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:
