SCC不支持Pageable？
SCC不支持Pageable？
提问于 2017-02-15 13:45:43
我正在使用spring云契约(1.1.0)，但是当我想使用Pageable时，我完全被困住了。
http://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/domain/Pageable.html
下面的示例工作正常，不需要分页。
@GetMapping("/employees")
@Timed
public List<EmployeeDTO> getAllEmployees() {
log.debug("REST request to get all Employees");
List<Employee> employees = employeeRepository.findAll();
return employeeMapper.employeesToEmployeeDTOs(employees);
}这个是使用可分页的
@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);
}我的合同在这里。使用第一个示例，而不是第二个示例。
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')
}
}
}
]以及堆栈跟踪：

但你到底想达到什么目的呢？在这个例子中，您所展示的实际上是包含两个元素的单个主体。这就是你想寄的吗？或者您希望第一个调用第一个元素，然后调用第二个元素。如果是这样的话，那么使用场景scenarios来处理有状态的案例。你需要做两份单独的合同。
另一个问题是，您是否真的需要测试分页是否有效。你想要测试合同是否有效，并且只发送一次请求(或者我丢失了你想测试的东西？)
更新：
我认为这与Spring数据+放心有关。请查看此问题- Isolated Controller Test can't instantiate Pageable

使用Pageable参数，Spring识别排序参数：http://docs.spring.io/spring-data/rest/docs/current/reference/html/#paging-and-sorting.sorting
但是在使用合同的单元测试中，不能创建Pageable，因为它是一个接口.

RestAssuredMockMvc必须注射PageableHandler。控制器接收@PageableDefault。如果不提供PageableHandlerMethodArgumentResolver，则无法找到可访问接口的实现类。
RestAssuredMockMvc.standaloneSetup(MockMvcBuilders.standaloneSetup(configurableProductController).setCustomArgumentResolvers(new PageableHandlerMethodArgumentResolver()));页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
