java - 无法实例化[org.springframework.data.domain.Pageable] : Specified class is an interface

Question

当我发送诸如 getUserPlaces?page=0&size=5 之类的请求时 我收到此错误:

Failed to instantiate [org.springframework.data.domain.Pageable]: Specified class is an interface

我的 Controller 是:

@Controller
@EnableSpringDataWebSupport
public class UserController {
...
@RequestMapping(value = "/getUserPlaces", method = RequestMethod.POST)
public @ResponseBody List<PlaceDto> getUserPlaces(@RequestBody RoutePagingDto routeRequest, Pageable pageable) {
    return placeService.placeToPlaceDto(userService.getUserPlaces(pageable));
}

在我的 spring-context.xml 中，我将它们声明为 beans:

<beans:bean class="org.springframework.data.web.SortHandlerMethodArgumentResolver" />

<beans:bean class="org.springframework.data.web.PageableHandlerMethodArgumentResolver" />

我缺少什么？

Answer 1

从 UserController 类中删除 @EnableSpringDataWebSupport 并使用以下代码创建 WebConfig 类

@Configuration
@EnableWebMvc
@EnableSpringDataWebSupport
public class WebConfig extends WebMvcConfigurationSupport {}
