java自生pdf代码多种实现

import com.itextpdf.text.Document; import com.itextpdf.text.DocumentException; import com.itextpdf.text.Paragraph; import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileOutputStream; import java.io.IOException;

public class ItextPdfGenerator { public static void main(String[] args) { // 创建文档对象 Document document = new Document();

try {
        // 创建PdfWriter实例，将文档写入指定文件
        PdfWriter.getInstance(document, new FileOutputStream("itext_example.pdf"));
        
        // 打开文档
        document.open();
        
        // 向文档添加内容
        document.add(new Paragraph("Hello, this is a PDF generated by iText!"));
        document.add(new Paragraph("This is another line in the PDF document."));
        
        // 添加空白行
        document.add(new Paragraph(" "));
        
        // 添加带样式的文本
        Paragraph styledParagraph = new Paragraph("This is a styled paragraph.");
        styledParagraph.setAlignment(Paragraph.ALIGN_CENTER);
        document.add(styledParagraph);
        
        System.out.println("PDF created successfully!");
        
    } catch (DocumentException | IOException e) {
        e.printStackTrace();
    } finally {
        // 关闭文档
        document.close();
    }
}
