RTFEditorKit rtfParser = new RTFEditorKit();
Document document = rtfParser.createDefaultDocument();
rtfParser.read(new ByteArrayInputStream(rtfBytes), document, 0);
String text = document.getText(0, document.getLength());
this should work
这应该有效
回答by Jens S.
This works if the RTF text is in a JEditorPane
如果 RTF 文本位于 JEditorPane 中，则此方法有效
String s = getPlainText(aJEditorPane.getDocument());
String getPlainText(Document doc) {
try {
return doc.getText(0, doc.getLength());
}
catch (BadLocationException ex) {
System.err.println(ex);
return null;
}
}

I have used it to create a complete RTF editor, with all the supports MS Word has.
我已经用它创建了一个完整的 RTF 编辑器，具有 MS Word 的所有支持。

Apache POI will also read Microsoft Word formats, not just RTF.
Apache POI 还将读取 Microsoft Word 格式，而不仅仅是 RTF。
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;
public String getRtfText(String fileName) {
File rtfFile = null;
WordExtractor rtfExtractor = null ;
try {
rtfFile = new File(fileName);
//A FileInputStream obtains input bytes from a file.
FileInputStream inStream = new FileInputStream(rtfFile.getAbsolutePath());
//A HWPFDocument used to read document file from FileInputStream
HWPFDocument doc=new HWPFDocument(inStream);
rtfExtractor = new WordExtractor(doc);
}
catch(Exception ex)
{
System.out.println(ex.getMessage());
}
//This Array stores each line from the document file.
String [] rtfArray = rtfExtractor.getParagraphText();
String rtfString = "";
for(int i=0; i < rtfArray.length; i++) rtfString += rtfArray[i];
System.out.println(rtfString);
return rtfString;
}
