我需要一个用于HTML2RTF的简单转换器,
我尝试运行以下代码....但是此代码示例出现错误

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


我究竟做错了什么?谷歌在这种情况下不是我的朋友,我希望你能帮助我:)

最佳答案

RTF是8位格式,但是您正在将内容发送到Writer,这是“用于写入字符流的类”。尝试采用write()ByteArrayOutputStream变体:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
…
rtfEditorKit.write(baos, htmlDoc, 0, htmlDoc.getLength());
…
System.out.println(baos.toString());


安慰:

{\ rtf1 \ ansi
{\ fonttbl \ f0 \ fnil等距;}

\ par
