Epa*_*aga 3 html java swing jeditorpane
我有以下代码:
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.ScrollPaneConstants;
public class ScratchPad {
public static void main(String args[]) throws Exception {
String html ="<html>"+
"<head>"+
"<meta http-equiv=\"Content-Type\" content=\"text/html; charset=ISO-8859-1\"/>"+ // this is the problem right here
"<title>Error 400 BAD_REQUEST</title>"+
"</head>"+
"<body>"+
"<h2>HTTP ERROR: 400</h2><pre>BAD_REQUEST</pre>"+
"<p>RequestURI=null</p>"+
"<p><i><small><a href=\"http://jetty.mortbay.org\">Powered by jetty://</a></small></i></p>"+
"</body>"+
"</html>";
JFrame f = new JFrame();
JEditorPane editor = new JEditorPane();
editor.setEditable( false );
editor.getDocument().putProperty( "Ignore-Charset", "true" ); // this line makes no difference either way
editor.setContentType( "text/html" );
editor.setText( html );
f.add( new JScrollPane(editor, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED,
ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER) );
f.pack();
f.setVisible( true );
}
}
如果你运行它,你会发现框架是空白的.但是,如果我从元标记中删除"; charset = ISO-8859-1",则会显示HTML.任何想法为什么以及我能做些什么来防止这种情况(除了手动黑客攻击我无法控制的HTML字符串...).
编辑#1 - putProperty("Ignore-Charset","true")遗憾地没有任何区别.

使用setText之前和setContentType之后的跟随行.
editor.getDocument().putProperty("IgnoreCharsetDirective", Boolean.TRUE);
这是一个神秘的无证功能.setContentType创建一个新文档,如果之前设置它,它将无效.
