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类似于:
<html>
<body>
<img src="file://c:/temp/my-logo.png" width="50" height="50"/>
[[[some stuff I want to replace]]]
</body>
</html>
足够简单。 并加载此模板:
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。

我认为路径是错误的。
而不是file://c:/temp/my-logo.png
,您应该尝试file:/c:/temp/my-logo.png
在测试我的示例时,我使用了//c:/
和/c:/
,第二个使用了,第一个失败了。
我能够让这个工作......

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