)
@DateTimeFormat(pattern = "yyyy-MM-dd")
以此替换格式。
