直播意外结束

问题描述 投票：0回答：3

我不断收到 MalformedStreamException
我正在使用 Java 8 运行 tomcat 9
客户端正在发送分段文件上传（图片和图片名称）
这是函数签名：

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
 @RequestMapping(value = "/fileupload", headers=("content-type=multipart/*"), method = RequestMethod.POST)
public ResponseEntity<String> handleFileUpload( 
        @RequestParam("file") MultipartFile file,
        @RequestParam("pictureId") String pictureId

这是Spring Dispatcher-servlet.xml中的multipartResolver配置

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- max upload size in bytes -->
<property name="maxUploadSize" value="20971520" /> <!-- 20MB -->

<!-- max size of file in memory (in bytes) -->
<property name="maxInMemorySize" value="1048576" /> <!-- 1MB -->

提交多部分的代码正在使用android volley:

       SimpleMultiPartRequest multiPartRequest = new SimpleMultiPartRequest(
            Request.Method.POST,
            Contents.API_SUBMIT_PICTURE,
            new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d("logEntry", "API_SUBMIT_PICTURE: " + response);
                    }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.e("logEntry", "API_SUBMIT_PICTURE: onErrorResponse");
                    submission.failedCount ++;
                    submission.errorDetail = "API_SUBMIT_PICTURE: onErrorResponse";
                }
            }
        );

        multiPartRequest.addFile("file", submissionFile.fileLocation);
        multiPartRequest.addStringParam("pictureId", submissionFile.pictureId);

        volleyHelper.add(multiPartRequest);

这是我迄今为止尝试过的：
我将公共文件上传升级到1.3.3
将java升级到1.8
tomcat升级到9了
一些帖子建议在 tomcat 中设置 maxSowllowSize - 所以我将其设置为 -1 没有帮助...
网络连接良好（在 WiFi 和互联网上用小文件进行测试）
提交代码

我遇到了类似的问题，一些较大的请求或文件上传导致“流意外结束”错误。

事实证明这是由于 Tomcat 9.0.31 造成的，升级它解决了这个问题。 这篇文章更详细地解释了它。

编辑：如果您使用的是使用 Tomcat 9.0.31 的 Spring 或 Spring Boot 版本，请尝试升级到使用较新 Tomcat 版本的版本。

好吧，经过这么多搜索，我能够使用以下代码修复它。

List<String> list = new ArrayList<>();
try (Scanner scanner = new Scanner(new File(fileNameWithPath))) {
  StringBuilder builder = new StringBuilder();
  while (scanner.hasNextLine()) {
    String line = scanner.nextLine();
    if (line.equals("$")) {
      list.add(builder.toString());
      builder.setLength(0);
    } else {
      builder.append(line).append("\r\n");
    }
  }
} catch (FileNotFoundException e) {
  e.printStackTrace();
}

问题在于它如何读取转义序列” “在不同的 Spring Boot 版本中。我通过替换来修复它” “ 和 ” ”

此异常看起来像是您的文件传输过程被意外中断。

请检查您的网络连接，您应该在代码中捕获此异常，清理文件上传状态，然后重新上传文件。

像往常一样，你应该学习如何实现“http文件传输恢复”。当然，这会增加你的代码复杂性:)
