如何使用jhipster映射mapstruct中的对象引用?

假设您使用这样的JDL脚本为博客创建了一个jhipster应用程序,您希望有一个blogdto来显示其中的文章(以及一个blogdto来显示每个文章的评论):

entity Blog {
    creationDate Instant required
    title String minlength(2) maxlength(100) required
}

entity Post {
    creationDate Instant required
    headline String minlength(2) maxlength(100) required
    bodytext String minlength(2) maxlength(1000) required
    image ImageBlob
}

entity Comment {
    creationDate Instant required
    commentText String minlength(2) maxlength(1000) required
}


// RELATIONSHIPS:
relationship OneToMany {
    Blog to Post{blog required}
    Post{comment} to Comment{post(headline) required}
}

// Set pagination options
paginate all with pagination

// DTOs for all
dto * with mapstruct

// Set service options to all except few
service all with serviceClass

// Filtering
filter *

jhipster将用DTO创建您的博客、帖子和评论实体,并假设您不希望在博客中填充帖子或带有评论的帖子,因此您的bloggmapper将如下所示:

@Mapper(componentModel = "spring", uses = {})
public interface BlogMapper extends EntityMapper<BlogDTO, Blog> {

    @Mapping(target = "posts", ignore = true)
    Blog toEntity(BlogDTO blogDTO);


    default Blog fromId(Long id) {
        if (id == null) {
            return null;
        }
        Blog blog = new Blog();
        blog.setId(id);
        return blog;
    }
}

像这样的博客:

public class BlogDTO implements Serializable {

    private Long id;

    @NotNull
    private Instant creationDate;

    @NotNull
    @Size(min = 2, max = 100)
    private String title;
//GETTERS, SETTERS, HASHCODE, EQUALS & TOSTRING

任何人都能帮助修改代码,使blogdto显示文章(postdto显示注释)吗?谢谢

因为我把注释改为包含Postmapper类 @映射器(componentmodel=“spring”,使用postmapper.class)

而@mapping(target=“posts”,ignore=false)为false,但不起作用。API示例(swagger)看起来不错,但postdto为空(即使数据在那里)。
