There is also a project for creating PDF files - iText.
There are two sub-projects below PDFBox: FontBox is a java class library that processes PDF fonts; JempBox is a java class library that processes XMP metadata.
A simple example:
To introduce the pdfbox-app-1.6.0.jar package.
The code copy is as follows:
package pdf;
import java.io.File;
import java.net.MalformedURLException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFTextStripper;
public class StripPDFContent {
public static String getText(File file)throws Exception{
boolean sort=false;
int startPage=1;
int endPage=10;
PDDocument document=null;
try{
try{
document=PDDocument.load(file);
}catch(MalformedURLException e){
}
PDFTextStripper stripper=new PDFTextStripper();
stripper.setSortByPosition(sort);
stripper.setStartPage(startPage);
stripper.setEndPage(endPage);
return stripper.getText(document);
}catch(Exception e){
e.printStackTrace();
return "";
} finally{
if(document!=null){
document.close();
}
}
}
public static void main(String[] args){
File file=new File("/home/orisun/123.pdf");
try{
String cont=getText(file);
System.out.println(cont);
}catch(Exception e){
System.out.println("Strip failed.");
e.printStackTrace();
}
}
}
