java - 为什么这个 MockMvc 测试失败了？

Question

这是我拥有的控制器：

@Controller
@EnableWebMvc
@RequestMapping(value = "/spittles")
public class SpittleController {

    SpittleRepository spittleRepository;

    @RequestMapping(method = RequestMethod.GET)
    public String getSpittles(Model model) {
        model.addAttribute(spittleRepository.findSpittles(10, 10));
        return "spittles";
    }

    @Autowired
    public void setSpittleRepository(SpittleRepository spittleRepository) {
        this.spittleRepository = spittleRepository;
    }

}

和我的观点（唾沫）：

<c:forEach items="${spittleList}" var="spittle">
    ${spittle.message}
</c:forEach>

效果很好..

但是，此测试失败：

    SpittleController spittleController = new SpittleController();
    spittleController.setSpittleRepository(mockRepository);

    MockMvc mockMvc = MockMvcBuilders.standaloneSetup(spittleController)
            .setSingleView(new InternalResourceView("/WEB-INF/views/spittles.jsp")).build();

    mockMvc.perform(get("/spittles"))
            .andExpect(view().name("spittles"))
            .andExpect(model().attributeExists("spittleList"));

留言：

 java.lang.AssertionError: Model attribute 'spittleList' does not exist

但是在jsp中，看起来模型有属性spittleList，我错过了什么？

Answer 1

嗨，您可以借助 expect 来模拟您的服务，如下所示：

期望（spittleRepository.findSpittles(10, 10)).andReturn（预期输出）

Answer 2

指定名称后，问题是否仍然存在？

model.addAttribute("spittleList", spittleRepository.findSpittles(10, 10));
