最近有个任务是动态的创建pdf根据获取到的内容，百度到的知识点都比较零散，官方文档想必大家也不容易看懂。下文是我做出的汇总``

public class CreatePdfUtils {public static void create(){//准备File file = new File("C:\\code\\base-project-backend\\pdf\\"+"1.pdf");Document document = new Document();PdfWriter.getInstance(document,new FileOutputStream(file));document.open();document.setPageSize(PageSize.A4);        //这是第一页的尺寸大小document.add(new Paragraph("hello"));        //这是第一页的内容Rectangle rectangle = new Rectangle(1111, 1111); //这是第二页的尺寸大小rectangle.setBackgroundColor(new BaseColor(11,11,11));//这是第二页的背景颜色document.setPageSize(rectangle); //在这里设置第二页document.newPage();    //这里是真正创建第二页document.add(new Paragraph("wordld"));//第二页增加内容//结束document.close();}
}

接下来还会继续完善

 public static void createPdf(){File file = new File("C:\\code\\base-project-backend\\shiting-module-system\\shiting-module-system-biz\\src\\main\\java\\com\\shiting\\basic\\module\\system\\controller\\admin\\pdf1.pdf");Document document = new
