org.springframework.web.multipart.MultipartException:

在做文件上传的时候遇到这个错误：

org.springframework.web.multipart.MultipartException: 

接下来给出解决方法：

1.是否配置了

          id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

         2.       form是否设置了

          id="fileupload" method="post" enctype="multipart/form-data">

         3.      方法里

         @RequestMapping(value = "/upload.do",headers = "content-type=multipart/*", method = RequestMethod.POST)  
	    public String upload(@RequestParam(value = "file", required = false) MultipartFile file, MultipartHttpServletRequest  request, ModelMap model) { 

         4.      依赖jar包

1. commons-fileupload.jar
2. commons-io.jar
