Spring MVC HTTP 404 error

Question

I learning SpringMVC so I am followed Spring 3.0 MVC Series from HERE.

As you can see, I completed Part1, Part2, and I am right now on Part3 where I am learning how to handle forms with Spring 3 MVC.

But I get this HTTP 404 eror, when I try to run my application. Project strucutre and this error you can see at image below.

How I can fix this?

ContactController.java code:

package net.viralpatel.spring3.controller;

import net.virtalpatel.spring3.form.Contact;

import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;

@Controller
@SessionAttributes
public class ContactController {

@RequestMapping(value = "/addContact", method = RequestMethod.POST)
public String addContact(@ModelAttribute("contact")
Contact contact, BindingResult result) {

    System.out.println("First Name:" + contact.getFirstname() + 
                "Last Name:" + contact.getLastname());

    return "redirect:contacts.html";
}

@RequestMapping("/contacts")
public ModelAndView showContacts() {

    return new ModelAndView("contact", "command", new Contact());
}}

Answer 1

Just change contact to contacts

change

return new ModelAndView("contact", "command", new Contact());

to

return new ModelAndView("contacts", "command", new Contact());

The issue is in your forward it will check for the contact.jsp but actually you have contacts.jsp (you have suffix property as .jsp )

Answer 2

localhost:8080/Spring3MVC/index.jsp As you can see, I try first to open index.jsp and then redirect to contact.jsp – Zookey 44 mins ago

I think you have it mixed up. 1) There is a typo, you say contact.jsp but the file name is contacts.jsp (file name in eclipse) 2) Where is the contacts.html file ? I would suggest, you first return to the jsp and see if you can get your controller to return the jsp after that try redirecting to the html file after you create one.

Answer 3

your index.jsp is forwarded to contacts.html.

But you spring configuration does not have mapping for /contacts.html, you have mapped /contacts instead.

You need to change the /contacts mapping to

@RequestMapping("/contacts.html")
public ModelAndView showContacts() {
    return new ModelAndView("contact", "command", new Contact());
}
