Spring 启动 + 视频错误 "video playback aborted due to a network error"

Question

所以我设计了一个应用程序，它有一个 reactjs 前端，从 spring 引导后端提供内容。我有一个提供视频的休息控制器。它在大约 10 分钟内运行良好，然后我在浏览器中得到 "video playback aborted due to a network error"。我在这里做错了什么吗？这应该在另一个线程或异步或其他什么上完成吗？我想这都是由 spring.

完成的

@RestController
@CrossOrigin
public class VideoDirectoryController {
@Autowired
private ConfigManager<LibraryConfig> librariesConf;

/**
 * 
 * @param libraryName
 * @param fileName
 * @return
 */
@GetMapping(value = "/getVideo", produces = "video/mp4")
public byte[] getVideo(@RequestParam(value = "library") String libraryName,
        @RequestParam(value = "fileName") String fileName) {
    Library lib = librariesConf.getConfig().getLibraries().get(libraryName.toLowerCase());
    Video video = lib.getVideoFiles().get(fileName);
    lib.getRecentlyViewed().add(video);
    librariesConf.getConfig().getLibraries().keySet().forEach((libr) -> System.out.println("LIBR: :" + libr));
    try (FileInputStream out = new FileInputStream(lib.getFileDirectory(fileName))) {
        return IOUtils.toByteArray(out);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

正如我所说，这可以正常工作大约 10 分钟。如果我使用 :3000（前端）和直接点击 URL 获取视频 (:8080/getVideo)

感谢任何帮助我以前从未在 Spring Boot 中使用过多媒体。

Answer 1

我建议使用 StreamingResponseBody 或直接写入 HttpServletRequest 的 OutputStream。连同设置响应的内容类型和大小。

@GetMapping(value = "/getVideo", produces = "video/mp4")
public void getVideo(@RequestParam(value = "library") String libraryName,
        @RequestParam(value = "fileName") String fileName, HttpServletResponse response) {
    Library lib = librariesConf.getConfig().getLibraries().get(libraryName.toLowerCase());
    Video video = lib.getVideoFiles().get(fileName);
    lib.getRecentlyViewed().add(video);
    librariesConf.getConfig().getLibraries().keySet().forEach((libr) -> System.out.println("LIBR: :" + libr));

    try (FileInputStream out = new FileInputStream(lib.getFileDirectory(fileName))) {
        return StreamUtils.copy(out, response.getOutputStream());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

或者同样使用 StreamingResponseBody

@GetMapping(value = "/getVideo", produces = "video/mp4")
public StreamingResponseBody getVideo(@RequestParam(value = "library") String libraryName,
        @RequestParam(value = "fileName") String fileName) {
    Library lib = librariesConf.getConfig().getLibraries().get(libraryName.toLowerCase());
    Video video = lib.getVideoFiles().get(fileName);
    lib.getRecentlyViewed().add(video);
    librariesConf.getConfig().getLibraries().keySet().forEach((libr) -> System.out.println("LIBR: :" + libr));
    return new StreamingResponseBody() {
        public void write(OutputStream out2) throws IOException {
            try (FileInputStream out = new FileInputStream(lib.getFileDirectory(fileName))) {
                StreamUtils.copy(out, out2);       
            }
        }
    };
}
