        throws Exception {
    String param_error = null;
    VehicleSearch vehicleSampling = (VehicleSearch) command;
    System.out.println(vehicleSampling.getRegDateFrom());

on print it gives null

Answer 1

You need to have

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

and instead of "sql.date" use "util.date"

Also try by removing property "readonly"

Answer 2

我猜您需要删除“ ReadOnly = true”，如果将readOnly设置为true，则该值将不会与请求一起传递。
