insert pojo data into thymeleafe template wont work

This is my code below, and the response i get is.

Bummer! It looks like the page could not be found. Are you sure you added a method with the correct @RequestMapping annotation?

What am I missing?

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.RequestMethod;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.ui.ModelMap;

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

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

}
com/teamtreehouse/contactmgr/model/Contact.java 
package com.teamtreehouse.contactmgr.model;

public class Contact {
  private int id;
  private String firstName;
  private String lastName;
  private String email;

  public Contact() {}

  public Contact(int id, String firstName, String lastName, String email) {
    this.id = id;
    this.firstName = firstName;
    this.lastName = lastName;
    this.email = email;
  }

  public int getId() {
    return id;  
  }

  public String getFirstName() {
    return firstName;  
  }

  public String getLastName() {
    return lastName;  
  }

  public String getEmail() {
    return email;  
  }

  public void setId(int id) {
    this.id = id;  
  }

  public void setFirstName(String firstName) {
    this.firstName = firstName;  
  }

  public void setLastName(String lastName) {
    this.lastName = lastName;  
  }

  public void setEmail(String email) {
    this.email = email;
  }
}

This is case where your solution is one you'd use in most real-world problems, but not quite what the challenge is asking for. Which is to render the template for the specific path "/contact", not "contact/{id}"

Do you mean changing the line @RequestMapping(value = "/contact/{id}") to @RequestMapping(value = "/contact") This gives me the same error. There must be something else missing.

ok so using just what is below will work and got me passed this. Far less complicated than I though.

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