Get last part of URL path

Question

I'm trying to get the last string after user with this request handler. Is it possible to do this without being hacky?

 @Controller
 @RequestMapping("/user/*")
 public class Student{
      @RequestMapping(method = RequestMethod.GET)
      public String getUser(ModelMap model, /*, parameter that gets user id */) {
          // function that gets user id
          model.addAttribute("foo", "foo");
          return "bar";
      }
}

Answer 1

Spring has @PathVariable for the same.

@Controller
 public class Student{
      @RequestMapping("/user/{id}")
      public String getUser(ModelMap model, @PathVariable String id) {
          // function that gets user id
          model.addAttribute("foo", "foo");
          return "bar";
      }
}

Here I have assumed that user id is of String type, you may change the type of id as per your need.

Answer 2

Try to use @RequestParam like this:

  @Controller
  public class Student{
  @RequestMapping(value="/user/{user_id}", method = RequestMethod.GET)
  public String getUser(ModelMap model, @RequestParam(value="user_id") Long user_id){
      // function that gets user id
      model.addAttribute("foo", "foo");
      return "bar";
  }
}

Or use @PathVariable :

 @Controller
  public class Student{
  @RequestMapping(value="/user/{user_id}", method = RequestMethod.GET)
  public String getUser(ModelMap model, @PathVariable("user_id") Long user_id){
      // function that gets user id
      model.addAttribute("foo", "foo");
      return "bar";
  }
}
