Could not parse multipart servlet request, nested exception is org.apache.commons.fileupload.FileUploadException

问题:

I am getting error when i uploading 10 MB Size of csv file in Spring by using CommonsMultipartResolver library. I have done following setting in xml file Xml File Confi :

 <beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 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 --> 

Controller Code:

 @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);     } } 

Form Page:

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

But I am not understanding what is issue. I tried to set up size and setting header also enctype="multipart/form-data", but yet not resolved.

Given below are error:

Change your controller method handler signature to work like:

From:

@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 { 

To:

@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"; } 

and in BillingAndRecon class add mulitpart/binding fields like:

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

Note: BindingResult argument should be after immediate of @ModelAttrubiute/@RequestBody

and jsp form:

<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> 

and don't forget to add for binding instance in GET handler like:

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