Java用ItextPdf7导出pdf

欢迎各位来我的博客看看

背景

需要导出以下的pdf模板出来，之前做的都用freemarker来导出word，现在更换成了pdf，所以临时整了个

准备工作

maven依赖

 <dependency><groupId>com.itextpdf</groupId><artifactId>itext7-core</artifactId><version>7.1.11</version><type>pom</type></dependency>

api

说到这个itextpdf的api就不得不吐槽下，是写的真不太好

还有各个版本之间差异也有很多，注意自己依赖的版本

大部分都是和html的方法差不多，例如什么margin padding border 都差不多，只是写起来麻烦，无法直观看见效果，需要每次都去生成一遍，再来调整，注意：本人不喜欢写html的东西，所以写出来的效果不是很好，可以有空自己琢磨怎么好看

常用方法

//首先你需要一个writer对象
PdfWriter writer = new PdfWriter(导出路径);
//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
Document document = new Document(pdf, PageSize.A4);
//每次画完一部分的需要用document.add(table)添加到文档对象，才能有效果
//常用的几个实体类
//表格 本文采用的都是表格来布局
Table table = new Table(int列数)
// 单元格 支持合并行 合并列
Cell cell= new Cell(行, 列)
// 段落
new Paragraph(可以直接放文本);//黑色
DeviceRgb black = new DeviceRgb(0, 0, 0);
//灰色
DeviceRgb gray = new DeviceRgb(220, 220, 220);
//灰色虚线边框
DashedBorder grayBorder = new DashedBorder(gray, 0.5F);
//黑色实体边框
SolidBorder solidBorder = new SolidBorder(black, 0.5F);下面的多了一些setWidth setFontSize setFixedLeading setBold setHeight setTextAlignment setVerticalAlignment 这些名词稍微懂点html的都知道啥意思吧，就不需要多介绍了

大致思路

因为要做分页，所以抽了几个方法出来，头部，尾部信息都是一样的，变化的只有中间的商品表格。

所有的布局都是通过table来实现的，有更好的想法可以提出来修改

代码

当一个table 你的列数超过了你设置的值后，就会往下一行排列，这跟html的规则是一样的，注意下

中文字体是需要额外配置的，否则无法显示出来

    /*** 获取中文字体** @return*/private static PdfFont getChineseFont() {try {return PdfFontFactory.createFont("STSongStd-Light", "UniGB-UCS2-H", false);} catch (IOException e) {e.printStackTrace();throw new MyException("获取中文字体失败");}}

头部信息的代码思路就是用的一个table左边单元格是图片,右边的单元格是基本信息，这边的logo暂时是写死路径的，可以自己定义下

 /*** 头部固定位置** @param document* @param pdf* @param type     1.餐厅订单 2.供应商订单* @throws MalformedURLException*/private void drawOrderTop(Document document, PdfDocument pdf, String type) throws MalformedURLException {DeviceRgb black = new DeviceRgb(0, 0, 0);DeviceRgb gray = new DeviceRgb(220, 220, 220);
//        黑色虚线边框DashedBorder grayBorder = new DashedBorder(gray, 0.5F);Table table = new Table(5).setMarginLeft(10).setMarginRight(10);table.setBorder(null);// TODO: 2021/1/8 写死先
//        table.addCell(new Cell().add(new Image(ImageDataFactory.create(configUtil.getStaticUrl() + "/logo.png")).setWidth(25)).setBorder(Border.NO_BORDER));//左边的logo部分table.addCell(new Cell(5, 2).add(new Image(ImageDataFactory.create("E:\\Project\\xxxx\\src\\main\\resources\\static\\img\\logo.png")).setWidth(160)).setBorder(Border.NO_BORDER));//右边的基本信息table.addCell(new Cell(1, 3).setMarginLeft(20).add(new Paragraph("UNITY FRESH SUPPLY SDN. BHD").setFontSize(10).setFontColor(black).setFixedLeading(13).setBold().add(new Text(".(1381196-H)").setFontSize(7))).setWidth(500).setHeight(13).setBorder(null)
//                .setBorderLeft(grayBorder)
//                .setBorderBottom(grayBorder).setTextAlignment(TextAlignment.LEFT));table.addCell(new Cell(1, 3).add(new Paragraph("Address:").setFontSize(7).add(new Text("66, Jalan 5/116b, Kuchai Entrepreneurs Park, ").setFontSize(5))).setHeight(10).setBorder(null)
//                .setBorderLeft(grayBorder)
//                .setBorderBottom(grayBorder).setTextAlignment(TextAlignment.LEFT));table.addCell(new Cell(1, 3).add(new Paragraph().setFontSize(7).add(new Text("58200 Kuala Lumpur, Malaysia.").setFontSize(5))).setHeight(10).setBorder(null)
//                .setBorderLeft(grayBorder)
//                .setBorderBottom(grayBorder).setTextAlignment(TextAlignment.LEFT));table.addCell(new Cell(1, 3).add(new Paragraph("Email:").setFontSize(7).add(new Text("newpower.my@gmail.com").setFontSize(5))).setHeight(10).setBorder(null)
//                .setBorderLeft(grayBorder)
//                .setBorderBottom(grayBorder).setTextAlignment(TextAlignment.LEFT));table.addCell(new Cell(1, 3).add(new Paragraph("TEL:").setFontSize(7).add(new Text("+60 10 280 2037").setFontSize(5))).setHeight(10).setBorder(null)
//                .setBorderLeft(grayBorder)
//                .setBorderBottom(grayBorder).setTextAlignment(TextAlignment.LEFT));if (StringUtils.equals(type, "1")) {table.addCell(new Cell(1, 5).add(new Paragraph("ORDER").setFixedLeading(20)).setFontSize(10).setHeight(20).setBold().setTextAlignment(TextAlignment.RIGHT).setBorder(null));}if (StringUtils.equals(type, "2")) {table.addCell(new Cell(1, 5).add(new Paragraph("PURCHASE ORDER").setFixedLeading(20)).setFontSize(10).setHeight(20).setBold().setTextAlignment(TextAlignment.RIGHT).setBorder(null));}document.add(table);}

