File uploads in spring MVC

The required racks for uploading files using Commons-fileupload are: Commons-fileupload and Common-io two Rack pack support, which can be smashed on the Apache website.

To configure uploads in profile Spring-mvc.xml:

<id= "Multipartresolver"        class= " Org.springframework.web.multipart.commons.CommonsMultipartResolver ">//File Upload max is how much

        <name= "Maxuploadsize"  value= "10485760000"/ >//Upload file encoding method

        <name= "defaultencoding"  value= "Utf-8"/>// Maximum cache size in memory

        <name= "Maxinmemorysize"  value= "40960"/>  </bean>

In the corresponding JSP page there are two main points to note, asked form form the method= "post" and enctype= "Multipart/form-data", the others are usually written.

The corresponding code in the controller that is submitted to spring MVC is as follows:

@RequestMapping (value= "/upload.do", method=requestmethod.post)    publicthrows  ioexception{        for(multipartfile file:files) {            if(!  File.isempty ()) {            new File ("E:/file" +file.separator+file.getoriginalfilename ())}        }         return "Uploadok";    }

Adding @requestparam code in the main is to deal with multiple files when uploading, if it is a single file upload can not be written.
