[英]How to pass date objects as request parameters through Spring MockMvc
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,以及作为@RequestParameters传递的两个java.util.Date
对象。 当我运行测试时,它失败了,因为 Date 对象要么不存在,要么无法从字符串 JSON 表示序列化为 Date 对象。 作为记录,在到达.perform()
列出的终点之前执行失败,所以这个问题不是来自被测试的代码。 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:所需的日期参数“startDate”不存在
我的测试应用程序上下文如下所示:

我该怎么做才能将这些 Date 对象正确传递给上述 rest 端点?
我知道现在回答还为时已晚,但是只是为了将来某人的搜索。
为了解决此问题,您可以使用get(URL).param
代替:
mvc.perform(MockMvcRequestBuilders.get("/rest/tickets/" + ticketName + "/" + categoryName).param("startDate", new Date())
.param("endDate", new Date()).with(user(user)));
事实证明,这里有几处错误:
我不需要为日期对象使用.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了调用中,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)));
另外,传入Date对象也会引起问题,因为它们的字符串表示形式格式错误。 新秀错误。
似乎 MockMVC 是愚蠢的。 这不起作用
this.mockMvc.perform(get()
.queryParam("startDate","2011-01-01")
.queryParam("endDate", "2000-11-31")
您必须直接在 URL 中硬编码日期,如下所示:
MockHttpServletRequestBuilder mockHttpServletRequestBuilder = get(CONFIRMATION_API_GET+"?startDate=2019-09-12&endDate=2019-10-13");
