Java JBOSS应用程序未启动，错误上下文初始化失败：

我有以下错误：

上下文初始化失败：org.springframework.beans.factory.BeanCreationException:创建名为“contactService”的bean时出错：自动连线依赖项的注入失败；嵌套异常为org.springframework.beans.factory.BeanCreationException:无法自动连线字段：私有uaiContacts.repository.ContactRepository uaiContacts.service.ContactService.ContactRepository；嵌套异常为org.springframework.beans.factory.NoSuchBeanDefinitionException:未找到依赖项类型为[uaiContacts.repository.ContactRepository]的匹配bean：至少需要1个符合此依赖项autowire候选项条件的bean。依赖项注释：{@org.springframework.beans.factory.annotation.Autowiredrequired=true}

这是生成错误的类：

这是存储库：

这应该做什么而不是产生错误？您在这里的目标是什么？您是如何尝试修复它的？您是否在上下文路径中有ContactRepository的实现类？您是否可以在xml中附加存储库配置？我将如何在xml中执行此操作？因为我是新手。。。
