标签： spring-boot

我正在使用Spring Cloud做一些练习，尝试启动时我的应用程序给出了一个错误：

申请无法开始

说明：

Parameter 2 of constructor in com.innovation.validadorcpf.core.service.impl.CPFServiceImpl required a bean of type 'com.innovation.validadorcpf.core.repository.CPFRepository' that could not be found.

操作：

考虑在您的配置中定义类型为com.innovation.validadorcpf.core.repository.CPFRepository的bean。

以退出代码1完成的过程

这是我的服务等级，我找不到错误，有人可以帮助我吗？

在CPFServiceImpl类中进行自动接线，如下所示：

@Autowired
private CPFRepository cpfRepository;

对构造函数中定义的所有变量都执行相同的操作，除非在其他地方未设置该变量，否则不需要此构造函数：

 @Autowired
    public CPFServiceImpl(Message mensagem, CPFValidator cpfValidator, CPFRepository cpfRepository, StringToCPFConverter cpfConverter) {
        this.mensagem = mensagem;
        this.cpfValidator = cpfValidator;
        this.cpfRepository = cpfRepository;
        this.cpfConverter = cpfConverter;
    }

并定义以下类（可选）：

@Slf4j
@Service("cPFService")
public class CPFServiceImpl implements CPFService {

是的，在我的组件扫描和MongoConfiguration类中，我指定了其他程序包
