Required multipartfile parameter ' file ' is not present error

It is usually uploaded using the Springmvc file to report the error.

There are a number of reasons why the form parameter and the control method parameter are inconsistent, for example:

<input type= "File" Name= "Filemedia" id= "MediaFile"/>

@RequestMapping (value = "/uploadmedia", method = Requestmethod.post)
Public Modelandview Uploadmedia (@RequestParam multipartfile file,model model,httpservletrequest request, HttpServletResponse response) {
.........

........

}

It is also possible to submit a form using the button buttons and then control the submission form, for example:

<button onclick= "Uploadmedia ()" style= "width:70px;" > OK </button>

Switch

<input type= "button" onclick= "Uploadmedia ()" style= "width:60px;height:35px;" value= "OK"/>

You can do it.
