我在数据库中有一个列,其中保存了RTF格式的文本。
使用Java,我如何只获取其纯文本内容?
RTFEditorKit rtfParser = new RTFEditorKit();
Document document = rtfParser.createDefaultDocument();
rtfParser.read(new ByteArrayInputStream(rtfBytes), document, 0);
String text = document.getText(0, document.getLength());
这应该可以工作。
Apache POI 还可以读取 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;
}
如果 RTF 文本在 JEditorPane 中,这个方法可以正常工作。
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;
}
}
