无法自动装配 mongodb 存储库 spring-boot
Could not autowire mongodb repository spring-boot
我还是 Spring Boot 的新手，我使用 Spring-Boot 在 mongodb 数据库中添加了一个名为 Article 的文档，我想在该文章中添加评论。但是 Spring-boot 无法在我的应用程序中自动装配我的存储库。
这是我的存储库 class，它实现了包含 ajouterComment 方法的 ArticleRepositoryCustom 接口。
public class ArticleRepositoryImp implements ArticleRepositoryCustom {
@Autowired
private MongoTemplate mongoTemplate;
@Override
public void ajouterComment(String auth,String commentAuth, String text, Date date) {
Comment comment=new Comment("comentAuth", "auth", date);
mongoTemplate.save(comment);
Criteria criteria = Criteria.where("author").is(auth);
mongoTemplate.upsert(Query.query(criteria), new Update().push("comments",comment), Article.class);
}
}
文章库
public interface ArticleRepository extends MongoRepository<Article, ObjectId>,ArticleRepositoryCustom {
public Article findByAuthor(String author);
}
这是我的 SpringBootApplication class
@SpringBootApplication
public class Example2MongoDbApplication implements CommandLineRunner {
@Autowired
private ArticleRepository repository;
public static void main(String[] args) {
SpringApplication.run(Example2MongoDbApplication.class, args);
}
@Override
public void run(String... arg0) throws Exception {
repository.save(new Article(UUID.randomUUID(),"Ettaibi",new Date(),"LKITAB2"));
System.out.println(repository.findByAuthor("med"));
repository.ajouterComment("Med", "Said", "Hello Med", new Date());
}
当我 运行 我的应用程序出现以下异常时

有人可以帮我吗？
我很确定，基于 this documentation，特别是 3.3.1 中的配置部分，您的自定义存储库似乎没有被拾取，因为它以 Imp 而不是 Impl 结尾。以下是相关文字：
If you use namespace configuration, the repository infrastructure tries to autodetect custom implementations by scanning for classes below the package we found a repository in. These classes need to follow the naming convention of appending the namespace element's attribute repository-impl-postfix to the found repository interface name. This postfix defaults to Impl.
他们确实提到了一种 XML 配置后缀的方法，如果您想这样做的话。可能还有 Java 配置或注释方法，但我不知道。
