capture a URI Parameter but no suitable constructor found for Contact(int).....

stuck in the mud, should i go with @autowired ? and @PathVariable ? Nothing worked....

com/teamtreehouse/contactmgr/controller/ContactController.java
package com.teamtreehouse.contactmgr.controller;
import com.teamtreehouse.contactmgr.model.Contact;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.ui.ModelMap;

@Controller
public class ContactController {
    @RequestMapping("/")
    public String home() {
      return "index";
    }

    @RequestMapping("/contact/{id}")
    public String contact(@PathVariable int id, ModelMap modelMap) {
      Contact c = new Contact(id);
      modelMap.put("contact",c);
      return "contact_detail";
    }
}

The solution is... 

@RequestMapping("/contact/{id}")
public String contact(@PathVariable int id,ModelMap modelMap) {
  Contact c = new Contact(id,"firstName","lastName","email");
  modelMap.put("contact",c);
  return "contact_detail";
}

Hey Jens, you are super close. Just remember when creating a new contact variable that it has one than one parameters in the construction, you passed id in just fine, just be sure to include the needed string as well. I believe it takes 3, but check in the contact.java file to make sure.

Yes thanks Rob Bridge, it worked but "don't worry about them" honestly makes no sense to me !?

What is the solution? I did not get yet..

package com.teamtreehouse.contactmgr.controller;

import com.teamtreehouse.contactmgr.model.Contact;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.ui.ModelMap;

@Controller
public class ContactController {
    @RequestMapping("/")
    public String home() {
      return "index";
    }

    @RequestMapping("/contact/{id}")
    public String contact(@PathVariable int id,ModelMap modelMap) {
      Contact c = new Contact(id);
      modelMap.put("contact",c);
      return "contact_detail";
    }
}

I dont know what to change in contact.java file.

Regards,

Thomas
