UplogdDialog+Struts2文件上传.doc

Extjs UploadDialog+Struts2的多文件上传 2012/7/18需要弄清以下几点：1. Extjs控件的实现Ext.ux.UploadDialog.Dialog2. Struts2文件上传机制 主要是配置文件struts.xml applicationContext.xml (此处不涉及数据库的问题，直接上传到服务器)3. 用I/O流对文件进行保存（缓冲流对文件的读写复制）Upload.jsp网站管理 /引用ext包Ext.onReady(function() var dialog = new Ext.ux.UploadDialog.Dialog( title: Upload , id:uploadDialog, url:/file/certFileAction_upload.action, post_var_name:file, width : 450, height : 300, minWidth : 450, minHeight : 300, draggable : true , resizable : true , constraintoviewport: true , modal: true , reset_on_hide: false , allow_close_on_upload: true , /关闭上传窗口是否仍然上传文件 permitted_extensions: xls,xlsx, /upload_autostart: true /是否自动上传文件 upload_autostart: false ); dialog.on( uploadsuccess , onUploadSuccess); /定义上传成功回调函数 dialog.on( uploadfailed , onUploadFailed); /定义上传失败回调函数 dialog.show(););/文件上传成功后的回调函数 onUploadSuccess = function() / alert(上传成功！); ; /文件上传失败后的回调函数 onUploadFailed = function() / alert(上传失败); ; CertFileAction.javapackage com.hisencyber.platform.web.action;import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import javax.servlet.http.HttpServletResponse;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.util.Date;import mons.fileupload.util.Streams;import org.apache.struts2.ServletActionContext;import com.hisencyber.platform.exception.BussinessException;public class CertFileAction public void upload() throws IOException, BussinessException response = ServletActionContext.getResponse(); response.setContentType(text/html;charset=utf-8); /文件上传后存放的路径目录 String fileBasePath = ServletActionContext.getServletContext().getRealPath(/); System.out.println(fileBasePath :+fileBasePath); File fullPath = new File(fileBasePath + /upload/); /设置文件保存路径 if(!fullPath.exists() fullPath.mkdirs(); BufferedInputStream bis = null; BufferedOutputStream bos =null; try for(int i = 0; i file.length; i+) File file1 = filei; System.out.println(fileFileName :+fileFileName); try bis = new BufferedInputStream(new FileInputStream(fi le1); String fileName = new Date().getTime()+.xls; String path=fullPath.getPath()+/+fileName; bos = new BufferedOutputStream(new FileOutputStream (new File(path); Streams.copy(bis, bos, true); System.out.println(上传成功1个！); /每上传成功一个文件都会显示，多文件的上传实际是单个文件的连续上传 catch(Exception e)e.printStackTrace(); response.getWriter().print(success:true,message:上传成功); /java代码中，response返回的字符串是必须的，如果没有写返回，则前面dialog的grid框中总是提示上传错误。因为没有收到success的标识 /读取和写入文件* catch (Exception e)response.setContentType(text/html;charset=utf-8);response.getWriter().print(success:false,message:上传失败);e.printStackTrace(); private File file;private String uploadFileNames;private String uploadContentTypes; /用于封装上传文件的文件名和文件类型private String fileFileName; /上传文件的文件名，可以直接获取private String fileContentType;private HttpServletResponse response ;public File getFile()return file;public void setFile(File file)this.file = file;public String getUploadFileNames()return uploadFileNames;public void setUploadFileNames(String uploadFileNames)this.uploadFileNames = uploadFileNames;public String getUploadContentTypes()return uploadContentTypes;public void setUploadContentTypes(String uploadContentTypes)this.uploadContentTypes = uploadContentTypes;public String getFileFileName() return fileFileName;public void setFileFileName(String fileFileName) this.fileFileName = fileFileName;public Strin
