我是 Spring 開發的新手，正在嘗試學習。安裝了 Netbeans 11.1 并克隆了這個git 存儲庫并嘗試讓這個 VideoController 通過。我很驚訝為什么 testAddGetVideo() 測試在組中運行時失敗，但在單獨運行時卻通過。測試套件在這里。糾結了好幾天了。通讀SO和其他帖子。testAddGetVideo 在測試套件中失敗，但個別測試通過（向下滾動查看下文）在堆棧跟蹤中有一個org.springframework.web.HttpMediaTypeNotAcceptableException測試添加獲取視頻（）：@Testpublic void testAddGetVideo() throws Exception {? ? videoSvc.addVideo(video);? ? Collection<Video> stored = videoSvc.getVideoList();? ? assertTrue(stored.contains(video));}它調用的我的 VideoController 方法：/**?* getVideos?*?* @return Collection<Video>?*/@RequestMapping(value = VIDEO_SVC_PATH, method = RequestMethod.GET)public @ResponseBody Collection<Video> getVideos(HttpServletResponse response) {? ? System.out.println("---------------getVideos---------------");? ? System.out.println(videos.size() + " videos");? ? System.out.println("===================");? ? response.setContentType("application/json");? ? response.setStatus(200);? ? return videos.values();}/**?* newVideo?*?* @param v?* @return Video?*/@RequestMapping(value = VIDEO_SVC_PATH, method = RequestMethod.POST)public @ResponseBody Video newVideo(@RequestBody Video v) {? ? System.out.println("---------------newVideo---------------");? ? checkAndSetId(v);? ? String url = getDataUrl(v.getId());? ? v.setDataUrl(url);? ? videos.put(v.getId(), v);? ? System.out.println("video " + v.getId() + " at " + v.getDataUrl());? ? System.out.println("===================");? ? return v;}視頻服務public static final String VIDEO_SVC_PATH = "/video";public static final String VIDEO_DATA_PATH = VIDEO_SVC_PATH + "/{id}/data";/**?* This endpoint in the API returns a list of the videos that have?* been added to the server. The Video objects should be returned as?* JSON.??*??* To manually test this endpoint, run your server and open this URL in a browser:?* http://localhost:8080/video?*??* @return?*/

不知道為什么，但下面的更改修復了它。問題可能出在自動化測試上。
@Test
public void testGetNonExistantVideosData() throws Exception {
long nonExistantId = getInvalidVideoId();
try{
Response r = videoSvc.getData(nonExistantId);
assertEquals(404, r.getStatus());
}catch(RetrofitError e){
assertEquals(404, e.getResponse().getStatus());
}
}
我的方法簽名如下。我將方法更改為當傳入無效 id 作為參數時返回 null，并且僅當傳入有效 id 并且二進制視頻 mpeg 數據成功寫入 HttpServletResponse.Outputstream 時才返回 VideoStatus。
換句話說，做 aresponse.sendError()也需要 a return null;。
@RequestMapping(value = VIDEO_DATA_PATH, method = RequestMethod.POST)
public @ResponseBody VideoStatus uploadVideo(@PathVariable("id") long id, @RequestParam("data") MultipartFile data, HttpServletResponse response) {
VideoStatus status = new VideoStatus(VideoStatus.VideoState.READY);
