Question

I use org.springframework.web.jsf.el.SpringBeanFacesELResolver in my JSF + Spring application. Every backing bean needs an interface to be resolved. I guess that it’s interface type of dependency injection.

#{bean.text}

public interface IBean {
    String getText();
}

@Named
@Scope("session")
public class Bean implements IBean {
    public String getText() {
        return "Hello World!";
    }
}

I would like to get rid of the interface. It’s kind of bureaucracy for me. Is it possible?

I finally solved it. The problem was in beans with scope depending on HTTP (request, session). By default interfaces should be manually created. This can be avoided by using proxies.

If using component scan:

<context:component-scan base-package="..." scoped-proxy="targetClass" />

Or in bean definition:

<bean ...>
    <aop:scoped-proxy>
</bean>

See chapter 4.5.4.5 Scoped beans as dependencies in Spring documentation. http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/beans.html
