spring statemachine 数据 jpa 示例问题

Question

我正在尝试在此处获取 spring statemachine data jpa sample working and I am unable to. I have created a sample github project。到目前为止，我只添加了必要的依赖项并收到此错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.statemachine.data.StateRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 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) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject (AutowiredAnnotationBeanPostProcessor.java:585) at org.springframework.beans.factory.annotation.InjectionMetadata.inject (InjectionMetadata.java:88) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues (AutowiredAnnotationBeanPostProcessor.java:366) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean (AbstractAutowireCapableBeanFactory.java:1264) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean (AbstractAutowireCapableBeanFactory.java:553) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean (AbstractAutowireCapableBeanFactory.java:483)

Answer 1

也许您已经解决了这个问题，但您缺少 jpa 库。可以添加这些，即使用 spring-boot-starter-data-jpa
