当我尝试在表单中输入日期时收到此错误。
任务控制器
@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";
}
...
创建.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,我编写了以下内容,但出现相同的错误(以及不同的格式,如“yyyy/MM/dd”)
@InitBinder
public void initBinder(WebDataBinder webDataBinder) {
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
dateFormat.setLenient(false);
webDataBinder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}
我也尝试在类中添加注释(以及不同的格式)但同样的错误
...
@Column(name = "deadline")
@DateTimeFormat(pattern = "dd/MM/yyyy")
private Date deadline;
...
只需添加 @DateTimeFormat(pattern = "yyyy-MM-dd") 和 (-)
示例:
@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date dateNaissance;
将其添加到控制器中。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(根据您的喜好调整格式和 TemporalType)
@DateTimeFormat(pattern = "dd/MM/yyyy")
@Temporal(TemporalType.DATE)
@DateTimeFormat(pattern = "yyyy-MM-dd")
用此替换您的格式。
你可以这样做:
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
private LocalDate myDate;
您需要在 BaseController 中更改 initBinder
@InitBinder
protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) {
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
dateFormat.setLenient(false);
binder.registerCustomEditor(Date.class, null, new CustomDateEditor(dateFormat, true));
}
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
谢谢,它对我有用!
