spring mvc - HTML form passing request parameter

Question

I started to learn Spring MVC and web development. I have this method in my Controller

@GetMapping("/deleteCar")
public String deleteCar(@RequestParam("carId") int carid) {
    carService.deleteCar(carid);
    return "redirect:/car/cars";
}

How can I pass the request parameter through html form ?

<section>
    <form action="${pageContext.request.contextPath}/car/deleteCar">
    <input type="text" id="deleteCarWithID" value="${carId}">

    </form>
</section>

I get this warning:

WARNING: Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required int parameter 'carId' is not present]

Thank you!

You are missing the name attribute so Mention name attribute with the parameter name in input field. Try below code for the same. Also add a submit type button to submit the form.

<input type="text" name="carId" id="deleteCarWithID" value="${carId}">
