Java如何在iText中创建锚点或链接？
本示例向您展示如何使用com.itextpdf.text.Anchor该类在PDF文档中创建外部链接。您可以创建一个Anchor带有字符串短语的实例，并通过调用setReference()此对象的方法来设置其引用（在本例中为网站URL）。
package org.nhooo.example.itextpdf;
import com.itextpdf.text.Anchor;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class AnchorDemo {
public static void main(String[] args) {
Document doc = new Document();
try {
PdfWriter.getInstance(doc, new FileOutputStream("AnchorDemo.pdf"));
doc.open();
String content = "You can learn Java programming on the " +
"following website: ";
Paragraph paragraph = new Paragraph(content);
//创建一个链接到外部网站的新锚点
//并将此锚点添加到段落中。
Anchor anchor = new Anchor("Learn Java by Examples");
anchor.setReference("https://nhooo.org");
paragraph.add(anchor);
doc.add(paragraph);
} catch (DocumentException | FileNotFoundException e) {
e.printStackTrace();
} finally {
doc.close();
}
}
