尝试使用 dynamodb 和 graphql 运行我的 Spring Boot 应用程序时，我不断收到此 @bean 错误

Question

这是我得到的错误：

Description:
Field andiRepository in com.service.datafetcher.AllAndisDataFetcher required a bean of type 'com.repositories.AndiRepository' that could not be found.
The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:
Consider defining a bean of type 'com.repositories.AndiRepository' in your configuration.

这是需要 bean 的数据获取器文件：

import com.models.Andi;
import com.repositories.AndiRepository;
import graphql.schema.DataFetcher;
import graphql.schema.DataFetchingEnvironment;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.List;
@Component
public class AllAndisDataFetcher implements DataFetcher<List<Andi>> {
    @Autowired
    AndiRepository andiRepository;
    @Override
    public List<Andi> get(DataFetchingEnvironment dataFetchingEnvironment) throws Exception {
        return andiRepository.findAll();
    }
}

这是驻留在“com”中的主要方法。

package com;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
@SpringBootApplication
@ComponentScan("com.repositories")//to scan repository files
@EntityScan("com.models")
@EnableJpaRepositories("com.repositories.AndiRepository")
public class DynamoDBApplication {
   public static void main(String[] args) {
      SpringApplication.run(DynamoDBApplication.class, args);
   }
}

模型、存储库、服务、包都在主 com 包中。

这是存储库文件：

package com.repositories;

import com.andiskillsmaxmodels.Andi;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface AndiRepository extends CrudRepository<Andi, Integer> {
}

谢谢

更正您的软件包名称。他们到处都是。您似乎从不同的包中导入了类。确保 AndiRepository 在 com.repositories 包中。和Andi 类在你的com.models 包中。纠正这些错误后，请执行以下操作。

删除@ComponentScan("com.repositories")。你不需要这个，因为@SpringBootApplication自动为你做。

并将@SpringBootApplication 替换为@SpringBootApplication(scanBasePackages = "com")
