Could you help my web flow run? I'm a newbie.

I've spent more than three hours to figure out what is the problem, but I couldn't find it.

I've learned how to use SpringMVC and made a sample web application.

However, when I tried to integrate the web flow concept to the original spring mvc(which means, add webflow configuration to the dispacher context), I got this problem.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webflowContextConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.webflow.executor.FlowExecutor edu.sscrg.wmfs.web.config.WebflowContextConfiguration.flowExecutor;

My WebModelFactoryServiceInitializer.java, which is dispacher initializer is

public class WebModelFactoryServiceInitializer implements WebApplicationInitializer {

	private static final String DISPATCHER_SERVLET_NAME = "dispatcher";

	public void onStartup(ServletContext servletContext) throws ServletException {
		registerDispatcherServlet(servletContext);
	}
	
	private void registerDispatcherServlet(ServletContext servletContext) {
		AnnotationConfigWebApplicationContext dispacherContext = 
				createContext(WebMvcContextConfiguration.class, WebflowContextConfiguration.class);
		ServletRegistration.Dynamic dispatcher;
		dispatcher = servletContext.addServlet(DISPATCHER_SERVLET_NAME, new DispatcherServlet(dispacherContext));
		dispatcher.setLoadOnStartup(1);
		dispatcher.addMapping("/");
	}
	
	private AnnotationConfigWebApplicationContext createContext(final Class<?>... annotatedClasses) {
		AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
		context.register(annotatedClasses);
		return context;
	}
	
}

My WebflowContextConfiguration is

@Configuration
@ImportResource("classpath:/webflow_config/webflow-config.xml")
public class WebflowContextConfiguration {

	@Autowired
	private FlowExecutor flowExecutor;
	@Autowired
	private FlowDefinitionRegistry flowRegistry;
	
	@Autowired
	private LocaleChangeInterceptor localeChangeInterceptor;

	@Bean
	public FlowHandlerAdapter flowHandlerAdapter() {
		FlowHandlerAdapter flowHandlerAdapter = new FlowHandlerAdapter();
		flowHandlerAdapter.setFlowExecutor(flowExecutor);
		return flowHandlerAdapter;
	}

	@Bean
	public FlowHandlerMapping flowHandlerMapping() {
		FlowHandlerMapping flowHandlerMapping = new FlowHandlerMapping();
		flowHandlerMapping.setInterceptors(new Object[] { localeChangeInterceptor });
		flowHandlerMapping.setFlowRegistry(flowRegistry);
		return flowHandlerMapping;
	}
	
}

My webflow-config.xml is

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:webflow="http://www.springframework.org/schema/webflow-config"
  xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
           http://www.springframework.org/schema/webflow-config http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd">

  <webflow:flow-executor id="flowExecutor"/>
  
  <webflow:flow-registry id="flowRegistry" base-path="/WEB-INF/view" flow-builder-services="flowBuilderServices">
    <webflow:flow-location-pattern value="/**/*-flow.xml" />
  </webflow:flow-registry>

  <webflow:flow-builder-services id="flowBuilderServices" view-factory-creator="mvcViewFactoryCreator" conversion-service="conversionService" validator="validator" development="true" />

  <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />

  <bean id="mvcViewFactoryCreator" class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
    <property name="viewResolvers">
      <list>
        <ref bean="tilesViewResolver"/>
        <ref bean="viewResolver"/>
      </list>
    </property> 
  </bean>

  <bean id="conversionService" class="org.springframework.binding.convert.service.DefaultConversionService">
      <constructor-arg ref="mvcConversionService"/>
    </bean>
</beans>

Should there be more code or configuration to autowire the flowExecutor and flowRegistry in the WebflowContextConfiguration.java configuration?
I tried to modify the sample code from Pro SpringMVC: with Web Flow (http://www.apress.com/9781430241553): chapter 11 sample code(I attached the sample code, it is built with gradle). The sample code works well with the same code, but mine doesn't work. I want to know what I have to do more to make that part work.


Help me~!!

Thanks.
