uploadify文件上传以及预览

来源：互联网发布：java jdk jre下载官网编辑：程序博客网时间：2024/06/07 12:20

项目中利用poi实现预览基本步骤:（其他的导入jar包什么的在别人资料上可以找到，我实现这个功能也是借鉴+实践才成功的~我提供的只是我接触项目的思路和代码。见谅！【滑稽】）

先pdf，然后swf

安装OpenOffice后启动cmd：C:/Program Files (x86)/OpenOffice 4/program/soffice.exe -headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\"

安装路径：C:/Program Files (x86)/OpenOffice 4/program/soffice.exe ；

1.（jsp页面中）项目中uploadify上传js格式

使用uploadify需要导入uploadify.css、jquery.uploadify.min.js等jar包，在官方domes有，嗯，有，还有各种属性；

$('#file_upload').uploadify({'swf' : '${ctx}/js/uploadify3.2.1/uploadify.swf','uploader':'${ctx}/upload/uploadAction!uploadFile?jsessionid='+"<%=request.getParameter("fkId")%>",'buttonText' : '添加,'buttonClass' : 'uploadify','fileObjName' : 'uploadify','formData' : {'fkId' : '${fkId}'},        'onUploadSuccess' : function(file, data, response) {                }});});

2.js中调用预览的方法（只是提供一个js方法，放在jsp那里自己看咯）

function preview(id) {var param = '';if(typeof id!='undefined')param = '&id='+id;var url='${ctx}/jsp/file/documentView.jsp?fkId='+fkId+param;window.top.art.dialog.open(url,{title:"在线预览",width:'80%',height:'90%',lock:true,opacity:0.3,button: [ { name: '关闭', callback: function () {return true; }, focus: true }]});}

3.documentView.jsp页面(项目数据)上面js方法中在线预览内填充的页面

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%><%@ include file="/common/taglibs.jsp"%><%@ include file="/common/jqueryhead.jsp" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html style="height: 100%;width: 100%;">    <head>         <title></title>                 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />         <style type="text/css"> html, body{ height:100%; }body { margin:0; padding:0; overflow:hidden; }   /* #flashContent{display: none;} */#imgFile{width: 100%;height: 100%;display: none;}.module{display: none;}        </style> <script type="text/javascript" src="${ctx}/jsp/file/js/swfobject/swfobject.js"></script><script type="text/javascript" src="${ctx}/jsp/file/js/flexpaper_flash.js"></script><script type="text/javascript">var imgSuffix="bmp,jpeg,gif,psd,png,tiff,tga,eps,jpg";//常用图片文件格式var mp4Suffix="mp4,avi,flv,rmvb,3gp";//常用视频格式var officeSuffix="txt,doc,xls,ppt,pdf,dwg,exb,docx,xlsx,pptx,wps,et,dps,html,xml,swf";$(function(){var fkId="${param.fkId}";var ids="${param.id}";console.log("documentView.jsp:"+fkId+"-----");//var ids="${param.id}";//读取文件格式$.ajax({url:'${ctx}/upload/uploadAction!getFileStaff?ids='+ids,type:'post',data: "idd="+fkId ,async:false,success:function(data){console.log(data);data=eval('('+data+')');if(data.isExists=="false"){loadNoP(1);//文件不存在}else{var id=data.id;var pt=data.realName;var staff=data.extension;//文件格式console.log(id+"--"+staff+"==="+officeSuffix.indexOf(staff)+"----"+imgSuffix.indexOf(staff));if(imgSuffix.indexOf(staff)!=-1){//是否是图loadImage(pt);}else if(officeSuffix.indexOf(staff)!=-1){//可预览loadDocument(pt);}else{loadNoP(0);}}}});});/***预览图片 不需要转换*/function loadImage(pt){$(".module").hide();console.log(pt+"////");/* $("#imgFile").find("img").attr("src","${ctx}/downQybzh/downQybzhAction!preview?fkId=${param.id}"); */ $("#imgFile").find("img").attr("src",pt);$("#imgFile").show();}/**不能预览**/function loadNoP(status){$(".module").hide();if(status==1){$("#imgFile").find("img").attr("src","${ctx}/jsp/file/notExistsFile.jpg").attr("width","100%").attr("height","100%");}else{$("#imgFile").find("img").attr("src","${ctx}/jsp/file/descpreview.jpg").attr("width","100%").attr("height","100%");}$("#imgFile").show();}/***需要转换*/ <%-- function loadDocument(){ $("#emb").attr("src","<%=session.getAttribute("swfpath")%>");$(".module").hide();$("#flashContent").show();}  --%>function loadDocument(pt){console.log("loadDocument:"+pt);var fkId="${param.fkId}";var swfVersionStr = "9.0";//版本            var xiSwfUrlStr = "${ctx}/jsp/file/js/swfobject/expressInstall.swf";//播放器            var flashvars={};            flashvars = {             //swf相对路径                    //SwfFile 后跟项目下的图片路径",   SwfFile : decodeURI(pt),  //SwfFile:escape('/pipe/upload/626ea0ed1e844eb5973005474701acdd测厚管线清单与记录201704.swf'),  Scale : 0.8,//Scale是0-1之间的数，表示显示的放大参数    ZoomTransition : "easeOut",                ZoomTime : 0.5,          ZoomInterval : 0.1,    FitPageOnLoad : false,    FitWidthOnLoad : true,    FitHeightOnload : true,    PrintEnabled : false,    FullScreenAsMaxWindow : false,    ProgressiveLoading : true,   // PrintToolsVisible : false,    ViewModeToolsVisible : true,    ZoomToolsVisible : true,    FullScreenVisible : true,    NavToolsVisible : true,    CursorToolsVisible : true,    SearchToolsVisible : true,  WMode:"transparent",      localeChain: "en_US",  }; var params = {    };            params.quality = "high";            params.bgcolor = "#999999";            params.allowscriptaccess = "sameDomain";            params.allowfullscreen = "true";            var attributes = {};            attributes.id = "FlexPaperViewer";            attributes.name = "FlexPaperViewer";            swfobject.embedSWF(                "FlexPaperViewer.swf", "flashContent",                 "100%", "100%",                swfVersionStr, xiSwfUrlStr,                 flashvars, params, attributes);swfobject.createCSS("#flashContent", "display:block;text-align:left;");$(".module").hide();$("#flashContent").show();};        </script>     </head>     <body style="height: 100%;width: 100%;">    <center>    <div style="height: 100%;width: 100%">    <!-- 需要转换的 -->        <div id="flashContent" class="module" style="height: 100%;width: 100%;" >        这里是预览        <!-- <EMBED id="emb" src="" style="height: 100%;width: 100%" type=application/x-shockwave-flash wmode="transparent "quality="high "></EMBED> -->        </div>        <!-- 图片预览 -->        <div id="imgFile" class="module"  style="height: 100%;width: 100%">        <img src="" width="100%" height="100%"/>        </div>         <!-- 视频预览 -->        <div id="mp4Play" class="module" style="height: 100%;width: 100%" >       <iframe width="100%"  height="100%" frameborder="0" scrolling="no">              </iframe>    </div>        </div>        </center>   </body> </html>

