fetch URL parameter using spring mvc

Question

I want to fetch url parameter in my class. my application based on Spring MVC.

While calling url: http://localhost:8080/mywebapp/dir/register.do?id=26 it gives error 400

@RequestMapping(value = "/register")
public ModelAndView finalPage(@PathVariable("id") Long id) throws NumberFormatException, Exception {
   // code...
}

Anybody can solve my problem.

How do you think @PathVariable works and why?

Use @QueryParam instead of @PathVariable

You say

I want to fetch url parameter in my class

but you are using @PathVariable which

indicates that a method parameter should be bound to a URI template variable

You don't have a uri template variable called id in your mapping.

What you really need is a @RequestParam. The documentation explains how to use it.

Thanks @SotiriosDelimanolis, I used "@RequestParam" and its work perfect. but what if i did not pass id in url? in some cases i am not passing parameter with url

@Bharat If you look at the javadoc I linked, you can set required to false.
