File Upload using Spring MVC
I am new to Spring MVC though not new to Java and working primary on Struts2 and Wicket as my choice for web development
I am trying to do a POC of file upload using spring MVC here is my jsp file
<form id="fileuploadForm" action="fileupload" method="POST" enctype="multipart/form-data" >
<fieldset>
<legend>Upload Fields</legend>
<input id="file" type="file" name="file" />
<p><button type="submit">Upload</button></p>
</fieldset>
</form>
and my Controller is
@Controller
@RequestMapping("FileUpload/fileupload")
public class FileUploadController{
public ModelAndView processUpload(@RequestParam MultipartFile file, WebRequest webRequest, Model model) {
String orgFileName = file.getOriginalFilename();
String filePath = "data/input" + orgFileName;
ModelMap modelMap = new ModelMap();
System.out.println("*******************************************");
File dest = new File(filePath);
try {
file.transferTo(dest);
} catch (IllegalStateException e) {
e.printStackTrace();
modelMap.addAttribute("result", "File uploaded failed:" + orgFileName);
return new ModelAndView("results", modelMap);
//return "File uploaded failed:" + orgFileName;
} catch (IOException e) {
e.printStackTrace();
modelMap.addAttribute("result", "File uploaded failed:" + orgFileName);
return new ModelAndView("results", modelMap);
}
modelMap.addAttribute("result", "File uploaded " + orgFileName);
return new ModelAndView("results", modelMap);
}
below is the entry for dispatcher-servlet.xml

Thanks in advance
There are several things to note:
- You have mapped only URLs ending on
.htm
to your Spring Dispatcher, so the Controller can never see your request. - If
FileUpload
is the name of your Web-App, you need to remove it from the@RequestMapping
annotation. <bean name="/*" class="com.app.controller.FileUploadController"/>
should be changed to<bean name="/fileupload.htm" class="com.app.controller.FileUploadController"/>
HTH
I'm always starting my mappings with a forward slash, so try:
@RequestMapping("/FileUpload/fileupload")
