Spring Data Couchbase(2.x)文档关系 [英] Spring Data Couchbase (2.x) Document Relation

问题描述

我想问一下关于Spring data benchbase 2.x

I want to ask about spring data couchbase 2.x

我可以在Spring数据沙发基础上引用文档，例如Spring数据mongodb中的@DbRef注释吗?

Can I refer a document in spring data couchbase like @DbRef annotation in spring data mongodb?

推荐答案

我们最初对mongo实施了持久性，并且处于切换到沙发床的模式.这样做，我们发现引用高度依赖于mongo的DBRef来执行关系.应该将其抽象出来并在基础实现之外实现.搜索，索引等也是如此.

we implemented our persistence with mongo initially and are in the mode of switching to couchbase. Doing so, we're finding that referencing is highly relying on DBRef from mongo to perform relationships. This should be abstracted away and implemented outside of the underlying implementation. Same goes for searching, indexing, and the like.

Spring Data有一个@Reference，它确实是由元数据评估的，而@DBRef则将其用于mongodb.

Spring Data has an @Reference which indeed is evaluated by the metadata and @DBRef carries it for mongodb.

示例:

Author.java

Author.java

@Document
public class Author {

    @Field
    private String name;
}

Book.java

Book.java

@Document
public class Book {

    @Field
    private String title;

    @Reference
    private Author author;
}

使用simpledb https://github.com/3pillarlabs/spring-data的@Reference的示例代码-simpledb#reference
