我需要一个简单的 HTML2RTF 转换器 我尝试运行以下代码...但我收到此代码示例的错误
代码:
import java.io.ByteArrayInputStream;
import java.io.StringWriter;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import javax.swing.text.Document;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.rtf.RTFEditorKit;
public class converter {
private static Pattern htmlTrimPattern = Pattern.compile(".*<body>(.*)</body>.*", Pattern.DOTALL);
public static void main(String[] args)
{
toRtf("<!DOCTYPE html>\n" +
"<html>\n" +
"<body>\n" +
"\n" +
"<h1>My First Heading</h1>\n" +
"\n" +
"<p>My first paragraph.</p>\n" +
"\n" +
"</body>\n" +
"</html>\n");
}
public static String toRtf(String html) {
ByteArrayInputStream input= new ByteArrayInputStream(html.getBytes());
StringWriter writer = new StringWriter();
try {
RTFEditorKit rtfEditorKit = new RTFEditorKit();
HTMLEditorKit htmlEditorKit = new HTMLEditorKit();
Document htmlDoc = htmlEditorKit.createDefaultDocument();
htmlEditorKit.read(input, htmlDoc, 0);
rtfEditorKit.write(writer, htmlDoc, 0, htmlDoc.getLength());
} catch (Exception ex) {
System.out.println("Error"+ex);
}
System.out.println(writer.toString());
return writer.toString();
}
}
错误:
Errorjava.io.IOException: RTF is an 8-bit format
我做错了什么？在这种情况下，谷歌不是我的 friend ，我希望你能帮助我:)
最佳答案
RTF是一种 8 位格式，但您要将内容发送到 Writer，这是一个“用于写入字符流的类”。尝试采用 ByteArrayOutputStream 的 write() 变体:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
…
rtfEditorKit.write(baos, htmlDoc, 0, htmlDoc.getLength());
…
System.out.println(baos.toString());
控制台:
{\rtf1\ansi
{\fonttbl\f0\fnil Monospaced;}
\par
My First HeadingMy first paragraph.\par
}
关于javax.swing.text.rtf.RTFEditorKit/RTF 是一种 8 位格式，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19188447/
