swfupload 上传文件

1、swfupload 包

2.

2.代码编写

??????????????? swfu = new SWFUpload({
?? ??? ??? ??? ?upload_url: "<%=path %>/courseManage/saveCourseware.action",? //上传文件的action
?? ??? ??? ??? ?file_post_name : "courseware",//action 接收的文件File

?? ??? ??? ??? ?file_upload_limit : "0",???? //上传文件的限制，如果为0 则不限制
?? ??? ??? ??? ?file_size_limit : '0 MB',??? //文件大小
?? ??? ??? ??? ?file_types : '*.*',
?? ??? ??? ??? ?file_types_description : '所有文件',?? ??? ??? ?
?? ??? ?
?? ??? ??? ??? ?file_queue_error_handler : fileQueueError,
?? ??? ??? ??? ?file_dialog_complete_handler : fileDialogComplete,//选择好文件后提交
?? ??? ??? ??? ?file_queued_handler : fileQueued,
?? ??? ??? ??? ?upload_progress_handler : uploadProgress,
?? ??? ??? ??? ?upload_error_handler : uploadError,
?? ??? ??? ??? ?upload_success_handler : function(file,serverData){
?? ??? ??? ??? ??? ?try {
?? ??? ??? ??? ??? ??? ?var progress = new FileProgress(file,? this.customSettings.upload_target);

?? ??? ??? ??? ??? ??? ??? ?addFileInfo(file.id,"<span style='color:green;'>上传成功</span>");
?? ??? ??? ??? ??? ??? ??? ?Dialog.alert("提示：上传成功！",function() {
?? ??? ??? ??? ??? ??? ??? ??? ?window.location.href="<%=path %>/courseManage/addCourseware.action?recordeId="+recordeId+"&coursePlanId="+coursePlanId;
?? ??? ??? ??? ??? ??? ??? ?});
?? ??? ??? ??? ??? ??? ?}
?? ??? ??? ??? ??? ? ??? ?if(serverData==1)
?? ??? ??? ??? ??? ??? ??? ?addFileInfo(file.id,"文件上传失败！文件太大");
?? ??? ??? ??? ??? ? ??? ?if(serverData==2)

?? ??? ??? ??? ??? ? ??? ?if(serverData==12)
?? ??? ??? ??? ??? ??? ??? ?addFileInfo(file.id,"文件上传失败！文件太大且类型不对");
?? ??? ??? ??? ??? ? ??? ?if(serverData==3)
?? ??? ??? ??? ??? ??? ??? ?addFileInfo(file.id,"文件上传失败");
?? ??? ??? ??? ??? ?} catch (ex) {
?? ??? ??? ??? ??? ??? ?this.debug(ex);
?? ??? ??? ??? ??? ?}
?? ??? ??? ??? ?},
?? ??? ??? ??? ?upload_complete_handler : uploadComplete,
?? ??? ??? ??? ?// Button Settings

?? ??? ??? ??? ?button_placeholder_id : "spanButtonPlaceholder",
?? ??? ??? ??? ?button_width: 180,
?? ??? ??? ??? ?button_height: 25,
?? ??? ??? ??? ?button_text : '<span class="button"></span>',
?? ??? ??? ??? ?button_text_style : '.button { font-family: Helvetica,Arial,sans-serif; font-size: 12pt; } .buttonSmall { font-size: 10pt; }',
?? ??? ??? ??? ?button_text_top_padding: 0,
?? ??? ??? ??? ?button_text_left_padding: 18,
?? ??? ??? ??? ?button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT,
?? ??? ??? ??? ?button_cursor: SWFUpload.CURSOR.HAND,
?? ??? ??? ??? ?
?? ??? ??? ??? ?// Flash Settings
?? ??? ??? ??? ?flash_url : "<%=path%>/js/swfupload/swfupload.swf",
?? ?
?? ??? ??? ??? ?custom_settings : {
?? ??? ??? ??? ??? ?upload_target : "divFileProgressContainer" //进度框显示的id位置
?? ??? ??? ??? ?},
?? ??? ??? ??? ?// Debug Settings
?? ??? ??? ??? ?debug: false? //是否显示调试窗口
?? ??? ??? ?});

