zk FileUpload（文件上传）

<button label="上传 Image" upload="true,maxsize=1073741824">
        <attribute name="onUpload"><![CDATA[
            org.zkoss.util.media.Media media = event.getMedia();
            String fileName = "";
            if(media!=null)
                fileName =  media.getName();
            三种流：
            java.io.InputStream ins = new java.io.ByteArrayInputStream(media.getStringData().getBytes());
            java.io.InputStream ins = new java.io.ByteArrayInputStream(media.getByteData());
            java.io.InputStream ins = new java.io.BufferedInputStream(media.getStreamData());

            java.io.File f = new java.io.File("D:\temp\"+fileName);
            if(!f.exists()){
                   f.createNewFile();
             }
            java.io.OutputStream out = new java.io.FileOutputStream(f);
             byte[] buf=new byte[1024];
              int len;
             while((len=ins.read(buf))>0){
             out.write(buf,0,len);
      }
     out.close();
     ins.close();
     alert("上传成功");
        ]]></attribute>
    </button>

 上传按扭监听器写法：

uploadBtn.addEventListener(Events.ON_UPLOAD, new EventListener() {

@Override
public void onEvent(Event event) throws Exception {
// TODO Auto-generated method stub

UploadEvent uploadEvent = (UploadEvent) event;
Media media = uploadEvent.getMedia();
}
});

解决ZK文件上传中文问题：

 第二种写法（zk8.0.0.1）：

<a id="fileUploadA" label="导出文件"></a>

后台：

fileUploadA.addEventListener(Events.ON_CLICK, new EventListener<Event>() {
            @Override
            public void onEvent(Event event) throws Exception {
                Fileupload.get("选择文件", "上传", 2, 1000000, true);
                Executions.getCurrent().getDesktop().setAttribute(
                                    "org.zkoss.zul.Fileupload.target", fileUploadA);
            }
        });
        fileUploadA.addEventListener(Events.ON_UPLOAD, new EventListener<Event>() {
            @Override
            public void onEvent(Event event) throws Exception {
                UploadEvent uploadEvent = (UploadEvent) event;
                alert(uploadEvent.getMedias().length+"");
            }
        });

效果：
