考虑在您的配置中定义一个类型为'com.face.ImageRepository'的bean？

Question

我有一个Java Spring Boot项目，我正在其中创建一个post请求。代码如下所示：

主要：

@SpringBootApplication
public class Main

{

public static void main(String[] args)
{

    SpringApplication.run(Main.class,args);

}

}

@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;

 }

}

public interface ImageRepository extends CrudRepository<Image, Long> {

 }

@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，当我运行该项目时，我会得到以下错误：

    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.

感谢您对此的任何帮助！非常感谢，

您的spring容器不会扫描图像存储库，因为它没有注释。要解决这个问题，您应该使用@repository注释来注释ImageRepository如下所示-

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

 }
