netbeans 8.2でspringブートinitiliazerプロジェクトオプションを使用してWebアプリケーションを構築しようとしています。私はそれを起動するとRUNのプログレスバーは、ディスパッチャサーブレットの初期化が完了した後にハングアップします。 localhost：8080からページを取得しようとするとエラーが返されます。私はそれがディスパッチャサーブレット構成とは何かを持っていると思うが、私はわからないんだけど、誰かが私を助けてくださいだろうか？以下は出力ログです。起動時にTomcatを使用したSpringブートWebアプリケーションの起動が失敗する

である、これは私がブラウザに表示されるエラーが

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
はあなたに
EDITに感謝です私コントローラがアプリケーションコンテキストに含まれるかどうかを調べるために、これをメインクラスに追加しました。 getメソッドが見つからない理由
@SpringBootApplication
public class SeedcalendarApplication implements ApplicationContextAware {
private static ApplicationContext ac;
public static void main(String[] args) {
SpringApplication.run(SeedcalendarApplication.class, args);
System.out.println("---------------"+ac.containsBean("loginScreenController"));
LoginScreenController log = ac.getBean(LoginScreenController.class);
//for (String i : ac.getBeanDefinitionNames()) System.out.println(i);
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.ac = applicationContext;
}
}
これは、アプリケーションのコンテキストでlogincontroller isent存在を意味し、FALSE出力し、これは説明します。
@Bean
public LoginScreenController loginScreenController(){
return new LoginScreenController();
}
が、私は（getBeanを使用しようとすると、私はまだorg.springframework.beans.factory.NoSuchBeanDefinitionExceptionを得る：私は取った次のステップは、そのような両方RootconfigとWebConfigのクラスへのBeanとしてlogincontrollerが含まれました）メソッドをメインクラスに追加しました！なぜ誰が知っていますか？
