spring-data - Spring Boot Rest 搜索 404

Question

我定期注意到 /search似乎不适用于我的 @RepositoryRestResource :

Spring Boot 输出

curl /人

curl http://localhost:8080/persons
{
  "_links" : {
    "self" : {
      "href" : "http://localhost:8080/persons{?page,size,sort}",
      "templated" : true
    }
  },
  "_embedded" : {
    "persons" : [ {
      "firstName" : "Jimmy",
      "lastName" : "Neutron",
      "_links" : {
        "self" : {
          "href" : "http://localhost:8080/persons/2"
        }
      }
    }, {
      "firstName" : "Jimmy",
      "lastName" : "Page",
      "_links" : {
        "self" : {
          "href" : "http://localhost:8080/persons/3"
        }
      }
    }, {
      "firstName" : "Jimmy",
      "lastName" : "Johns",
      "_links" : {
        "self" : {
          "href" : "http://localhost:8080/persons/4"
        }
      }
    } ]
  },
  "page" : {
    "size" : 20,
    "totalElements" : 3,
    "totalPages" : 1,
    "number" : 0
  }

/搜索上的 curl

curl -v http://localhost:8080/persons/search
* Adding handle: conn: 0x7f9903004400
* Adding handle: send: 0
* Adding handle: recv: 0

通常我可以重新启动应用程序，它会随机出现 0 个更改:

curl http://localhost:8080/persons
{
  "_links" : {
    "self" : {
      "href" : "http://localhost:8080/persons{?page,size,sort}",
      "templated" : true
    },
    "search" : {
      "href" : "http://localhost:8080/persons/search"
    }
  },
  "page" : {
    "size" : 20,
    "totalElements" : 0,
    "totalPages" : 0,
    "number" : 0
  }

是否需要 100% 的时间启用搜索功能？

我有同样的问题，并发现导致它。

Spring 仅为您的域类型加载一个存储库以查找搜索资源映射。如果您的域类型有多个存储库，spring 会以某种方式随机选择一个并使用该存储库。如果该方法不包含您的自定义搜索方法，则不会加载。
