Question

EDITED

我使用<p:uploadfile>将图片上传到我的文章的项目目录中，上传成功，但我无法立即查看图片，但刷新工作区后在我的文章中出现。
UPLOAD方法：

public void upload(FileUploadEvent event) {
    try {
        new FileUpload().copyFile(event.getFile().getFileName(), event
                .getFile().getInputstream());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

COPYFILE方法：

public void copyFile(String fileName, InputStream in) {
        try {

            OutputStream out = new FileOutputStream(new File(destination
                    + fileName));
            int read = 0;
            byte[] bytes = new byte[1024];
            while ((read = in.read(bytes)) != -1) {
                out.write(bytes, 0, read);
            }
            in.close();
            out.flush();
            out.close();
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }
    }
