SCC不支持Pageable？

Question

我使用春雲合同（1.1.0），但我完全地被卡住時，我想 可分頁

http://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/domain/Pageable.html

下面的例子正在使用，無需分頁

@GetMapping("/employees") 
@Timed 
public List<EmployeeDTO> getAllEmployees() { 
    log.debug("REST request to get all Employees"); 
    List<Employee> employees = employeeRepository.findAll(); 
    return employeeMapper.employeesToEmployeeDTOs(employees); 
} 

而這一個是使用可分頁的

@GetMapping("/employees") 
@Timed 
public ResponseEntity<List<EmployeeDTO>> getAllEmployees(@ApiParam Pageable pageable) 
    throws URISyntaxException { 
    log.debug("REST request to get a page of Employees"); 
    Page<Employee> page = employeeRepository.findAll(pageable); 
    HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(page, "/api/employees"); 
    return new ResponseEntity<>(employeeMapper.employeesToEmployeeDTOs(page.getContent()), headers, HttpStatus.OK); 
} 

我的合同在這裏。工作的第一個例子，而不是第二

import org.springframework.cloud.contract.spec.Contract 
[ 
Contract.make { 
    name("get all") 
    request { 
     method 'GET' 
     url('/api/employees?sort=id,desc') 

    } 
    response { 
     status 200 
     body([ 
      [id : 1, 
      firstName : value(consumer('test'), producer(regex('[a-zA-Z0-9]{1,255}'))), 
      lastName : value(consumer('test'), producer(regex('[a-zA-Z0-9]{1,255}'))), 
      phoneNumber : value(consumer('test'), producer(regex('[a-zA-Z0-9]{1,255}'))), 
      salary : value(consumer(1000), producer(regex('[0-9]{1,10}'))), 
      commissionPct : value(consumer(1000), producer(regex('[0-9]{1,10}'))) 
      ], 
      [id : 2, 
      firstName : value(consumer('test2'), producer(regex('[a-zA-Z0-9]{1,255}'))), 
      lastName : value(consumer('test2'), producer(regex('[a-zA-Z0-9]{1,255}'))), 
      phoneNumber : value(consumer('test2'), producer(regex('[a-zA-Z0-9]{1,255}'))), 
      salary : value(consumer(2000), producer(regex('[0-9]{1,10}'))), 
      commissionPct : value(consumer(2000), producer(regex('[0-9]{1,10}'))) 
     ] 

     ]) 
     headers { 
      contentType('application/json;charset=UTF-8') 
     } 
    } 
} 
] 

而且堆棧跟蹤：

我該怎麼辦？我應該修改什麼才能使其有效？

Answer 1

但是你究竟想要達到什麼目的？你在這個例子中展現的實際上是一個包含兩個元素的單一主體。那是你想要發送的嗎？或者你想要第一個呼叫的第一個元素，然後第二個。如果是這種情況，那麼你可以通過場景http://cloud.spring.io/spring-cloud-contract/1.0.x/#_scenarios進行一個有狀態的案例。你需要做2個單獨的合同。

另一個問題是，如果您確實需要測試分頁是否有效。你想測試一下合同是否有效，只需要一次發送請求（或者我錯過了你想測試的東西）。

UPDATE：

我認爲這是關係到春天數據+放心。請看看這個問題 - Isolated Controller Test can't instantiate Pageable

Answer 2

隨着可分頁參數，春數據休息識別排序參數：http://docs.spring.io/spring-data/rest/docs/current/reference/html/#paging-and-sorting.sorting

但在單元測試合同，可分頁無法創建，因爲它是一個接口...
