dependency injection question from factory-method

If a bean is using setter based DI for a particular attribute and the attribute ref is to a factory-method that has a scope of 'request', will that factory-method be called each time the bean is used or will the factory-method be called only once when the bean is initialized at context startup?

Code:

---

    <!--bean id="fooBean"
          scope="request"
          factory-bean="someFactoryBean"
          factory-method="getObject">
    </bean-->

    <bean id="someController"
          <property name="foo" ref="fooBean" />
        ......
      </bean>

---

So I would expect that the fooBean.getObject() would be called for each new invocation of someController within a Request but I do not see that happening. It appears as though foo is set on someController only once (at the Bean Container startup).

Am I expecting the wrong behavior?

How to write a JUnit Test case for following code.?

package net.*;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HelloWorldController implements Controller {

public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {

String Mess = "Hello";

ModelAndView modelAndView = new ModelAndView("hello");
modelAndView.addObject("message", Mess);

return modelAndView;
}
}

I suggest a read of the reference guide and how to use scoped beans with dependency injection and how they work. In short you get a proxied object which does the lookup, so injection is once but delegated at runtime, however your configuration is flawed (check the reference guide for that).
