我无法弄清楚..出于某种原因，Spring Junit 没有将我的 bean 添加到上下文中。求救！！
原因：org.springframework.beans.factory.NoSuchBeanDefinitionException：没有可用的“com.api.demo.store.FileStorage”类型的合格bean：预计至少有1个有资格作为自动装配候选者的bean。依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=com.api.demo.store.FileStorageMemDB)} at org .springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1493) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1104) at org.springframework.beans.factory.support .DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1066) 在 org.springframework.beans。
