spring - 在 Spring 3.2 上设置 JUnit 的 session 属性

Question

我在设置测试的 session 属性时遇到问题。我正在使用 MockMvc 来测试对 Controller 的调用。 session 模型有一个成员属性(代表已登录的人)。 SessionModel 对象作为 session 属性添加。我期望将其填充到下面的 formBacking 方法的 ModelMap 参数中，但 ModelMap 始终为空。

Controller 代码在通过 Web 应用程序运行时工作正常，但在 JUnit 中则不然。知道我可能做错了什么吗？

这是我的 JUnit 测试

@Test
  public void testUnitCreatePostSuccess() throws Exception {

    UnitCreateModel expected = new UnitCreateModel();
    expected.reset();
    expected.getUnit().setName("Bob");

    SessionModel sm = new SessionModel();
    sm.setMember(getDefaultMember());

    this.mockMvc.perform(
        post("/units/create")
        .param("unit.name", "Bob")
        .sessionAttr(SessionModel.KEY, sm))
        .andExpect(status().isOk())
        .andExpect(model().attribute("unitCreateModel", expected))
        .andExpect(view().name("tiles.content.unit.create"));

  }

这是有问题的 Controller

@Controller
@SessionAttributes({ SessionModel.KEY, UnitCreateModel.KEY })
@RequestMapping("/units")
public class UnitCreateController extends ABaseController {

  private static final String CREATE = "tiles.content.unit.create";

  @Autowired
  private IUnitMemberService unitMemberService;

  @Autowired
  private IUnitService unitService;

  @ModelAttribute
  public void formBacking(ModelMap model) {

    SessionModel instanceSessionModel = new SessionModel();
    instanceSessionModel.retrieveOrCreate(model);

    UnitCreateModel instanceModel = new UnitCreateModel();
    instanceModel.retrieveOrCreate(model);
  }

  @RequestMapping(value = "/create", method = RequestMethod.GET)
  public String onCreate(
      @ModelAttribute(UnitCreateModel.KEY) UnitCreateModel model, 
      @ModelAttribute(SessionModel.KEY) SessionModel sessionModel) {

    model.reset();

    return CREATE;
  }

  @RequestMapping(value = "/create", method = RequestMethod.POST)
  public String onCreatePost(
      @ModelAttribute(SessionModel.KEY) SessionModel sessionModel,
      @Valid @ModelAttribute(UnitCreateModel.KEY) UnitCreateModel model, 
      BindingResult result) throws ServiceRecoverableException {

    if (result.hasErrors()){
      return CREATE;
    }

    long memberId = sessionModel.getMember().getId();

    long unitId = unitService.create(model.getUnit());
    unitMemberService.addMemberToUnit(memberId, unitId, true);

    return CREATE;
  }

}

为您的测试类添加 @WebAppConfiguration 注释并 Autowiring 以下内容。(WebApplicationContext 和 MockHttpSession )

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration({ "classpath:springDispatcher-servlet.xml" })
public class MySessionControllerTest {
    @Autowired WebApplicationContext wac; 
    @Autowired MockHttpSession session;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void testUnitCreatePostSuccess() throws Exception {
        UnitCreateModel expected = new UnitCreateModel();
        expected.reset();
        expected.getUnit().setName("Bob");

        SessionModel sm = new SessionModel();
        sm.setMember(getDefaultMember());
        session.setAttribute(SessionModel.KEY, sm);
        this.mockMvc.perform(
            post("/units/create")
            .session(session)
            .param("unit.name", "Bob")
            .andExpect(status().isOk())
            .andExpect(model().attribute("unitCreateModel", expected))
            .andExpect(view().name("tiles.content.unit.create"));

  }
}
