Ext.onReady(function(){
Ext.QuickTips.init();
dialog = new Ext.ux.UploadDialog.Dialog({
autoCreate: true,
closable: true,
collapsible: false,
draggable: true,
minWidth: 400,
minHeight: 200,

用来中文化

后台代码：
参考贴:http://hi.baidu.com/freespace520/blog/item/d789b40f2a6564226159f308.html#comment
基本上看这个贴子可以做出来后台的代码..出现的问题，该楼主已经有了答复。
public class UploadFileAction extends ActionSupport {
private File file;
private String fileFileName;
private String fileContentType;
public String getFileContentType() {
return fileContentType;
}
public void setFileContentType(String fileContentType) {
this.fileContentType = fileContentType;
}
public String getFileFileName() {
return fileFileName;
}
public void setFileFileName(String fileFileName) {
this.fileFileName = fileFileName;
}
public void setFile(File file) {
this.file = file;
}
public File getFile(){
return file;
}
public String execute(){
System.out.println("begin upload file.... ");
LinkPath link = LinkPath.newInstance();//这是一个存放路径类，直接写个路径就好了，也可以用struts2配置默认路径
String dataPath = link.getdataPath();
DateFormat format = new SimpleDateFormat("yyyyMMddHHmm");
Date date=new Date();
String dateDir = format.format(date);
File f = new File(dataPath+"\"+dateDir);
if(!f.exists()){
f.mkdirs();
}
File dataFile = new File(dataPath+"\"+dateDir+"\"+this.getFileFileName());
try {
//将第一个参数对应的 文件 copy 到 第二个参数对应的文件中
FileUtil.copyFile(this.file,dataFile);
if(dataFile.exists()){
String fileType = dataFile.getPath().substring
(dataFile.getPath().lastIndexOf("."),dataFile.getPath().length());
if(".zip".equals(fileType)||".ZIP".equals(fileType)){
UpZIP zip = new UpZIP();//这是一个压缩类
zip.unzip(dataFile.getPath(), dataPath+"\"+dateDir);
dataFile.delete();
}
}
Struts2Utils.renderText("{success:true,message:'上传成功'}");
} catch (IOException e) {
Struts2Utils.renderText("{success:flase,message:'失败'}");
e.printStackTrace();
}
return null;
}
}
压缩类参考贴：http://www.blogjava.net/dreamstone/archive/2007/08/09/134986.html
当然不要压缩这个功能也没事...
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class Zip {
static final int BUFFER = 2048;
public static void main(String argv[]) {
try {
BufferedInputStream origin = null;
FileOutputStream dest = new FileOutputStream("E:\\test\\myfiles.zip");
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
dest));
byte data[] = new byte[BUFFER];
File f = new File("e:\\test\\a\");
File files[] = f.listFiles();
for (int i = 0; i < files.length; i++) {
FileInputStream fi = new FileInputStream(files[i]);
origin = new BufferedInputStream(fi, BUFFER);
ZipEntry entry = new ZipEntry(files[i].getName());
out.putNextEntry(entry);
int count;
while ((count = origin.read(data, 0, BUFFER)) != -1) {
out.write(data, 0, count);
}
origin.close();
}
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
大体就这样了，struts.xml配置，我基本上没配置多少....
接下来做附件查看和附件删除了...
能上传当然要能删除....累啊
我很菜很菜很菜很菜很菜很菜很菜很菜很菜很菜很菜很菜很菜很菜.......
