这是我的国家存储库.java文件
我没有收到错误到底发生了什么，请在下面的代码中建议我到底需要做什么。
这是我的国家服务.java
国家服务.java
在共同的UtlityController中.java我还自动连线了国家服务
错误说 -No qualifying bean found for dependency [in.techchefs.anyspace.common.dao.CountryRepository]
您正在尝试注入一个未注释为依赖项注入的类。您必须使用以下注释标记interface CountryRepository才能自动连线。
@Repository
interface CountryRepository {
//...
}
供参考 - http://zetcode.com/springboot/annotations/
存储库中缺少注释。
package in.techchefs.anyspace.common.dao;
import java.util.List;
import in.techchefs.anyspace.common.dto.PagingInfo;
import in.techchefs.anyspace.common.model.Country;
@Repository
public interface CountryRepository {
Country getByIsoCode(String isoCode);
Country getByCountryCode(String countryCode);
List<Country> getCountryAndCurrencyList(String countryName,Integer pageNum,Integer maxNbPerPage);
List<Country> getCountryAndCurrencyList(String countryName,PagingInfo pagingInfo);
List<Country> getAllCountryList();
}
您还可以使用其他存储库(如 CrudRepository(扩展您的存储库，这些存储库有一些方法来保存一些样板代码。 有关各种存储库的更多信息，您可以参考以下内容：https://www.baeldung.com/spring-data-repositories
您错过了添加@Repository。 Spring @Repository 注解是@Component注解的专用化，因此 Spring 框架通过类路径扫描自动检测Spring 存储库类。
package in.techchefs.anyspace.common.dao;
import java.util.List;
import in.techchefs.anyspace.common.dto.PagingInfo;
import in.techchefs.anyspace.common.model.Country;
@Repository
public interface CountryRepository {
Country getByIsoCode(String isoCode);
Country getByCountryCode(String countryCode);
List<Country> getCountryAndCurrencyList(String countryName,Integer
pageNum,Integer
maxNbPerPage);
List<Country> getCountryAndCurrencyList(String countryName,PagingInfo
pagingInfo);
List<Country> getAllCountryList();
}
countryRepository 应该用@Repository标签进行注释。使用您当前的配置，Spring 不会扫描类并了解它。在启动和接线的那一刻将找不到国家存储库类。
编辑 如果添加@Repository标签没有帮助，那么我认为问题现在可能出在 countryServiceImpl 和 countryService。
尝试用@Service注释国家服务(接口(。由于服务应该只有一个实现，因此无需使用可选参数 @Service("countryService"( 指定名称。Spring 将根据接口的名称自动生成它。
控制器中不需要@Qualifier，因为服务只有一个实现。
