Swing - 当JEditorPane加载本地html时不显示本地图像

我正在写一些加载模板html文档的东西,在其上做一些关键字替换,然后将其打印出来.除了模板中包含图像之外,这种方法很好.如果我浏览模板.html图像显示正常(所以我猜路径没问题),但它们在最终输出中显示为空白区域.

模板html是这样的:

<html>
<body>
<img src="file://c:/temp/my-logo.png" width="50" height="50"/>
[[[some stuff I want to replace]]]
</body>
</html>

很简单.并加载此模板如下:

public void test() {
   JEditorPane text = new JEditorPane("text/html", "default");
   HTMLEditorKit htmlEditorKit = new HTMLEditorKit();
   HTMLDocument htmlDocument = (HTMLDocument)htmlEditorKit.createDefaultDocument();

   text.setEditorKit(htmlEditorKit);
   // read the html template into the JEditorPane's text
   text.read(new BufferedReader(new InputStreamReader(new FileInputStream(new File("path to my template html")))), htmlDocument);

   // then do some replacements
   text.setText(magicReplacements(text.getText()));

   text.repaint();
   // and then print job stuff, fire off the job, check if it worked etc...
}

文本正确显示和格式化,只显示图像.谁能发现什么是错的？

干杯.

我认为这条路是错的.

而不是file://c:/temp/my-logo.png你应该尝试file:/c:/temp/my-logo.png

在测试我的例子时,我使用了两个//c:/和/c:/第二个工作,第一个失败了.

我能够让这个工作......

在此输入图像描述

HTML

<html>
<body>
<img src="file:/c:/backgroundtext.png"/>
[[[some stuff I want to replace]]]
</body>
</html>
