Spring Data Rest - 在_embedded中包含嵌套资源

问题描述

我正在为购物清单开发一个Spring Boot应用程序。
为此，我使用Spring Data Rest通过REST API导出我的实体。

I'm developing a Spring Boot Application for a shopping list.For this I use Spring Data Rest to export my entities through a REST API.

My Architecture看起来像这样

My Architecture looks like this

我有 ShoppingItem ：

public class ShoppingItem {
@Id
@GeneratedValue
private Long id;

@ManyToOne
@JoinColumn(name = "articleId", nullable = false)
private Article article;

private Integer number;

private boolean bought;

public ShoppingItem(){
    this.article = null;
    this.number = 0;
    this.bought = false;
}

}

此购物项目包含一篇文章是一个导出的资源。

This shopping item contains an Article which is an exported Resource.

文章如下所示：

public class Article {

@Id
@GeneratedValue
private Long id;

@Column(unique = true)
private String name;

private Integer price;
}

当我请求ShoppingItem时，答案如下：

When i request a ShoppingItem the answer looks like this:

{
  id: 94,
  number: 1,
  bought: false,
  _links: {
    self: {
      href: "https://myDomain.tld/api/shoppingItems/94"
    },
    article: {
      href: "https://myDomain.tld/api/shoppingItems/94/article"
    }
  }
}

请求 ShoppingItem 时，是否可以在_embedded中包含 Article 所以回复看起来像这样吗？

Is it possible to include the Article in _embedded when requesting the ShoppingItem so the response looks like this?

{
  id: 94,
  number: 1,
  bought: false,
  _links: {
    self: {
      href: "https://myDomain.tld/api/shoppingItems/94"
    },
    article: {
      href: "https://myDomain.tld/api/shoppingItems/94/article"
    }
  },
  _embedded: {
    article: {
      id: '999',
      name: 'someThing',
      price: '1.99'
    }
  }
}

更新1
使用时接受：application / x-spring-data-verbose + json

回复如下：

{
  id: 94
  number: 1
  bought: false
  links: [2]
    0:  {
      rel: "self"
      href: "https://wg.yannic-klem.de/api/shoppingItems/94"
    }-
    1:  {
      rel: "article"
      href: "https://wg.yannic-klem.de/api/shoppingItems/94/article"
    }-
  -
  content: [0]

}

内容列表始终为空：（

推荐答案

尝试添加此接受发出请求时标题：

Accept: application/x-spring-data-verbose+json

另外，看看详细解释了这一点。
