Cron式は6つのフィールド（ "$ {cron.expression}の1つが見つかりました）が部分的に修正されていますが、AnnotationConfigApplicationContextに問題があります"

Question

cron式をパラメータ化し、 "名前が 'beanScheduleCronExample'のBeanを作成中にエラーが発生しました：Beanの初期化に失敗しました。そして

クーロン発現「（「$ {cron.expression}」1見出さ）6つのフィールドで構成しなければならない私はpost

次実測値：遭遇無効@Scheduled方法「cronジョブ」：ネストされた例外は、java.lang.IllegalStateExceptionであります

私は表現が、私は

を持っている場合にのみ、読まれているAnnotationConfigApplicationContextコンテキストは=新しいAnnotationConfigApplicationContext（ SpringScheduleCronExample.class）のcronことを利用し、

は私の主な方法で定義する私が午前問題があり、。したい メインメソッドなしでサーバー上でこれを実行すると、誰もこれで私を助けてください。ここで

はあり cron.expression = */5 * * * *

私のアプリケーションのプロパティのように見える私のapplicationContext.xmlをですか？ここで

Answer 1

は、私はそれが

アプリケーションのcontext.xml

     return properties; 
    }

MyApplicationContext.java

パッケージcom.hemalを動作するようになった方法です。春;

import javax.servlet.ServletException;

    public void onStartup(ServletContext servletContext) throws ServletException { 
     AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); 
     rootContext.register(MyApplicationConfig.class); 


     servletContext.addListener(new ContextLoaderListener(rootContext)); 
    } 
}
