UnsatisfiedDependencyException：创建名称为'busServiceImpl'

Question

我正在尝试使用春季靴子并使用肥皂服务。我收到称为未满足的依赖项异常的错误。我已经尝试过，但无法解决。

我已经添加了xsd文件，并通过jaxb获得了pojo类。然后，我添加了用于通过spring data jpa连接数据库的实体类。我已经创建了存储库，服务，端点和配置。请任何人都可以帮助我找出解决方案。

我的代码是

BusTicket.xsd

通过使用Wsdl文件，我想在soapui中检查我的应用程序。如果我请求busno，并且需要BusDetailsResponse。那是我的例外结果。