基本信息的

思路也是一样的都是table 依次排列出来

/*** @param document* @param billInfo* @param i* @param count* @param type     1.餐厅订单 2.供应商订单*/public void drawOrderBaseInfo(Document document, BillInfoDto billInfo, int i, int count, String type) {DeviceRgb black = new DeviceRgb(0, 0, 0);DeviceRgb gray = new DeviceRgb(220, 220, 220);
//        黑色虚线边框DashedBorder grayBorder = new DashedBorder(gray, 0.5F);SolidBorder solidBorder = new SolidBorder(black, 0.5F);Table table = new Table(6).setMarginLeft(10).setMarginRight(10);table.setBorder(null);table.addCell(new Cell(8, 4).setBorder(null).setMargin(0).setPadding(0).add(new Table(4).setMargin(0).setPadding(0).addCell(new Cell(3, 4).setBorder(null).setWidth(300).setMargin(0).setPadding(0).add(new Table(4).setMargin(0).setPadding(0).setBorder(null).addCell(new Cell(1, 2).setBorder(null).setWidth(228).add(new Paragraph("Bill to:"))).addCell(new Cell(1, 2).setBorder(null).setWidth(200).add(new Paragraph("Delivery Address:"))).addCell(new Cell(1, 2).setBorder(null).add(new Paragraph(billInfo.getBillName()).setFont(getChineseFont()).setFontSize(8).setHeight(20))).addCell(new Cell(1, 2).setBorder(null).add(new Paragraph(billInfo.getDeliveryAddress()).setFontSize(8).setHeight(20))).addCell(new Cell(1, 2).setBorder(null).add(new Paragraph(billInfo.getBillTo()).setFont(getChineseFont()).setFontSize(8).setHeight(20))).addCell(new Cell(1, 2).setBorder(null).add(new Paragraph(billInfo.getArea()).setFont(getChineseFont()).setFontSize(8).setHeight(20))))).addCell(new Cell(1, 4).setBorder(null).setBorder(null).add(new Paragraph("").setHeight(10))).addCell(new Cell(1, 2).setBorder(null).setBorder(null)
//                                                .setBorderRight(solidBorder).add(new Paragraph("Attn:").add(new Text(billInfo.getName()).setFont(getChineseFont()).setFontSize(9)))).addCell(new Cell(1, 2).setPaddingLeft(10).setBorder(null).add(new Paragraph("Attn:").add(new Text(billInfo.getAgent()).setFont(getChineseFont()).setFontSize(9)))).addCell(new Cell(1, 2).setBorder(null).setBorder(null)
//                                                .setBorderRight(solidBorder).add(new Paragraph("TEL:").setFontSize(10).add(new Text(billInfo.getTel()).setFont(getChineseFont()).setFontSize(9)))).addCell(new Cell(1, 2).setBorder(null).setBorder(null).add(new Paragraph("TEL:").setFontSize(10).setPaddingLeft(10).add(new Text(billInfo.getAgentPhone()).setFont(getChineseFont()).setFontSize(9)))).addCell(new Cell(2, 2).setBorder(null).setBorder(null).setHeight(40).add(new Paragraph("Email:").setFontSize(10).add(new Text(billInfo.getEmail()).setFont(getChineseFont()).setFontSize(9)))).addCell(new Cell(2, 2).setBorder(null).setBorder(null).setHeight(40))));if (StringUtils.equals("1", type)) {table.addCell(new Cell(7, 2).setBorder(null).setWidth(160).add(new Table(2).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Order No.:").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getInvoiceNo()).setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Area:").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getArea()).setFontSize(8).setFont(getChineseFont()))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Agent:").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getAgent()).setFontSize(8).setFont(getChineseFont()))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Date : ").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getDate()).setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Terms : ").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Cash").setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Page :").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(i + "/" + count).setFontSize(8))).addCell(new Cell(2, 1).setBorder(null).add(new Paragraph("").setFontSize(9)))));}if (StringUtils.equals("2", type)) {table.addCell(new Cell(7, 2).setBorder(null).setWidth(160).add(new Table(2).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Order No.:").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getInvoiceNo()).setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Area:").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getArea()).setFontSize(8).setFont(getChineseFont()))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Date : ").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(billInfo.getDate()).setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph("Page :").setFontSize(9))).addCell(new Cell(1, 1).setBorder(null).add(new Paragraph(i + "/" + count).setFontSize(8))).addCell(new Cell(2, 1).setBorder(null).add(new Paragraph("").setFontSize(9))).addCell(new Cell(3, 2).setBorder(null).add(new Paragraph("")))));}document.add(table);}

