gwt使用apache-commons-fileUpload,轻松实现文件上传
gwt使用apache-commons-fileUpload,轻松实现文件上传，图片上传等功能。?1.gwt 前端页面（可以做成组建，供各个模块调用）FormPanel formPanel ?= new FormPanel(); ?formPanel.setAction("/uploadImage"); ???formPanel.setEncoding(FormPanel.ENCODING_MULTIPART); ?formPanel.setMethod(FormPanel.METHOD_POST); ???FlowPanel panel = new FlowPanel(); ?formPanel.setWidget(panel); ???FileUpload fileUpload = new FileUpload(); ?fileUpload.setName("file"); ?panel.add(fileUpload); ?ok,formpanel触发sumbit即可。下面便是servlet端的实现。 ? ? ? ? ???2.servlet端FileItemFactory factory = new DiskFileItemFactory(); ? ??ServletFileUpload upload = new ServletFileUpload(factory); ? ??? ??List items = null; ? ??? ??try { ? ??? ? items = upload.parseRequest(request); ? ??} catch (FileUploadException ex) { ? ??? ? throw new ServletException(ex); ? ??} ? ??? ??Iterator iter = items.iterator(); ? ??? ??while (iter.hasNext()) { ? ??? ? FileItem item = (FileItem) iter.next(); ? ??? ? if (item.isFormField() == false) { ? ??? ? ? ? ?//获得byte数组 ?? ? ? ? byte[] bytes = item.get(); ?? ? ? ? //或直接保存成文件 ?? ? ? ? File file = new FIle("D:/temp",item.getName()); ? ? ?? ? ? ? item.write(file);//直接保存文件 ? ? ? ? ?? ? } ? ??} ?? 1 楼 ccx410 2011-12-19 安装gwt报错，unable to retrieve osgi.bundle,com.google.gwt.eclipse.sdkbundle如何解决
