Just customized the above code in order to adjust to Spring Boot, if you want to explicit trim function for some fields in the form, you can show them as below:

        public void initBinder(WebDataBinder binder) {
          binder.registerCustomEditor(String.class, new StringTrimmerEditor(true));
          binder.registerCustomEditor(String.class, "userDto.username", new StringTrimmerEditor(false));
          binder.registerCustomEditor(String.class, "userDto.password", new DefaultStringEditor(false));
          binder.registerCustomEditor(String.class, "passwordConfirm", new DefaultStringEditor(false));
        }
}
