Class MaxUploadSizeExceededExceptionResolver

java.lang.Object

com.communote.server.web.commons.resolver.MaxUploadSizeExceededExceptionResolver

All Implemented Interfaces:

org.springframework.web.servlet.HandlerExceptionResolver

public class MaxUploadSizeExceededExceptionResolver
extends Object
implements org.springframework.web.servlet.HandlerExceptionResolver

Exception resolver that handles the MaxUploadSizeExceededException occurring during multipart request resolution. The handler provides a localized error message to the view which can be defined using request-mappings. The error message is available under the attribute MessageHelper.ERROR_MESSAGES_KEY. If there is no mapping for a request it will be interpreted as an AJAX request and the response will be a JSON object holding the error message. If the requests Accept header does not include application/json the JSON response should be bundled in HTML. This must be handled by the view provided with #setAjaxResponseView(String).
