@Bean 控制器没有被@EnableMVC 接收

Question

我的大部分@Controller 都是通过组件扫描获取的。但是，有一些，例如我在 Spring Social 中使用的那些，被创建为 @Beans。我刚刚从主要 xml 迁移到仅 JavaConfig 并升级到 Spring 4.1.9.

但是，创建为 @Beans 的控制器端点正在创建 404。

有什么想法吗？

package nl.project.webapp.config;

@Order(1)
public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{WebAppConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[]{ServletConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

    [...]
}

package nl.project.webapp.config;

@Configuration
@ComponentScan(basePackages = {"nl.project.webapp"},excludeFilters={
    @ComponentScan.Filter(type=FilterType.ANNOTATION,value=Controller.class),
    @ComponentScan.Filter(type=FilterType.ANNOTATION,value=RestController.class)
})
@Import({AppConfig.class,JPAConfig.class})
@PropertySource("classpath:msa.properties")
public class WebAppConfig {
    [...]
}

package nl.project.webapp.config;

    @ComponentScan.Filter(type=FilterType.ANNOTATION,value=Controller.class),
    @ComponentScan.Filter(type=FilterType.ANNOTATION,value=RestController.class)    
})
public class ServletConfig extends WebMvcConfigurerAdapter{
   [...]    
}

package nl.project.webapp.social.config;

@Configuration
public class SocialConfig{

    @Bean
    public MyConnectController connectController(MessageSource messages, UsorManager userMgr, PhotoManager photoMgr) {

        MyConnectController connectController = new MyConnectController(connectionFactoryLocator, connectionRepository);
        connectController.setConnectInterceptors(Arrays.asList(new ConnectInterceptor<?>[]{
            new TwitterConnectInterceptor(userMgr, photoMgr, messages),
            new FacebookConnectInterceptor(userMgr, photoMgr, messages),
            new LinkedInConnectInterceptor(userMgr, photoMgr, messages),
            new GoogleConnectInterceptor(userMgr, photoMgr, messages),
        }));

        return connectController;
    }

    @Bean 
    public MySignInController signinController(MessageSource messages, UsorManager userMgr, PhotoManager photoMgr){

        MySignInController signinController = new MySignInController(connectionFactoryLocator, usersConnectionRepository, new SimpleSigninAdapter(userMgr));
        signinController.setSignInInterceptors(Arrays.asList(new ProviderSignInInterceptor<?>[]{
            new FacebookSigninInterceptor(userMgr, photoMgr, messages),
            new LinkedInSigninInterceptor(userMgr, photoMgr),
            new GoogleSigninInterceptor(userMgr, photoMgr)
        }));

        return signinController;
    }

}


package nl.project.webapp.social.controller;

@Controller
@RequestMapping("/signin")
public class MySignInController extends ProviderSignInController {

    public MySignInController(
            ConnectionFactoryLocator connectionFactoryLocator,
            UsersConnectionRepository usersConnectionRepository,
            SignInAdapter signInAdapter) {
        super(connectionFactoryLocator, usersConnectionRepository, signInAdapter);
        this.connectionFactoryLocator = connectionFactoryLocator;

    }

问题是由 WebAppConfig 而不是 ServletConfig 导入的 SocialConfig 引起的。尽管文档表明上下文中可用的任何 Controller bean 都将通过使用“@EnableWebMVC”来获取，但尚不清楚这不适用于通过 webapp 上下文加载的 Controller bean。
