Failed to convert property value of type java.lang.String to required type java.util.Date

Question

I'm getting this error when I try to input a date in a form. enter image description here

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>
        ...

In the controller I wrote the following with the same error (and different formats like "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));
}

I also tried to add annotation in class (as well with different formats) but same error

    ...
    @Column(name = "deadline")
    @DateTimeFormat(pattern = "dd/MM/yyyy")
    private Date deadline;
   ...

I think, I found out the error. I changed new SimpleDateFormat("dd/MM/yyyy") for new SimpleDateFormat("yyyy-MM-dd") — Joe

The pattern should be "yyyy-MM-dd". Careful with MM (months) and mm (minutes). — Luiggi Mendoza

simply add @DateTimeFormat(pattern = "yyyy-MM-dd") with (-)

example:

@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date dateNaissance;

You can also use: @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)

Add this in the controller. Change the dateFormat to your locale preference.

@InitBinder     
public void initBinder(WebDataBinder binder){
     binder.registerCustomEditor(       Date.class,     
                         new CustomDateEditor(new SimpleDateFormat("dd/MM/yyyy"), true, 10));   
}

Consider using this annotations in your model (Adapting format and TemporalType for your preferences)

@DateTimeFormat(pattern = "dd/MM/yyyy")
@Temporal(TemporalType.DATE)

How does this associate with the pattern parameter of @DateTimeFormat if you need to provide your own DateFormat to the CustomDateEditor binding?

borjab Over a year ago

@ DateTimeFormat might be helpfull if you cast the field to string again. For example. (Convert to XML, Json, etc) or just getting the property in the JSP @ Temporal will control if you store the field as a DATE or DATETIME field in the database.

@borjab, thanks a lot! I totally forgot about initBinder... You saved me a lot of time!

How do I use the InitBinder to register a custom editor for OffsetDateTime.class?

@DateTimeFormat(pattern = "yyyy-MM-dd")

Replace your format with this.

You can do this:

@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
private LocalDate myDate;

You need to change in BaseController for 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));
}

@InitBinder
    public void initBinder(WebDataBinder webDataBinder) {
    SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
    webDataBinder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));

Thanks for wanting to contribute. I should say that this suggestion comes late, though. Today no one should use neither Date class. They were both badly designed and have both been obsolete since java.time, the modern Java date and time API, came out on Java 8, which was 11 years ago.

You're right Well, it's in case someone uses very old versions and doesn't pay much attention.