商品表格因为我这边是做了分页效果的，思路也是一样的，先画表头，再循环添加每一条商品信息进去，下面的代码因为分了两个端，所以有两个方法

/*** 餐厅** @param document* @param goods*/public void drawMerchantGoodsInfo(Document document, List<GoodInfoDto> goods) {DeviceRgb black = new DeviceRgb(0, 0, 0);DeviceRgb gray = new DeviceRgb(220, 220, 220);
//        黑色虚线边框DashedBorder grayBorder = new DashedBorder(gray, 0.5F);SolidBorder solidBorder = new SolidBorder(black, 0.5F);Table table = new Table(7).setMarginLeft(10).setMarginRight(10);table.setBorderTop(solidBorder);table.addCell(new Cell(1, 1).setVerticalAlignment(VerticalAlignment.MIDDLE).setTextAlignment(TextAlignment.CENTER).setWidth(50).setBorder(null).setBorderBottom(solidBorder).add(new Paragraph("Item.").setFontSize(8)));table.addCell(new Cell(1, 2).setVerticalAlignment(VerticalAlignment.MIDDLE).setTextAlignment(TextAlignment.CENTER).setWidth(300).setBorder(null).setBorderBottom(solidBorder).add(new Paragraph("Description").setFontSize(8)));table.addCell(new Cell(1, 1).setWidth(70).setVerticalAlignment(VerticalAlignment.MIDDLE).setTextAlignment(TextAlignment.CENTER).setBorder(null).setBorderBottom(solidBorder).add(new Paragraph("Qty").setFontSize(8)));table.addCell(new Cell(1, 2).setWidth(165).setBorder(null).setBorderTop(solidBorder).setBorderBottom(solidBorder).add(new Table(1).setBorder(null).addCell(new Cell(1, 1).setBorder(null).setWidth(87).setTextAlignment(TextAlignment.CENTER).add(new Paragraph("Discounted Price").setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).setTextAlignment(TextAlignment.CENTER).add(new Paragraph("RM").setFontSize(8)))));table.addCell(new Cell(1, 2).setWidth(165).setBorder(null).setBorderTop(solidBorder).setBorderBottom(solidBorder).add(new Table(2).setBorder(null).addCell(new Cell(1, 1).setBorder(null).setWidth(87).setTextAlignment(TextAlignment.CENTER).add(new Paragraph("Unit Price").setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).setWidth(87).setTextAlignment(TextAlignment.CENTER).add(new Paragraph("Amount").setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).setTextAlignment(TextAlignment.CENTER).add(new Paragraph("RM").setFontSize(8))).addCell(new Cell(1, 1).setBorder(null).setTextAlignment(TextAlignment.CENTER).add(new Paragraph("RM").setFontSize(8)))));//        商品for (int i = 0; i < goods.size(); i++) {GoodInfoDto goodInfoDto = goods.get(i);

下面代码还有其他的逻辑，比如说数字金额转为英文的之类的，但是对功能没啥影响，不需要的可以删除
