前台实现：

ExtJS MVC 上传文件button响应事件里面的:

//multi file upload  插件var panel = Ext.create('Ext.ux.uploadPanel.UploadPanel', {header : false,addFileBtnText : '选择日志文件...',uploadBtnText : '上传',removeBtnText : '移除所有',cancelBtnText : '取消上传',file_size_limit : 100,// MBwidth : 750,height : 300,flash_url : "swfupload/swfupload.swf",flash9_url : "swfupload/swfupload_fp9.swf",upload_url : path + '/projectmanager/UploadAction.action'});win = Ext.widget('window', {title : '日志文件上传',closeAction : 'destroy',layout : 'fit',resizable : false,modal : true,items : panel});win.show();

后台实现action：

public class UploadAction  extends Struts2ActionSupport {    private File   Filedata;    private String FiledataFileName;    private String FiledataContentType;    //前台用户修改后的文件名    private String newFileName;        private String savePath;    public String getSavePath() {return savePath;}public void setSavePath(String savePath) {this.savePath = savePath;}public File getFiledata() {return Filedata;}public String getFiledataFileName() {return FiledataFileName;}public String getFiledataContentType() {return FiledataContentType;}public void setFiledata(File filedata) {Filedata = filedata;}public void setFiledataFileName(String filedataFileName) {FiledataFileName = filedataFileName;}public void setFiledataContentType(String filedataContentType) {FiledataContentType = filedataContentType;}//文件读取和日志数据插入到数据库public String fileUpLoad() throws Exception{InputStream  is = new FileInputStream(Filedata);String root = ServletActionContext.getServletContext().getRealPath(savePath); File deskFile = new File(root,newFileName);OutputStream os = new FileOutputStream(deskFile);byte[] buffer = new byte[1024];int length = 0;while((length =is.read(buffer))!=-1){os.write(buffer,0,length);}os.close();is.close();HttpServletResponse response = ServletActionContext.getResponse();response.setCharacterEncoding("UTF-8");response.setContentType("text/xml;charset=utf-8");response.getWriter().write("{success:true}");return null;}public String getNewFileName() {return newFileName;}public void setNewFileName(String newFileName) {this.newFileName = newFileName;}}
