无法自动连接mongodb存储库spring boot

Question

我在Spring Boot上还是新手，我在mongoDB数据库中使用Spring-Boot添加了一个名为文章的文档，我想在该文章中添加注释。但是Spring-boot不能在我的应用程序中自动连接我的存储库。

下面是我的Repository类，它实现了ArticleRepositoryCustom接口，该接口包含一个OuterComment方法。

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Springboot应用程序课程

@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时，我得到以下异常

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'example2MongoDbApplication': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private demo.ArticleRepository demo.Example2MongoDbApplication.repository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'articleRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property ajouterComment found for type void!

这是我的课堂文章

@Document
public class Article {
@Id
private ObjectId id;

private UUID authorId;
private String author;
private Date date;
private String title;
private byte text;
public List<Comment> comments;



public List<Comment> getComments() {
    return comments;
}
public void setComments(List<Comment> comments) {
    this.comments = comments;
}
public ObjectId getId() {
    return id;
}
public void setId(ObjectId id) {
    this.id = id;
}
public UUID getAuthorId() {
    return authorId;
}
public void setAuthorId(UUID authorId) {
    this.authorId = authorId;
}
public String getAuthor() {
    return author;
}
public void setAuthor(String author) {
    this.author = author;
}
public Date getDate() {
    return date;
}
public void setDate(Date date) {
    this.date = date;
}
public String getTitle() {
    return title;
}
public void setTitle(String title) {
    this.title = title;
}
public byte getText() {
    return text;
}
public void setText(byte text) {
    this.text = text;
}
public Article(UUID authorId, String author, Date date, String title) {
    super();
    this.authorId = authorId;
    this.author = author;
    this.date = date;
    this.title = title;
}

}

谁能帮帮我吗？

我非常确定，根据本文档，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选中，因为它以Imp而不是Impl结尾。以下是相关文本：

如果使用名称空间配置，则存储库基础结构会尝试通过扫描我们在其中找到存储库的包下面的类来自动检测自定义实现。这些类需要遵循命名约定，将名称空间元素的属性repository impl后缀附加到找到的存储库接口名称。此后缀默认为Impl。

他们确实提到了一种配置后缀的XML方法，如果您想这样做的话。可能还有Java配置或注释方法，但我现在还不知道。
