直播意外結束

Question

我不斷收到 MalformedStreamException
我正在使用 Java 8 運行 tomcat 9
客戶端正在發送分段文件上傳（圖片和圖片名稱）
這是函數簽名：

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

這是 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 multipart 的代碼正在使用 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);

這是我到目前為止嘗試過的：
我將公共文件上傳升級到 1.3.3
將 java 升級到 1.8
升級 tomcat 到 9
一些帖子建議在 tomcat 中設置 maxSowllowSize - 所以我將它設置為 -1 沒有幫助......
網絡連接良好（在 wifi 和互聯網上均使用小文件進行測試）
提交代碼

Answer 1

我有一個類似的問題，一些更大的請求或文件上傳導致“流意外結束”錯誤。

原來這是由於 Tomcat 9.0.31 並升級它解決了這個問題。 這篇文章更詳細地解釋了它。

編輯：如果您使用的是使用 Tomcat 9.0.31 的 Spring 或 Spring Boot 版本，請嘗試升級到使用較新 Tomcat 版本的版本。

Answer 2

此異常看起來像您的文件傳輸過程已意外中斷。

請檢查您的網絡連接，您應該在代碼中捕獲此異常，清理文件上傳狀態，然后重新上傳文件。

像往常一樣，你應該學習如何實現“http文件傳輸恢復”。當然，這會增加你的代碼復雜度:)
