[解決済み】Spring Boot。EmbeddedServletContainerFactoryビーンがないため、EmbeddedWebApplicationContextを起動できません。

質問

Springは全くの初心者で、このサイトの公式ガイドをやり始めました。 https://spring.io/guides

このガイドをやりたいのですが https://spring.io/guides/gs/scheduling-tasks/

以下のExceptionが発生します。

アプリケーション・スターター・クラスはこれです。

@ComponentScan
@EnableAutoConfiguration
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(ScheduledTasks.class, args);
    }
}

ご覧の通り、mainメソッドにはコメント行が含まれています。私はすでにチュートリアル、すなわちこのチュートリアルを行っています。 https://spring.io/guides/gs/consuming-rest/ 立ち上がっています。しかし、以下のようなScheduledTasksアプリを実行することができないのです。

@EnableScheduling
public class ScheduledTasks {

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Scheduled(fixedRate = 5000)
    public void reportCurrentTime() {
        System.out.println("The time is now " + dateFormat.format(new Date()));
    }
}

Eclipseを使い、Application.javaのmainをApplicationとして実行しています。 どなたか助けていただけませんか？

どのように解決するのですか？

スケジューリングガイドはWebアプリではないので、おそらくRESTガイドのpom.xmlにカビが生えたようなものが入っているのでは？その指示に忠実に従えば、うまくいくはずです。上に投稿したコードのもう一つの潜在的な問題は、あなたの @EnableAutoConfiguration クラスはコンテキストでは使用されず、メインメソッドとしてのみ使用されます (これはスケジューリングガイドにとっては問題ではないかもしれませんが、おそらく他の多くの人にとっては問題なのでしょう)。
