嗨，我目前正在用jUnit测试REST API端点。 我已经成功测试了所有GET方法的端点，现在还剩下POST和PUT端点。
首先，这是我的测试代码。
public void testPostMethod(String url, String content) throws Exception {
mockMvc.perform(post(url).contentType(MediaType.APPLICATION_JSON).content(content)).andDo(print())
.andExpect(status().isOk()).andExpect(content().contentType(contentType));
}
使用此testPostMethod，
@Test
public void edocument_status() throws Exception {
Map<String, String> map = new HashMap<String,String>();
map.put("locale", locale);
map.put("empKey", empKey);
map.put("applKey", applKey);
map.put("apprStatCd", apprStatCd);
map.put("returnReason", returnReason);
String body = map.toString();
testPostMethod("/edocument/status", body);
}
但是以下控制台消息发生错误。

我认为Map-> String部分可能缺少某些内容。 谁能告诉我这是怎么回事？

我用以下修改的代码解决了这个问题。
Student * students = new Student[numStudents];
