How can I mock a field in a Spring controller test using mockito?

Question

I'm trying to autowire a mocked DAO object for my Spring (v. 3.1.0.RELEASE) test and using Mockito 1.9.0. The controller class with the field I want to mock is

@Controller
@RequestMapping("/registrationform.jsp")
public class RegistrationController {

private static Logger LOG = Logger.getLogger(RegistrationController.class);

@Autowired
private RegistrationValidation registrationValidation;

@Autowired
private UsersDao usersDao;

I have this testApplicationContext.xml file ...

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

<context:component-scan base-package="com.myco.eventmaven" />

<!--  Mock object for the UsersDao -->
<bean id="usersDao" name="mockDao" class="org.mockito.Mockito" factory-method="mock"  >
    <constructor-arg value="com.myco.eventmaven.dao.UsersDao" />
</bean>

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/views/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="/WEB-INF/messages" />
</bean>

</beans>

Here's my Spring test ...

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "file:src/test/resources/testApplicationContext.xml" })
public class RegistrationControllerTest {

@Autowired
private ApplicationContext applicationContext;

@Autowired 
private RegistrationController controller;

private MockHttpServletRequest request;
private MockHttpServletResponse response;
private HandlerAdapter handlerAdapter;


@Before
public void setUp() {
    request = new MockHttpServletRequest();
    response = new MockHttpServletResponse();
    handlerAdapter = applicationContext.getBean(HandlerAdapter.class);
}

@Test
public void testShowRegistrationForm() throws Exception {
    request.setRequestURI("/user/registrationform.jsp");
    request.setMethod("GET");
    final ModelAndView mav = handlerAdapter.handle(request, response, controller);
    assertViewName(mav, "user/registrationform");
    // assertAndReturnModelAttributeOfType(mav, "image", Image.class);
}

And the spectacular error ...

How can I address this tragic error?

I assume you included this because of the springockito code? Is that the only way to fix this b/c of some bug with Spring? If you look at my application context code, I cut and pasted the other solution given in that answer. — Dave, Mar 13 '12 at 14:07
There were like 4-5 solutions in that thread, including springockito. — Dave Newton, Mar 13 '12 at 14:45

Before I switch to another framework, I was able to get this working using the solution outlined here -- http://blog.jayway.com/2011/11/30/spring-integration-tests-part-i-creating-mock-objects/.

From the error logs , i could see problem is with the usage of @autowired at different places.

Basically controller is injected into the container via @controller and component scan. Also xml config file misses the context: annotation config tag.

Ideally there is no need for @autowired to be used in the below statement.

 @Autowired 
 private RegistrationController controller;

How can I mock a field in a Spring controller test using mockito?
