Junit mockito 测试Controller层方法有Pageable异常

编程爱好者联盟 2016-11-02

1、问题

在使用MockMVC+Mockito模拟Service层返回的时候,当我们在Controller层中参数方法调用有Pageable对象的时候,我们会发现,我们没办法生成一个Pageable的对象,会报一个Pageable是一个接口的错误。当我们把所有的参数从Pageable接口变成Pageable的实现类PageRequest的时候,所有的方法参数都换成PageRequest,又会出现一个新的错误,且不说PageRequest不能作为参数用于hibernate的分页查询,另一方面,它没有构造方法,也无法初始化。

2、代码

1)controller代码,主要是 

@RequestMapping("/banners")
    public DataMap showBanners(BannerQuery bannerQuery, @PageableDefault(sort = "createdAt", direction = Sort.Direction.DESC) Pageable pageable) {
        Page<Banner> page = bannerService.findPage(bannerQuery, pageable);
        return new DataMap().addAttribute(Constants.STATUS_CODE, StatusCode.SUCCESS.getStatusCode())
                .addAttribute(Constants.DATA, page);
    }

2)测试方法: 

@Test
    public void showBannersWithWhenTest() throws Exception {

        Banner banner = new Banner();
        banner.setBannerUrl("www.baidu.com");
        banner.setActionUrl("hhtp");
        List<Banner> list = new ArrayList<>();
        list.add(banner);
        Page<Banner> page = new PageImpl<Banner>(list);

        when(bannerService.findPage(isA(BannerQuery.class),isA(Pageable.class))).thenReturn(page);     //mock绑定了放回
        //生成一个发送请求的类
        RequestBuilder rb = get("/banners")  //请求的url
                .param("page","0")           //请求的参数
                .param("size","5")
                .contentType(MediaType.APPLICATION_FORM_URLENCODED);

        String responseString = mockMvc.perform(rb)
                .andDo(print())                                     //添加ResultHandler结果处理器,比如调试时打印结果到控制台
               /* .andExpect(jsonPath("$.data.content").isArray())    //判断返回的数据是否是一个数组*/
                .andExpect(status().isOk())                         //判断返回的状态是否为200
                /*.andExpect(jsonPath("$.data.content",hasSize(5)))   //判断返回的json对象的data.content属性的大小是否为5
                //判断返回的data.content中的第一个对象的uid属性是否为所给值
                .andExpect(jsonPath("$.data.content[0].uid",is("81377051ddb6424fa677931ab1bc6496")))
                .andExpect(jsonPath("$.data.content[1].uid",is("8cb7b04fdea846d2ab6006fa1280a8b8")))*/
                .andReturn().getResponse().getContentAsString();



        System.out.println("--------showCategorysTest()返回的json = " + responseString);

    }

3)报错:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.domain.Pageable]: Specified class is an interface

3、解决方法: 

报错的原因:没有Pageable的解析器。

解决的方法:给他设置一个解析器

1)使用匿名内部类

@Before()
    public void setup() {
        MockitoAnnotations.initMocks(this);

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

 2)通过注解的方式注入一个PageableHandlerMethodArgumentResolver 解析器


@InjectMocksprivate PageableHandlerMethodArgumentResolver pageableArgumentResolver;
@Before()
    public void setup() {
        MockitoAnnotations.initMocks(this);

        mockMvc = MockMvcBuilders.standaloneSetup(bannerController).setCustomArgumentResolvers(pageableArgumentResolver)
                .build();
    }
