Class CommonsFileUploadService

java.lang.Object
  org.apache.click.service.CommonsFileUploadService

All Implemented Interfaces:

FileUploadService

public class CommonsFileUploadService
extends Object
implements FileUploadService

Provides an Apache Commons FileUploadService class.

To prevent users from uploading exceedingly large files you can configure CommonsFileUploadService through the properties sizeMax and fileSizeMax.

For example:

 <file-upload-service>
     <!-- Set the total request maximum size to 10mb (10 x 1024 x 1024 = 10485760). -->
     <property name="sizeMax" value="10485760"/>

     <!-- Set the maximum individual file size to 2mb (2 x 1024 x 1024 = 2097152). -->
     <property name="fileSizeMax" value="2097152"/>
 </file-upload-service> 

Note that this is a global configuration and applies to the all file uploads of the application.

If you would like to specify a custom FileUploadService implementation use the classname attribute:

 <file-upload-service classname="com.mycorp.util.CustomFileUploadService">
     <property name="customProperty" value="customValue"/>
 </file-upload-service>
