MongoDB Spring 引导项目中的一对多和多对一关系

Question

请问如何在 mongoDB 中添加关系，因为我才刚刚开始使用它。例如评论id是外键:

 @Document
    class Comment {

        @Id
        private String id;
        private String text;
        private String author;

        // constructors, getters and setters are ommited
    }

    @Document
    class Article {
        @Id
        private String id;
        @DBRef(lazy = true)
        @CascadeSave
        private List<Comment> comments;
        private String title;
        private String text;

        // constructors, getters and setters are ommited
    }

Answer 1

JPA 注解@OneToMany 和@ManyToMany 等价于@DBRef
