Question

我在项目中使用Spring Data REST和Spring HATEOAS。我正在从Angular客户端使用REST API。

我的应用程序中有非常复杂的模型，而且一直想知道我是否以正确的方式使用HATEOAS。

这是一个联系资源：

是否有太多像我这样的链接？如果我不发送邮件，我应该如何对客户说如何导航？这只是一种资源，但是请考虑一下，当我要请求分页结果时...响应大小很大（即使我使用的是Spring投影），并且主要是由于链接造成的！
客户有一个关系store（http://localhost:8082/api/v1/contacts/1/store）。我想在POST呼叫中使用此链接。实际上，假设我要复制当前客户，我想避免调用http://localhost:8082/api/v1/contacts/1/store以获得商店的自我链接，而宁愿在链接中传递链接http://localhost:8082/api/v1/contacts/1/store新客户的主体（这样可以避免额外的HTTP调用）：

{  
      "billingCountry": "IT",  
      "firstName": "First name",
      "lastName": "Last name",
      "gender": "MALE", 
      "personType": "NATURAL_PERSON", 
      "shippingCountry": "IT",
      "store": "http://localhost:8082/api/v1/contacts/1/store",
      "type": "CUSTOMER"
 }

这似乎是不可能的，但我必须创建一个自定义解串器。我搞错了，在POST中使用嵌套链接来保存资源不是一个好习惯吗？

使用Spring HATEOAS解决POST中的嵌套链接
