このコードを実行しようとすると、
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
java.lang.NullPointerException
at java.util.concurrent.ConcurrentHashMap.get(Unknown Source)
atorg.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.determineCandidateConstructors(AutowiredAnnotationBeanPostProcessor.java:186)
アプリケーションを実行しようとすると404が発生します。私が間違っていることについて何か考えはありますか?
