Issue with @ComponentScan, filters since migrating to javaconfig

Question

I am trying to migrate to javaConfig using the following configuration:

WebMvcConfig:

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.bignibou" }, useDefaultFilters = false, 
        includeFilters = {  @Filter(type = FilterType.ANNOTATION, value = Controller.class),
                            @Filter(type = FilterType.ANNOTATION, value = ControllerAdvice.class) })
public class WebMvcConfig extends WebMvcConfigurationSupport {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(converter());
        addDefaultHttpMessageConverters(converters);
    }

    @Override
    protected void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
        argumentResolvers.add(currentMemberHandlerMethodArgumentResolver());
        super.addArgumentResolvers(argumentResolvers);
    }

    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/", "classpath:/META-INF/web-resources/");
        super.addResourceHandlers(registry);
    }

    @Override
    protected void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/cgv").setViewName("conditions/cgv");
        super.addViewControllers(registry);
    }

    @Bean
    public ConversionService conversionService() {
        return new ApplicationConversionServiceFactoryBean().getObject();
    }

    @Bean
    public MappingJacksonHttpMessageConverter converter() {
        MappingJacksonHttpMessageConverter converter = new MappingJacksonHttpMessageConverter();
        converter.setObjectMapper(objectMapper());
        return converter;
    }

    @Bean
    public CustomJacksonObjectMapper objectMapper() {
        return new CustomJacksonObjectMapper();
    }

    @Bean
    public CurrentMemberHandlerMethodArgumentResolver currentMemberHandlerMethodArgumentResolver() {
        return new CurrentMemberHandlerMethodArgumentResolver();
    }

    @Bean
    public FixedLocaleResolver fixedLocaleResolver() {
        FixedLocaleResolver fixedLocaleResolver = new FixedLocaleResolver();
        fixedLocaleResolver.setDefaultLocale(Locale.FRENCH);
        return fixedLocaleResolver;

    }

    @Bean
    public ThymeleafTilesConfigurer tilesConfigurer() {
        ThymeleafTilesConfigurer tilesConfigurer = new ThymeleafTilesConfigurer();
        tilesConfigurer.setDefinitions(new String[] { "/WEB-INF/tiles-defs.xml", "/WEB-INF/web-templates/**/views.xml" });
        return tilesConfigurer;
    }

}

Main config:

@Configuration
@EnableSpringConfigured
@ComponentScan(basePackages = "com.bignibou", 
excludeFilters = {  @Filter(type = FilterType.CUSTOM, value = RooRegexFilter.class),
                    @Filter(type = FilterType.ANNOTATION, value = Controller.class) })
public class MiscellaneousConfiguration {

    @Bean
    public ResourceBundleMessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasenames("META-INF/i18n/application", "META-INF/i18n/messages", "META-INF/i18n/mail-templates", "META-INF/i18n/validation-messages");
        return messageSource;
    }

    @Bean
    public PropertyPlaceholderConfigurer properties() throws IOException {
        PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
        ppc.setLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:META-INF/i18n/*.properties"));
        ppc.setIgnoreUnresolvablePlaceholders(true);
        return ppc;
    }

    @Bean
    public LocalValidatorFactoryBean localValidatorFactoryBean() {
        LocalValidatorFactoryBean localValidatorFactoryBean = new LocalValidatorFactoryBean();
        return localValidatorFactoryBean;
    }
}

And finally my custom regex filter:

public class RooRegexFilter extends RegexPatternTypeFilter {

    public RooRegexFilter() {
        super(Pattern.compile(".*_Roo_.*"));
    }

}

I get errors such as BeanCreationException and NoSuchBeanDefinitionException as follows:

I suspect something is wrong with my @ComponentScan configuration. Can anyone please help?

edit 1: here is my web.xml-equivalent:

public class WebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        XmlWebApplicationContext rootContext = new XmlWebApplicationContext();
        rootContext.setConfigLocations(new String[] { "classpath*:META-INF/spring/applicationContext*.xml" });

        servletContext.addListener(new ContextLoaderListener(rootContext));
        servletContext.addListener(RequestContextListener.class);
        servletContext.addListener(HttpSessionEventPublisher.class);

        servletContext.setInitParameter("defaultHtmlEscape", "true");

        FilterRegistration.Dynamic fr;
        fr = servletContext.addFilter("hiddenHttpMethodFilter", new HiddenHttpMethodFilter());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.addMappingForUrlPatterns(null, true, "/*");

        fr = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.setInitParameter("encoding", "UTF-8");
        fr.setInitParameter("forceEncoding", "true");
        fr.addMappingForUrlPatterns(null, true, "/*");

        fr = servletContext.addFilter("Spring OpenEntityManagerInViewFilter", new OpenEntityManagerInViewFilter());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.addMappingForUrlPatterns(null, true, "/*");

        fr = servletContext.addFilter("springSecurityFilterChain", new org.springframework.web.filter.DelegatingFilterProxy());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.addMappingForUrlPatterns(null, true, "/*");

        AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
        mvcContext.register(WebMvcConfig.class);

        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("bignibou", new DispatcherServlet(mvcContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");


    }
}

The best resource for Java Configuration is the Spring documentation.

It doesn't seem like you are registering your MiscellaneousConfiguration class anywhere. Change this bit

AnnotationConfigApplicationContext rootContext = new AnnotationConfigApplicationContext(MiscellaneousConfiguration.class);
servletContext.addListener(new ContextLoaderListener(rootContext));

I don't know what your XML config was scanning for but apparently it wasn't adding a SearchEngineService bean to the context. Since there is no SearchEngineService bean in the context to autowire into the SearchEngineController bean, context initialization will fail.

---

Note that only your servlet (@WebMvc) config should scan for @Controller. Make your @ComponentScan basePackages more specific so that bean definitions for the same class don't overwrite each other.

---

Also, you will want to make this @Bean method static

@Bean
public static PropertyPlaceholderConfigurer properties() throws IOException {
    PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
    ppc.setLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:META-INF/i18n/*.properties"));
    ppc.setIgnoreUnresolvablePlaceholders(true);
    return ppc;
}

PropertyPlaceholderConfigurer is a BeanFactoryPostProcessor. You can read about why you have to do this in the @Bean javadoc.
