@Override
public ApplicationContext loadContext(MergedContextConfiguration mergedConfig) throws Exception {
    final MockServletContext servletContext = new MockServletContext(configuration.webapp(),
            new FileSystemResourceLoader());
    final MockServletConfig servletConfig = new MockServletConfig(servletContext, configuration.name());

    final AnnotationConfigWebApplicationContext webContext = new AnnotationConfigWebApplicationContext();
    servletContext.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, webContext);
    webContext.getEnvironment().setActiveProfiles(mergedConfig.getActiveProfiles());
    webContext.setServletConfig(servletConfig);
    webContext.setConfigLocations(mergedConfig.getLocations());
    webContext.register(mergedConfig.getClasses());

    // Create a DispatcherServlet that uses the previously established
    // WebApplicationContext.
    @SuppressWarnings("serial")
    final DispatcherServlet dispatcherServlet = new DispatcherServlet() {
        @Override//from  ww  w .  j  ava2  s. c  o  m
        protected WebApplicationContext createWebApplicationContext(ApplicationContext parent) {
            return webContext;
        }
    };

    // Add the DispatcherServlet (and anything else you want) to the
    // context.
    // Note: this doesn't happen until refresh is called below.
    webContext.addBeanFactoryPostProcessor(new BeanFactoryPostProcessor() {
        @Override
        public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
            beanFactory.registerResolvableDependency(DispatcherServlet.class, dispatcherServlet);
            // Register any other beans here, including a ViewResolver if
            // you are using JSPs.
        }
    });

    // Have the context notify the servlet every time it is refreshed.
    webContext.addApplicationListener(
            new SourceFilteringListener(webContext, new ApplicationListener<ContextRefreshedEvent>() {
                @Override
                public void onApplicationEvent(ContextRefreshedEvent event) {
                    dispatcherServlet.onApplicationEvent(event);
                }
            }));

    // Prepare the context.
    webContext.refresh();
    webContext.registerShutdownHook();

    // Initialize the servlet.
    dispatcherServlet.setContextConfigLocation("");
    dispatcherServlet.init(servletConfig);

    return webContext;
}
