最终生成的PDF预览
itext7的大部分都是和html的方法差不多,如果有前端基础使用起来会很简单。
项目整合itext7(7.1.13)
各个版本之间差异也有很多，注意自己依赖的版本
maven依赖

测试类调用生成PDF文件
public static void main(String[] args) throws FileNotFoundException {
//首先你需要一个writer对象
PdfWriter writer = new PdfWriter("/home/wxy/Desktop/test.pdf");
//需要一个pdf的对象来操作pdf
PdfDocument pdf = new PdfDocument(writer);
//需要一个document的对象来操作数据 指定为A4大小
try (Document document = new Document(pdf, PageSize.A4);) {
drawBaseInfo(document);
} catch (MalformedURLException e) {
throw new RuntimeException(e);
}
}
new Cell(1, 2) 两个参数表示这个单元格纵向占1格,横向占2格
