Failed to check date in Spring MVC

Question

I use custom editors to convert String to date. My code is below

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

When I enter the date in "yyyy-MM-dd", then insert it.

But when I enter the empty, it throws an exception

The nested exception is java.lang.IllegalArgumentException: Failed to parse date: Unmatched date: ""

I can not confirm this.

If I give some other format, it will also not be able to parse.

When you create an instance of CustomDateEditor, the second parameter in your case should be true. True allows null values.
