示例1: getStream

import com.vaadin.server.DownloadStream; //导入依赖的package包/类
/**
 * Gets the stream.
 *
 * @return the stream
 */
/*
 * (non-Javadoc)
 * 
 * @see com.vaadin.terminal.StreamResource#getStream()
 */
@Override
public DownloadStream getStream() {
	final DownloadStream stream = new DownloadStream(getStreamSource().getStream(), this.contentType,
			this.filename);
	stream.setParameter("Content-Disposition", "attachment;filename=" + this.filename);
	// This magic incantation should prevent anyone from caching the data
	stream.setParameter("Cache-Control", "private,no-cache,no-store");
	// In theory <=0 disables caching. In practice Chrome, Safari (and,
	// apparently, IE) all
	// ignore <=0. Set to 1s
	stream.setCacheTime(1000);

	return stream;
