Java 原因：org.springframework.beans.factory.NoSuchBean定义异常：没有类型为的符合条件的bean

我有一个自己无法处理的问题。（在我看来）我已经尽了一切可能。我真的需要你的帮助，因为我没有任何想法

我有一个错误：

...
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfig': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService': Unsatisfied dependency expressed through field 'userRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'web.repositories.UserRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

几天来，我一直在尝试创建SpringSecurityCRUD应用程序。我很困惑。我无法解决此错误。

您必须启用JpaRepositories配置，将

@EnableJpaRepositories

注释添加到您的配置中

@Configuration
@EnableJpaRepositories("web.repositories")
public class ApplicationConfiguration {

   @Bean  public EntityManagerFactory entityManagerFactory() {
     // put here your favourite entity manager factory
   }
}

希望这有帮助

你能分享你的

@SpringBootApplication

注释类吗？@MichaelKreutz但我不使用sprinboot你需要一个@EnableJpaRepositories在你的spring配置中包含repos的packagename。否则您的回购将不会被spring容器获取。好的。有什么理由反对吗？@MichaelKreutz是的。在这个任务中，我不应该使用Springboot（非常感谢！感谢您的回复。这解决了我的问题。但还有另一个问题：由以下原因引起：org.spring frame.green bean.plant.nosuchbean定义异常：没有名为“entityManagerFactory”的bean不可用由您定义此类实体。特别是关于您对交易和bunc的要求是什么我建议你阅读参考资料
