问题
I am building a web application using Thymeleaf and SpringBoot, I am new to both the technologies.
In my html file, there is a Date field as follows:
<input type="date" th:field="*{issueDate}" />
My model class has a field corresponding to issueDate as follows:
@NotNull(message = "Cannot be empty")
private Date issueDate;
When I input a date from the UI, I see the following exception in the browser:
Failed to convert property value of type [java.lang.String] to required type [java.util.Date] for property issueDate;
From my experience, I understand that the UI reads the property as a String, but the model expects a type Date due to which the error occurs. So I need to convert the String to a Date. However where should this be done? Since the error occurs even before the setter method in the model is invoked.
Any help would be much appreciated! Thanks in advance!

In your controller:
@InitBinder
public void initBinder(WebDataBinder binder) {
binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("MM/dd/yyyy"), true));
}
WHERE "MM/dd/yyyy" is the date format you're using.
