Question

Hi I am creating a spring mvc app. The spring context seems to be mapping the controller methods to wrong urls.

I’ve following controllers:

HelloWorldController

package com.springapp.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/hello")
public class HelloWorldController {

    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView helloWorld() {

        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message);
    }
}

ContactsController

package com.springapp.controller;

import com.springapp.form.Contact;
import com.springapp.service.ContactService;

import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
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
@RequestMapping("/contacts")
public class ContactsController {

    @Autowired
    private ContactService contactService;

    @RequestMapping(method = RequestMethod.GET)
    public String listContacts(Model map) {

        map.addAttribute("contact", new Contact());
        map.addAttribute("contactList", contactService.listContacts());

        return "contact";
    }

    @RequestMapping(value="{contactId}", method=RequestMethod.GET)
    public String showContact(@PathVariable("contactId") Integer contactId) {

        contactService.getContact(contactId);
        return "redirect:/contacts";
    }

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

        contactService.addContact(contact);
        return "redirect:/contacts";
    }

    @RequestMapping("/{contactId}/delete")
    public String deleteContact(@PathVariable("contactId") Integer contactId) {

        contactService.removeContact(contactId);
        return "redirect:/contacts";
    }
}

However the spring context is mapping them as:

INFO: Mapped URL path [/contacts/new] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/new.*] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/new/] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/addContact] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/addContact.*] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/addContact/] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/delete/{contactId}] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/delete/{contactId}.*] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/delete/{contactId}/] onto handler 'contactsController'
INFO: Mapped URL path [/hello] onto handler 'helloWorldController'
INFO: Mapped URL path [/hello.*] onto handler 'helloWorldController'
INFO: Mapped URL path [/hello/] onto handler 'helloWorldController'

Where is it getting these new and addContact patterns? Also the mapping /contacts is missing.

Your problem could depend on mappings you had in a old version of your application.
Try to update the deployed version in Tomcat.

If you are using Eclipse to run/debug your project try to clean/compile your projet and than to deploy the new version in Tomcat.
