方法1：
import org.apache.tika.Tika;
import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.Parser;
import org.apache.tika.sax.BodyContentHandler;
import org.xml.sax.ContentHandler;
import org.xml.sax.SAXException;
public String fileToTxt(File f){
InputStream is=null;
try
{
Parser parser=new AutoDetectParser();
is=new FileInputStream(f);
ContentHandler handler=new BodyContentHandler();
ParseContext context=new ParseContext();
context.set(Parser.class, parser);
parser.parse(is, handler, new Metadata(), context);
for(String name:metadata.names()){
System.out.println(name+":"+metadata.get(name));
}
return handler.toString();
}
IndexUtil util=new IndexUtil();
System.out.println(util.fileToTxt(new File("d:/1.doc")));
2.2 方法2:
public String tikaTool(File f){
Tika tika=new Tika();
try
{
return tika.parseToString(f);
}
catch (IOException e)
{
e.printStackTrace();
}
catch (TikaException e)
{
e.printStackTrace();
}
return null;
}
这个方法很简单。 直接就可以返回文本内容。
