SCC 不支持可分页？

Question

我正在使用 Spring Cloud Contract (1.1.0)，但是当我想使用时我完全卡住了 可分页

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

以下示例正在运行，没有可分页

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

而这个正在使用可分页

@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);
}

我的合同在这里。为第一个示例工作，而不是为第二个示例工作

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')
        }
    }
}
]

还有堆栈跟踪：

我该怎么办？我应该修改什么才能使其正常工作？

Answer 1

但是您到底想达到什么目的？您在示例中展示的内容实际上是包含两个元素的单个主体。那是你想要发送的吗？或者你想要第一次调用第一个元素，然后是第二个。如果是这种情况，那么您将使用场景 http://cloud.spring.io/spring-cloud-contract/1.0.x/#_scenarios 进行有状态案例。您需要签订 2 份单独的合同。

另一个问题是您是否真的需要测试分页是否有效。您想测试合同是否有效，并且只发送一次请求（或者我错过了您想要测试的东西？）。

更新：

我认为这与 Spring Data + Rest Assured 有关。请查看这个问题 - Isolated Controller Test can't instantiate Pageable

Answer 2

使用 Pageable 参数，Spring Data Rest 可以识别排序参数：http://docs.spring.io/spring-data/rest/docs/current/reference/html/#paging-and-sorting.sorting

但是在使用 Contract 进行单元测试时，无法创建 Pageable，因为它是一个接口...
