使用 PageableDefault 测试休息控制器

Question

我正在尝试测试具有@getmapping一个参数和 PageableDefault的休息服务

   @GetMapping(path = "/api/{serial}/gender")
    public ResponseEntity<?> task(
        @PathVariable(value = "serial") String Serial,
        @PageableDefault(size = 5, value = 0) Pageable pageable) {
    return ResponseEntity.ok(page);
}

带有 mockmvc 的测试套件

@Test
public void testTask() throws Exception {
 String url ="/api/123456789/gender";
    MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get(url))
           .andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
}

我收到以下错误，我无法注入 Pageable 因为它是一个接口，我如何模拟 @pageable 默认值？

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalStateException: No primary or default constructor found for interface org.springframework.data.domain.Pageable

吉列尔莫，

试试这段代码：

mockMvc = MockMvcBuilders.standaloneSetup(controller)
   .setCustomArgumentResolvers(new PageableHandlerMethodArgumentResolver())
   .setViewResolvers(new ViewResolver() {
       @Override
       public View resolveViewName(String viewName, Locale locale) throws Exception {
          return new MappingJackson2JsonView();
      }
   })
   .build();

此致！
