java - 如何通过 Spring MockMvc 将日期对象作为请求参数传递

Question

我有一个单元测试，它使用 Spring 的 MockMvc 测试框架来访问 REST 端点。其余端点要求发送两个字符串路径变量，以及两个作为 @RequestParameters 传递的 java.util.Date 对象。当我运行测试时，它失败了，因为 Date 对象不存在，或者无法从字符串 JSON 表示序列化为 Date 对象。根据记录，在到达 .perform() 中列出的终点之前执行失败，因此该问题不是来自正在测试的代码。它来自测试。

这是我的测试:

    @Test
    public void testGetHitsForCell() {
    String categoryName = "categoryName";

    try {

        String startDateJson = gson.toJson(new Date());
        String endDateJson = gson.toJson(new Date());
        ResultActions ra = mvc.perform(MockMvcRequestBuilders.get("/rest/tickets/" + ticketName + "/" + categoryName).requestAttr("startDate", new Date())
                .requestAttr("endDate", new Date()).with(user(user)));
        MvcResult aResult = ra.andReturn();
        MockHttpServletResponse response = aResult.getResponse();

        assertTrue(response.getContentType().equals("application/json;charset=UTF-8"));
        assertTrue(gson.fromJson(response.getContentAsString(), PaginatedResults.class) instanceof PaginatedResults);
    } catch (Exception e) {
        e.printStackTrace();
        fail(e.getMessage());
    }

端点如下所示:

/rest/ticket/{ticketName}/{categoryName}?startDate=2015-07-21T14%3A26%3A51.972-0400&endDate=2015-08-04T14%3A26%3A51.972-0400

这是 MockMvc 抛出的异常:

org.springframework.web.bind.MissingServletRequestParameterException: Required Date parameter 'startDate' is not present

我的测试应用程序上下文如下所示:

如何才能正确地将这些 Date 对象传递到上述休息端点？

Answer 1

事实证明，这里有一些问题:

我不需要对日期对象使用 .requestAttr() 调用。我只是将日期的字符串表示形式作为查询参数添加到调用中，如下所示:

private String end = "2015-12-31T23:59:59.999Z";
private String start = "2012-01-01T00:00:00.000Z";

ResultActions ra = mvc.perform(MockMvcRequestBuilders.get("/rest/hits/" + modelId + "/0" + "?startDate=" + start + "&endDate=" + end).with(user(user)));

此外，传入 Date 对象会导致问题，因为它们的字符串表示格式错误。菜鸟错误。
