The type ManagedBean is deprecated

Question

I just created a new maven project and Added a index controller. Then I used managedbean annotation. But I get this message The type ManagedBean is deprecated. So I tried for alternatives but I could not find any solutions. All the articles uses @ManageBean. So I think am missing something here.

My pom.xml file

</project>  

and IndexController

package asf.asdflksdfklj.Controller;

import javax.faces.bean.ManagedBean;


@ManagedBean
public class IndexController {

    public String showHello(){
        return "hello world";
    }

}

Is it really ManagedBean deprecated? If so what should I use to make this code work?

Solution

Managed beans are being deprecated and replaced with CDI beans. You will eventually have to upgrade to CDI, so might as well start now.

Instead of @ManagedBean, if you use @Named and put cdi-api-1.2.jar in your dependency, you should be good to go:

import javax.inject.Named;
import javax.enterprise.context.SessionScoped;

@Named
@SessionScoped
public class IndexController implements Serializable {

}
