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");
