java如何修复组织。springframework。豆。工厂BeanCreationException

3 周 Questions & Answers 1258

我有一个JavaSpringMVCWeb应用程序。现在我有了以下控制器类：

@Controller
@RequestMapping("module/car")
public class CrentalCarController 
{
@Autowired
@Qualifier("restClientService")
private RESTClientService  restClientService;

//the remaining codes
}

我有另一个界面，如下所示：

public interface RESTClientService
{
}

以及实现上述接口的类。该接口位于另一个项目中，该项目作为依赖项添加到包含我在开头提到的控制器的项目中。一旦我添加了

@Autowired
    @Qualifier("restClientService")
    private RESTClientService  restClientService;

对于我的控制器，控制台中出现以下错误：

 ERROR o.s.web.context.ContextLoader - Context initialization failed

我无法弄清确切的问题，我不确定我在这里是否做错了什么

有 Java 编程相关的问题?
