如何使用iText将HTML转换为PDF

jsp

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import com.itextpdf.text.Document;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;

public class GeneratePDF {
    public static void main(String[] args) {
        try {

            String k = "<html><body> This is my Project </body></html>";

            OutputStream file = new FileOutputStream(new File("E:\\Test.pdf"));

            Document document = new Document();
            PdfWriter.getInstance(document, file);

            document.open();

            document.add(new Paragraph(k));

            document.close();
            file.close();

        } catch (Exception e) {

            e.printStackTrace();
        }
    }
}

这是我将HTML转换为PDF的代码。我可以转换它，但是在PDF文件中，它只保存为整个HTML，而我只需要显示文本即可。<html><body> This is my Project </body></html>被保存为PDF而只保存This is my Project。

您可以使用以下HTMLWorker类（不建议使用）来实现：

import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter.getInstance(document, file);
    document.open();
    HTMLWorker htmlWorker = new HTMLWorker(document);
    htmlWorker.parse(new StringReader(k));
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

或使用XMLWorker，（从此jar下载）使用以下代码：

import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(k.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}
