无法解析多部分servlet请求，嵌套异常为org.apache.commons.fileupload.FileUploadException

通过使用CommonsMultipartResolver库在Spring中上传10 MB大小的csv文件时遇到错误。我已经在xml文件Xml File
Confi中进行了以下设置：

 <beans:bean id="multipartResolver"><!-- max upload size in bytes --><beans:property name="maxUploadSize" value="99971520" /> <!-- 99MB --><!-- max size of file in memory (in bytes) --><beans:property name="maxInMemorySize" value="1048576" /> <!-- 1MB -->

控制器代码：

 @RequestMapping(value="/uploadForm",method = RequestMethod.POST)public @ResponseBody  String  uploadForm1(@ModelAttribute("admin") BillingAndRecon  billingandrecon,@RequestParam String id,BindingResult result,Principal principal,@RequestParam MultipartFile file,HttpSession session) throws ServiceException, DaoException, IllegalStateException, IOException {    File uploadFile = null;    String msg = "";    if (!file.getOriginalFilename().equals("")) {        logger.info("Before  Multipart file get path >> ");        BillingAndReconServiceImpl asi = (BillingAndReconServiceImpl) this.billingAndReconService;// not correct!!        String uploadDirectoryPath = asi.getUploadDirectoryPath(); // not correct!!        uploadFile = new File( uploadDirectoryPath + file.getOriginalFilename());        logger.info("Before  Multipart file get path uploadDirectoryPath >> "+uploadDirectoryPath);        file.transferTo(uploadFile);    }}

表单页面：

<form:form action="./uploadForm" method="post" enctype="multipart/form-data" ModelAttribute=="admin">          <input type="file" name="file" />          <input type="text" name="id" />           </form:form>

但是我不明白什么是问题。我也尝试设置大小和设置标头enctype="multipart/form-data"，但尚未解决。

以下是错误：

小编典典

正如 @ChristianMaioliM 在评论中所要求的那样，添加了有关以下内容的更多详细信息：代码中的问题是
BindingResult参数未遵循模型对象 。

Errors或BindingResult参数必须跟随立即绑定的模型对象，因为方法签名可能具有多个模型对象，并且Spring将为它们中的每个对象创建一个单独的BindingResult实例，因此以下示例将不起作用

参考docs
BindingResult和@ModelAttribute的无效顺序

要解决此问题，请更改您的控制器方法处理程序签名，以遵循BindingResult和模型对象之间的参数顺序，例如：

从：

@RequestMapping(value="/uploadForm",method = RequestMethod.POST)public @ResponseBody  String  uploadForm1(@ModelAttribute("admin") BillingAndRecon  billingandrecon,@RequestParam String id,BindingResult result,Principal principal,@RequestParam MultipartFile file,HttpSession session) throws ServiceException, DaoException, IllegalStateException, IOException {

至：

@RequestMapping(value="/uploadForm",method = RequestMethod.POST)public String  uploadForm1(            @ModelAttribute("admin") BillingAndRecon billingandrecon,             BindingResult result,            Principal principal,            HttpSession session) throws ServiceException, DaoException, IllegalStateException, IOException {  //do file save here  return "some-view-name";}

并在BillingAndRecon类中添加mulitpart / binding字段，例如：

public class BillingAndRecon {  private MultipartFile file;  private String id;  no-arg constructor;  getters;  setters;}

注意： BindingResult参数应在@ModelAttrubiute/@RequestBody

和jsp形式：

<form:form action="${pageContext.request.contextPath}/uploadForm"     method="post"    enctype="multipart/form-data"    modelAttribute="admin">      <input type="file" name="file" />      <form:input path="id" /></form:form>

并且不要忘记在GET处理程序中添加绑定实例，例如：

@RequestMapping(value="/uploadForm",method = RequestMethod.GET)public String uploadFormView(Model model){  model.addAttribute("admin", new BillingAndRecon());  return "your-upload-view-name";}

Apache Commons FileUpload 1.3.1 发布

Apache Commons FileUpload 1.3.1 发布，这是一个安全补丁版本，修复了编号为 CVE-2014-0050 的一个 DoS 安全漏洞。

下载地址：http://commons.apache.org/proper/commons-fileupload/download_fileupload.cgi

Apache Commons FileUpload 1.3.2 发布

Apache Commons FileUpload 1.3.2 发布了。

Apache Commons FileUpload 使用最为广泛的Java文件上传组件，Struts本身采用这个包来处理文件上传。文档非常详细、简单易用。

详情：http://commons.apache.org/proper/commons-fileupload/

Apache Commons FileUpload 1.3.3 发布

Apache Commons FileUpload 1.3.3 已发布。

Apache Commons FileUpload 库解析符合 RFC 1867 （HTML 中基于表单的文件上传）的 HTTP 请求。也就是说，如果使用 POST 方法提交了 HTTP 请求，并且内容类型为 “multipart / form-data”，则 FileUpload 可以解析该请求，并以调用者轻松使用的方式使结果可用。

此版本唯一的更改是：

FILEUPLOAD-279：为了安全起见，DiskFileItem 不能再反序列化，除非设置了特定的系统属性。
