文件上传中断时“解析多部分 servlet 请求失败”

【问题标题】："Failed to parse multipart servlet request" when file uploading interrupted文件上传中断时“解析多部分 servlet 请求失败”
【发布时间】：2019-03-15 08:58:56
【问题描述】：

我正在使用 Spring Boot (1.5.7) 和 ng2-file-upload (1.2.1) 将文件上传到服务器。

所以我遇到了下一个问题，当文件上传开始并中断时（例如在关闭浏览器选项卡上）Spring Boot 记录下一个错误（两次）：

当我将@ExceptionHandler 添加到@ControllerAdvice 时：

@ExceptionHandler(MultipartException.class)
protected ResponseData handleFileUploadingError(Exception e) {
    log.warn("Failed to upload attachment", e);
    return ResponseData.with(e.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
}

以及 application.properties 的下一个属性：

spring.mvc.throw-exception-if-no-handler-found=true

现在，当文件上传中断时，@ExceptionHandler 会记录错误（下一个 sn-p），但在此之后 Spring Boot 仍然会从 dispatcherServlet 记录错误（就像在第一个 sn-p 中一样）

这是前端应用程序响应文件上传的部分代码：

this.uploader.onAfterAddingFile = (fileItem) => {
            this.setAuthTokenHeader();
            this.uploader.uploadItem(fileItem);
            this.uploadedFiles.push({
                id: null,
                originalName: fileItem.file.name,
                attachmentName: null
            });
            this.changedCallback(this.uploadedFiles);
            this.scrollToFilesUX();
        };

我不知道有什么问题。提前致谢。

PS：我还注意到，如果 @ExceptionHandler 方法类型为 void，它只会记录错误一切正常

更新

我认为这没关系，因为控制器甚至没有被调用，因为我知道这是因为文件首先上传到服务器（并且在这一步引发异常）然后控制器执行。但这是我的控制器方法（类注释为@RestController）：

@PostMapping(value = "/attachments")
    public ResponseData put(@RequestParam(value = "storeFile", required = false) MultipartFile multipartFile,
                            @RequestParam(required = false) List<DocumentType> documentTypes) throws IOException {
        try {
            return ResponseData.with(attachmentService.uploadTempFile(multipartFile, documentTypes));
        } catch (AttachmentValidationException e) {
            return ResponseData.with(e.getTempFileName(), e.getMessages(), HttpStatus.NOT_ACCEPTABLE);
        }
    }

更新 2

这里是 @ExceptionHandler 方法。在这种情况下，Spring Boot 不会记录任何错误（这很好）。但是现在，异常记录为 WARN 两次。如果早期是我的 WARN 日志 + Spring Boot 重复错误日志，那么现在是我的 WARN 日志重复（不同时间）

@ExceptionHandler(value = MultipartException.class)
    public void handleFileUploadingError(HttpServletResponse response, Exception exception) {
        log.warn("Failed to upload attachment", exception);
        try {
            response.sendError(Response.SC_INTERNAL_SERVER_ERROR, exception.getMessage());
        } catch (IOException e) {
            log.error("Failed to send error response", e);
        }
    }

【问题讨论】：

  • 能否分享您的控制器映射和功能定义？如果您从浏览器向我们分享网络选项卡请求也很棒
  • 你能把它公开“public ResponseData handleFileUploadingError”
  • @kj007 不幸的是它没有帮助。 Spring Boot 有时仍会记录（并重复）该错误
  • @DmitryStoyanov please catch @ExceptionHandler({MultipartException.class, IOFileUploadException}) 应该可以帮助您仅登录控制器建议，因为可能会在 MultipartException 之前按顺序调用 IOFileUploadException ..
  • @kj007 不幸的是，它也无济于事。看看我的Update 2，也许你能找到提示

标签： java spring angular rest multipart


【解决方案1】：

我认为这种行为是正确的，因为您仍在此处记录异常（e 参数）：

log.warn("Failed to upload attachment", e);

请注意，您的异常已从 ERROR 更改为 WARN，因为您确实在异常处理程序中记录为警告。

【讨论】：

  • 也许我没听懂你的意思，但我的麻烦是，在我的 WARN 日志之后，Spring Boot 有时也会记录 ERROR，我的 @ExceptionHandler 似乎没有发现那个错误。对我来说，解决方案将只是 ExceptionHandler 错误日志
  • @DmitryStoyanov 我现在明白了。
【解决方案2】：

我已经调试了你的控制器建议，发现方法被调用了两次，所以它的日志记录警告两次，所以似乎 sendError 再次发送响应以处理异常..（不确定）..

这里有两个解决方案，我可以看到并为我工作。..

方法1返回ResponseEntity

@ExceptionHandler(MultipartException.class)
    public ResponseEntity handleFileUploadingError(MultipartException exception) {
        log.warn("Failed to upload attachment", exception);
        return new ResponseEntity<>(exception.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);

    }

方法2类似但返回字符串

    @ExceptionHandler(value = MultipartException.class)
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    @ResponseBody
    public String handleFileUploadingError(MultipartException exception) {
        logger.warn("Failed to upload attachment", exception);
        return exception.getMessage();
    }

【讨论】：

  • 这两种解决方案都不能解决我的问题。 Spring Boot sometime 仍然记录错误。看起来异常抛出了两次，但只捕获了一次，在我的 UPDATE 2 异常中捕获了两次。但是我有下一个问题，为什么这个异常会抛出两次，也许响应有些麻烦？因为如果@ExceptionHandler 是无效的并且没有实现任何逻辑而不是“log.warn(...);”一切正常（使用 WARN 立即记录错误）
【解决方案3】：

经过多次尝试，经过多次眼泪。我随机找到了如何解决这个错误。所有的麻烦都是来自服务器端的响应。如果响应不包含正文 - 一切正常，否则一切正常，如本主题的标题。有我的 ExceptionHandler 可以解决主题案例：

@ExceptionHandler(value = MultipartException.class)
public ResponseData handleFileUploadingError(Exception exception) {
    log.warn("Failed to upload attachment", exception);
    return ResponseData.with(HttpStatus.BAD_REQUEST);
}

【讨论】：

    【解决方案4】：

    在您的 WebSecurityConfigurerAdapter 中禁用 csrf 我不确定这是什么，但我的一位专家朋友说禁用它以发送多部分资源。

    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
}

    【讨论】：

      【解决方案5】：

      检查您的表单是否有 method="post" enctype="multipart/form-data"。另外，请检查您是否在 ajax 参数中提供了这些设置。

      type:'post',
processData : false,
contentType : false,
mimeType: 'multipart/form-data',
