根资源中缺少一些存储库

Question

我正在学习Restbucks的源代码。我无法找出为什么来自根资源的响应没有得到 org.springsource.restbucks.payment.PaymentRepository 和 org.springsource.restbucks.payment的关系.CreditCardRepository

    {
      "_links": {
        "restbucks:orders": {
          "href": "http://localhost:8080/orders{?page,size,sort,projection}",
          "templated": true
        },
        "restbucks:engine": {
          "href": "http://localhost:8080/engine"
        },
        "restbucks:pages": {
          "href": "http://localhost:8080/pages"
        },
        "curies": [
          {
            "href": "http://localhost:8080/rels/{rel}",
            "name": "restbucks",
            "templated": true
          }
        ]
      }
    }

你能告诉我它是如何运作的吗？
