@EnableWebMvc注解报错，求大神解决?报错

使用了servlet3.0和spring 3.2，代码如下

public class Initializer implements WebApplicationInitializer {
	@Override
	public void onStartup(ServletContext container) {
		AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
		appContext.register(MvcConfig.class);
		appContext.refresh();
		container.addListener(new ContextLoaderListener(appContext));
		ServletRegistration.Dynamic dispatcher = container.addServlet(
				"dispatcher", new DispatcherServlet(appContext));
		dispatcher.setLoadOnStartup(1);
		dispatcher.addMapping("*.do");
	}
}

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.web.controller")
public class MvcConfig extends WebMvcConfigurerAdapter {
	@Bean
	public InternalResourceViewResolver configureInternalResourceViewResolver() {
		InternalResourceViewResolver resolver = new InternalResourceViewResolver();
		// resolver.setPrefix("/WEB-INF/views/");
		resolver.setSuffix(".jsp");
		return resolver;
	}
	
}

报错信息如下：
