下载文件示例
闲来无事做了个文件下载的功能，这还是第一次做的说，不知道会不会遭BS。
请自备jQuery环境。
(function($){var _cf = window["configFile"] = {LoginModel:function () {}};_cf.LoginModel.prototype={/*** 下载配置文件*/downloadBk : function(fBKName,mosn){var action = window["path"]+"/bk_downloadBk.action";var $form = $('<form id="downloadBk" method="get" action="'+action+'"></form>');$form.append('<input type="hidden" name="fBKName" value="'+fBKName+'" />');$form.append('<input type="hidden" name="mosn" value="'+mosn+'" />');$form.append('<input type="hidden" name="random" value="'+Math.random()+'" />');$('body').append($form);$form[0].submit();$('#downloadBk').remove();}};})(jQuery);<action name="bk_*" method="{1}"type="stream"><param name="contentType">application/octet-stream</param><param name="inputName">inputStream</param><param name="contentDisposition">attachment;filename="${fileName}"</param><param name="bufferSize">4096</param></result></action>public String downloadBk(){return "download";}public InputStream getInputStream(){LOG.info("start to download:"+fBKName);InputStream is=null;try {BKViewMgr bMgr = new BKViewMgr(dmsn);String fbkPath=bMgr.getCompareFilePath(fBKName,mosn);LOG.info("fbkPath:"+fbkPath);return new FileInputStream(fbkPath);} catch (FileNotFoundException e) {LOG.info("没有指定文件");}LOG.info("end to download:"+fBKName);return is;}public String getFileName(){String fileName=fBKName;try {return new String(fileName.getBytes(),"ISO8859-1");} catch (UnsupportedEncodingException e) {LOG.info("不支持的编码格式",e);}return "";}