在要上传时，使用

?????????????????? swfu.startUpload(); 进行文件的上传

action：制定的保存文件的action

??? public String saveCourseware(){

?? ?}

保存文件的具体方法：

?? /**
?? ? * 文件上传
?? ? */
?? ?public String fileUpload(Accessory accessory){
?? ??? ?String newFileName = FileUtility.randomFileName(coursewareFileName);?? ?//利用时间随机生成文件名
?? ??? ?String dir=ServletActionContext.getServletContext().getRealPath( "/uploadCourseware") + File.separator;?? ??? ?
?? ??? ?if(accessory.getFileType().equals("1")){
?? ??? ??? ?dir=ServletActionContext.getServletContext().getRealPath( "/applications/vod/media") + File.separator;
?? ??? ?}
?? ??? ?if(accessory.getFileType().equals("4")){
?? ??? ??? ?dir=ServletActionContext.getServletContext().getRealPath( "/applications/vod/media") + File.separator;
?? ??? ??? ?newFileName=newFileName.substring(0,newFileName.lastIndexOf("."));
?? ??? ??? ?try {
?? ??? ??? ??? ?FileUtility.unZipFiles(courseware,dir+newFileName+File.separator,newFileName);? // 解压压缩包
?? ??? ??? ??? ?FileUtility.changeCode(dir+newFileName+File.separator);
?? ??? ??? ??? ?List<String> list=new ArrayList<String>();
?? ??? ??? ??? ?list=FileUtility.getFilePlayTime(dir+newFileName+File.separator,list);
?? ??? ??? ??? ?if(list!=null&&list.size()>0){
?? ??? ??? ??? ??? ?accessory.setPlayTime(Double.valueOf(list.get(0)));
?? ??? ??? ??? ?}else
?? ??? ??? ??? ??? ?accessory.setPlayTime(0.0d);
?? ??? ??? ??? ?
?? ??? ??? ?} catch (IOException e) {
?? ??? ??? ??? ?e.printStackTrace();
?? ??? ??? ?}
?? ??? ?}else{
?? ??? ??? ?File imageFile1 = new File(dir + newFileName);
?? ??? ??? ?FileUtility.copy(courseware,imageFile1);?? ??? ?//保存新上传文件
?? ??? ??? ?if(accessory.getFileType().equals("1")){
?? ??? ??? ?//?? ?accessory.setPlayTime(Double.valueOf(FileUtility.getFilePlayTime(courseware)));?? ?
?? ??? ??? ??? ?accessory.setPlayTime(FileUtility.ffmpeg(dir+newFileName));
?? ??? ??? ?}
?? ??? ?}
?? ??? ?return newFileName;
?? ?}

//产生随机生成的字符串名字;
?? ?public static String randomNameFile(String fileName)
?? ?{
?? ??? ?if(-1 == fileName.lastIndexOf("."))
?? ??? ?{
?? ??? ??? ?return CharacterUtil.randomString(5);
?? ??? ?}
?? ??? ?return CharacterUtil.randomString(5) + fileName.substring(fileName.lastIndexOf("."),fileName.length());
?? ?}
?? ?public static void copy( File src,? File dst) {
?? ??? ?try {
?? ??? ??? ?InputStream in = null;
?? ??? ??? ?OutputStream out = null;
?? ??? ??? ?try {
?? ??? ??? ??? ?// 输入到缓冲流
?? ??? ??? ??? ?in = new BufferedInputStream(new FileInputStream(src),
?? ??? ??? ??? ??? ??? ?BUFFER_SIZE);
?? ??? ??? ??? ?out = new BufferedOutputStream(new FileOutputStream(dst),
?? ??? ??? ??? ??? ??? ?BUFFER_SIZE);
?? ??? ??? ??? ?byte[] buffer = new byte[BUFFER_SIZE];
?? ??? ??? ??? ?int i = 0;
?? ??? ??? ??? ?while ((i = in.read(buffer)) != -1) {
?? ??? ??? ??? ??? ?out.write(buffer,i);
?? ??? ??? ??? ??? ?i = 0;
?? ??? ??? ??? ?}
?? ??? ??? ?} finally {
?? ??? ??? ??? ?if (null != in) {
?? ??? ??? ??? ??? ?in.close();
?? ??? ??? ??? ?}
?? ??? ??? ??? ?if (null != out) {
?? ??? ??? ??? ??? ?out.close();
?? ??? ??? ??? ?}
?? ??? ??? ?}
?? ??? ?} catch (Exception e) {
?? ??? ??? ?e.printStackTrace();
?? ??? ?}
?? ?}

//参数说明

二、各种事件说明

三、swfupload实例的方法

四、文件信息对象 File Object

在事件监听函数中，经常要用到文件信息对象来获取文件的信息以供下一步的操作

五、队列状态对象 Stats Object

用来获取当前队列的状况

六、一些常量

定义的一些常量，便于理解

火狐浏览器问题： session问题

?upload_url: "<%=path%>upload.action;jsessionid=<%=request.getSession().getId()%>",//指向web项目下的名为upload的action
