Question

我有一个Java Spring启动项目，我正在创建一个post请求。代码如下所示：

主：

@SpringBootApplication
public class Main

{

public static void main(String[] args)
{

    SpringApplication.run(Main.class,args);

}

}

Java bean：

@Data
@Entity
public class Image {

private @Id @GeneratedValue Long id;
private String imageNo;
private String name;

private Image(){}

public Image(String imageNo, String name){
    this.imageNo = imageNo;
    this.name = name;

 }

}

存储库：

public interface ImageRepository extends CrudRepository<Image, Long> {

 }

DatabaseLoader：

@Component
public class DatabaseLoader implements CommandLineRunner {

private final ImageRepository repository;

@Autowired
public DatabaseLoader(ImageRepository repository) {
    this.repository = repository;
}

@Override
public void run(String... strings) throws Exception {
    this.repository.save(new Image("1", "Baggins"));
}
}

但是当我运行项目时，我收到以下错误：

    Description:

Parameter 0 of constructor in com.face.DatabaseLoader required a bean of type 'com.face.ImageRepository' that could not be found.

Action:

Consider defining a bean of type 'com.face.ImageRepository' in your configuration.

感谢任何帮助！非常感谢，

您的spring容器不会扫描Image存储库，因为它没有注释。要解决此问题，您应该使用@Repository注释注释ImageRepository，如下所示 -

@Repository
public interface ImageRepository extends CrudRepository<Image, Long> {

 }

考虑在配置中定义'com.face.ImageRepository'类型的bean？
