I have tried to solve this problem for 3 days and still getting the same error. I am trying to make a register/login spring mvc app. But it throw the exception when clicked on register button. Please help me to get it resolved. Thanks.

HTTP Status 500 – Internal Server Error
Type Exception Report
Message Failed to parse multipart servlet request

Exception
org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request
............
Root Cause
java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided........

Here is the controller:

@Controller
@MultipartConfig
public class RegistrationController extends HttpServlet {
    @Autowired
    public EmployeeService employeeService;

@Controller
@MultipartConfig
public class RegistrationController extends HttpServlet{
   @RequestMapping(value="/register", method=RequestMethod.GET)
   public ModelAndView mav = new ModelAndView("register");
   mav.addObject("employee", new Employee());
   return mav;
}

@RequestMapping(value="/register", method=RequestMethod.POST)
public MOdelAndView addUser(HttpServletRequest request, HttpServletResponse response, @ModelAttribute("employee") Employee employee, @RequestParam MultipartFile photo){
   employeeService.register(employee, photo);
   return new ModelAndView("register","msg","Employee registered successfully");
}
}

The register.jsp page:

<form:form id="regForm" modelAttribute="employee" action="registerProcess" method="post"
           enctype='multipart/form-data'>
...........
<tr>
                <td><form:label path="photo">Employee Photo</form:label></td>
                <td><form:input type="file" path="photo" name="photo" id="photo" /></td>
            </tr>
            <tr>
                <td></td>
                <td><form:button class="btn btn-primary" id="register" name="register">Register</form:button></td>
            </tr>
        </table>
    </form:form>

Also, I have provided this in web.xml

  <filter>
    <filter-name>MultipartFilter</filter-name>
    <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>MultipartFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

And application.properties,

   spring.servlet.multipart.max-file-size=10MB
   spring.servlet.multipart.max-request-size=10MB

and in context.xml inside resources
<Context allowCasualMultipartParsing="true"></Context>

I have tried already given answers in stackoverflow and other sites, but no change in error. Sometimes it’s just threw 404.
