java ee spring错误

Question

I am facing a problem, It doesn't redirect to a jsp(HTTP 404) from the controller although I entered correctly a valid url address that can be treated by the controller. Here is my web.xml , the controller and what the debugger shows me.

I entered http://localhost:8080/AccessControl/produits.aspx

</web-app>

AgentAdministrativeController.java in the controller package

package controller;

import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import dao.AgentAdministrative;
import services.AgentAdministrativeMetier;
import services.SessionBean;

public class AgentAdministrativeController {

    @Autowired
    AgentAdministrativeMetier services;

    @Autowired
    private SessionBean sessionBean;

    @RequestMapping(value={"/connnexiontrait","/default"})
    public String verifier(Model model,@RequestParam String username,@RequestParam String motdepasse,@RequestParam int labo){
        Long t;
        String arg1;

        t=services.verifaccess(username, motdepasse, labo);

        if (t.intValue()==0)
        {
            arg1="Nom d'utilisateur ou mot de passe ou numero de laboratoire sont incorrectes ,veuillez les ressaisir " ;
            model.addAttribute("erreurs", arg1);
            System.out.println("succes");
            return "connexion";
        }
        else
        {
            System.out.println("succes");
            return "produits";
        }
    }

    @RequestMapping(value={"/produits"})
    public String verifie(Model model)
    {   
        return "produits";
    }
}

This is what Debugger shows me.

Answer 1

There are couple of issues with your controller.

1. Your controller is missing @Controller annotation.

2. Your application-servlet-config.xml does not have spring mvc elements, hence your controller is not even being picked up when server starts. You can controller mapping in your logs, if its picked up.

So try using the below application-servlet-config.xml instead and see. I would also suggest seeing a spring mvc tutorial, if this does not resolve it.
