Answer 1

堆栈跟踪表明没有cacheManager。您需要告诉spring通过将其添加到spring xml配置来初始化cacheManager。

<cache:annotation-driven/>

有关详细信息，请参阅https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/cache/annotation/EnableCaching.html。

org.springframework.beans.factory.BeanCreationException：创建名为＆＃39; org.springframework.cache.interceptor.CacheInterceptor＃0＆＃39;的bean时出错。
