java - 我收到 BeanFactory 错误 : NoSuchBeanDefinitionException and I can't figure out how to solve it

Question

我接到的任务是开发现有的 AngularJS SPA(应用程序 B)。此应用程序使用另一个应用程序(应用程序 B)中的代码从数据库获取信息。两个都;应用程序 A 和应用程序 B 使用相同的数据库。目标是修改应用程序 B 以从不同的数据库获取客户、位置和 jetty 。我的目标是仍然使用应用程序 A 使用的一些相同代码，并为应用程序 B 创建新代码，然后访问新数据库以获取信息。

当我尝试启动应用程序 (Eclipse Oxigen) 时，BeanFactory 抛出异常。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'contextServiceImpl': Unsatisfied dependency expressed through field 'customersRepo'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.csoln.lv.data.cld.dao.CustomersRepo' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

我怀疑 Spring Context 中没有定义该 bean，但我不知道如何定义它。我已经尝试过其他帖子中的建议，但没有任何效果。接下来我将发布代码和相关文件...

请记住，我对 Spring、REStful 服务等还很陌生。我希望你能帮助我解决这个错误。预先感谢您。
