谁能告诉我如何将 html 文档加载到 JEditorPane 中。我已经尝试过以下似乎不起作用：
try{
URL h = new URL("file://test.html");
pane.setPage(h);
} catch (Exception e) {}
在java中的jeditor窗格中打开html文件
JeditorPane editorpane= new JEditorPane();
editorScrollPane = new JScrollPane(editorpane);
editorScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
File file = new File("F://test.htm");
editorpane.setPage(file.toURI().toURL());
editorpane.setEditable(true);
希望这对您有帮助， 这是工作
使用绝对路径怎么样？查看 java.lang.System.getProperties 并使用“user.dir”，即获取一些绝对路径来增强文件 url。
您可以按照sun关于swing的webview教程的教程...:) http://docs.oracle.com/javafx/2/swing/SimpleSwingBrowser.java.htm

如何使用 .jar 文件之外的本地文件 setPage() JEditorPane？
// get location of the code source
URL url = yourpackage.Main.class.getProtectionDomain().getCodeSource().getLocation();
try {
// extract directory from code source url
String root = (new File(url.toURI())).getParentFile().getPath();
File doc = new File(root, "test.htm");
// create htm file contents for testing
FileWriter writer = new FileWriter(doc);
writer.write("<h1>Test</h1>");
writer.close();
// open it in the editor
editor.setPage(doc.toURI().toURL());
} catch (Exception e) {
e.printStackTrace();
}