4.后台判断后缀方法

后面的两行代码：

String json = new JsonMapper().toJson(ufi);
Struts2Utils.renderText(json);

只是转json数据格式；

public void getFileStaff() {fkId=request.getParameter("idd");Map<String, String> map = new HashMap<String, String>();map.put("fkId", fkId);List<UploadFileInfo> ufis = uploadFileInfoService.query(map);UploadFileInfo ufi = null;ufi = uploadFileInfoService.getById(request.getParameter("ids"));if (ufi != null) {String paths=null;try {paths=Encoding.encode(ufi.getName(), "UTF-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();}ufi.setIsExists("true");File file = new File(ufi.getDirectory() +request.getParameter("idd")+ paths);if (!file.exists()) {ufi.setIsExists("false");// 文件不存在uploadFileInfoService.delete(ufi.getId());}String converfilename = (ufi.getDirectory() +request.getParameter("idd")+ paths).replaceAll("\\\\", "/");String[] str={"bmp","jpeg","gif","psd","png","tiff","tga","eps","jpg"};String ext=ufi.getExtension();//判斷是否包含extboolean isContains = Arrays.asList(str).contains(ext);if(isContains){String realname=(request.getParameter("idd")+ paths).replaceAll("\\\\", "/");ufi.setRealName("/pipe/upload/"+realname);}else{DocConvert d=new DocConvert(converfilename);System.out.println("lujingming:"+d);d.conver();d.getswfPath();String swfpath = "/pipe/upload"+d.getswfPath().substring(d.getswfPath().lastIndexOf("/"));  System.out.println("打印后的路径："+d.getswfPath());System.out.println("项目里的路径："+swfpath);ufi.setRealName(swfpath);}} else {ufi = new UploadFileInfo();ufi.setIsExists("false");// 文件不存在}String json = new JsonMapper().toJson(ufi);Struts2Utils.renderText(json);}

5.工具类DocConvert

在上面判断的方法中调用此类，用来启动OpenOffice应用，进而转换格式；

       }        /**        * 初始化        * @param fileString        */        private void ini(String fileString) {            this.fileString = fileString;            fileName = fileString.substring(0, fileString.lastIndexOf("."));

   System.out.println("PDF文件路径"+docFile);        if (docFile.exists()) {                if (!pdfFile.exists()) {                           // 调用openoffice服务线程                     String command = "C:/Program Files (x86)/OpenOffice 4/program/soffice.exe -headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\"";                     Process p = Runtime.getRuntime().exec(command);             // 连接openoffice服务              // OpenOfficeConnection connection = new SocketOpenOfficeConnection(Integer.valueOf(Property.getProperty("port")));    //服务端口 port            OpenOfficeConnection connection = new SocketOpenOfficeConnection("127.0.0.1", 8100);            try {                        connection.connect();                        DocumentConverter converter = new OpenOfficeDocumentConverter(connection);                        converter.convert(docFile, pdfFile);                        // close the connection                        connection.disconnect();                     // 关闭进程                    p.destroy();                    System.out.println("****pdf转换成功，PDF输出：" + pdfFile.getPath()+ "****1");                    } catch (java.net.ConnectException e) {                        e.printStackTrace();                        System.out.println("****swf转换器异常，openoffice服务未启动！****2");                        throw e;                    } catch (com.artofsolving.jodconverter.openoffice.connection.OpenOfficeException e) {                        e.printStackTrace();                        System.out.println("****swf转换器异常，读取转换文件失败****3");
