问题：

文件上载中断时“无法解析多部分servlet请求”

骆照
2023-03-14

我正在使用Spring Boot（1.5.7）和ng2文件上传（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（例如关闭浏览器选项卡），Spring Boot会记录下一个错误（两次）：

2018-10-10 14:45:57.054 ERROR 11540 --- [http-nio-8282-exec-6] o.a.c.c.C.[.[.[.[dispatcherServlet]      : line[182] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed.

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);
}

和应用程序的下一个属性。属性：

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

现在，当文件上载中断时，@ExceptionHandler会按照应该的方式记录错误（下一个代码段），但在Spring Boot之后，仍然会不时从dispatcherServlet记录错误（如第一个代码段中所示）

以下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();
        };

我不知道会出什么问题。先谢谢你。

另外，我注意到，如果@ExceptionHandler方法类型为void，并且除了记录错误之外什么都不做，那么一切都会正常工作

更新

我认为这没关系，因为控制器甚至没有被调用，因为我知道它会发生，因为文件首先上传到服务器（在这一步会引发异常），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

这是chaned@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，异常日志作为WARN记录两次。如果早期是我的WARN日志Spring Boot重复ERROR日志，现在是我的WARN日志重复（时间不同）

@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);
        }
    }

在您的Web安全配置适配器中禁用csrf，我不确定这是什么，但我的一位专家朋友说禁用它可以发送多部分资源。

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

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

以下是我可以看到的两种解决方案，它们对我有效。。

方法1返回响应实体

@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相似但返回字符串

    @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();
    }

我认为这种行为是正确的，因为您仍然在这里记录异常（e参数）：

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

请注意，您的异常已从ERROR更改为WARN，就像您在yout异常处理程序中以WARN形式记录一样。
