Question

我有一个单元测试，它使用Spring的MockMvc测试框架来命中REST端点。其余端点要求发送两个字符串路径变量，以及两个java.util.Date对象，这些对象作为 @RequestParameters 传递。当我运行测试时，它失败，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。对于记录，在执行.perform()中列出的结束点之前执行失败，因此此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抛出的例外：

org.springframework.web.bind.MissingServletRequestParameterException：必需的日期参数＆＃39; startDate＆＃39;不存在

我的测试应用程序上下文如下所示：

如何正确地将这些Date对象传递给上述休止端点？

Answer 1

我知道回答已经太晚了，但仅仅是为了将来某人的搜索。

要解决此问题，您可以改为使用get(URL).param：

mvc.perform(MockMvcRequestBuilders.get("/rest/tickets/" + ticketName + "/" + categoryName).param("startDate", new Date())
            .param("endDate", new Date()).with(user(user)));

Answer 2

事实证明，这里出现了一些问题：

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添加到调用中作为查询参数，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。
