Wicket动态资源显示在HTML中 [英] Wicket Dynamic Resource Displayed in HTML

问题描述

我有一个Wicket页面，它将动态显示图像。假设图像是当前的日期/时间。

I have a Wicket page which will dynamically display an image. Let's say the image is the current date/time.

在HTML中，我会有一些像

In HTML, I would have something like

<img src="[dynamically generated]"/>

假设我有一个实用程序方法，返回给我当前图像的byte []。 p>

Assume I have a utility method which returns to me a byte[] of the current image.

public byte[] getCurrImage();

如何在Wicket（HTML / Java）中实现此动态资源？我无法挂载共享资源，因为图像将始终保持不变。我需要保存图像吗？

How do I implement this dynamic resource in Wicket (HTML/Java)? I can't mount a shared resource because the image will keep changing all the time. Do I need to save the image somewhere?

谢谢

推荐答案

查看 JFreeChart和检票口示例。
您将看到一个派生自 Image 的类的示例，它将获取 byte [] 动态创建像您所问的图像。

Checkout JFreeChart and wicket example. There you will see an example of a class that derives from Image and it gets a byte[] to dynamically create an image like you asked.
