我有存储库“ ClientRepository”：

public interface ClientRepository extends PagingAndSortingRepository<Client, Long> {
}

当我请求http：// localhost：8080 / clients /
1时，服务器响应

{
  "algorithmId" : 1,
  "lastNameTxt" : "***",
  "firstNameTxt" : "**",
  "middleNameTxt" : "**",
  "_links" : {
    "self" : {
      "href" : "http://localhost:8080/clients/1121495168"
    },
    "client" : {
      "href" : "http://localhost:8080/clients/1121495168"
    }
  }
}

响应具有预期的链接。

当我在另一个控制器中调用存储库继承的方法findOne时

@RestController
public class SearchRestController {

    @Autowired
        public SearchRestController(ClientRepository clientRepository) {
            this.clientRepository = clientRepository;
    }

    @RequestMapping(value = "/search", method = RequestMethod.GET)
        Client readAgreement(@RequestParam(value = "query") String query,
                @RequestParam(value = "category") String category) {
    return clientRepository.findOne(Long.parseLong(query));
    }
}

它回应

{
      "algorithmId" : 1,
      "lastNameTxt" : "***",
      "firstNameTxt" : "**",
      "middleNameTxt" : "**"
}

为什么在第二种情况下响应不包含链接？如何使Spring添加他们的响应？
