1、引入maven
<dependency> <groupId>com.lowagie</groupId> <artifactId>itext</artifactId> <version>2.1.7</version> </dependency> <dependency> <groupId>com.lowagie</groupId> <artifactId>itext-rtf</artifactId> <version>2.1.7</version> </dependency>
2、大致流程
//创建一条文本对象(A4纸张) Document document = new Document(PageSize.A4); //创建一个DOC文档(根据指定的路径) RtfWriter2.getInstance(document, new FileOutputStream(file_url)); //打开文本对象 document.open(); //添加一个简单的段落 document.add(new Paragraph("Hello World!")); //结束编写 document.close();
3、字体
//设置基础字体 -- 宋体 BaseFont bfChinese = BaseFont.createFont("C:/Windows/Fonts/simfang.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); //设置字体 (含有大小、颜色……) Font titleFont = new Font(bfChinese, 14.0F, 1); //字体:宋体 大小:14.0F 加粗 Font contextFont = new Font(bfChinese, 14.0F, 0); //字体:宋体 大小:14.0F 不加粗 Font contextFont_red = new Font(bfChinese, 14.0F, 0, Color.red); //字体:宋体 大小:14.0F 不加粗 字体颜色:红色 Font contextFont_black = new Font(bfChinese, 14.0F, 0, Color.black);//字体:宋体 大小:14.0F 不加粗 字体颜色:黑色 Font headerFooterFont = new Font(bfChinese, 9.0F, 0);//字体:宋体 大小:9.0F 不加粗
4、设置头 和 页码数
全局变量
private static String TECH_INFO = "这里是顶部"; //头部标语 private static String FOOT_INFO = "这里是底部"; //底部标语
头部
Table header = new Table(2); header.setBorder(0); header.setWidth(100.0F); Paragraph address = new Paragraph(TECH_INFO); address.setFont(headerFooterFont); Cell cell01 = new Cell(address); cell01.setBorder(0); header.addCell(cell01); Paragraph date = new Paragraph("生成日期: " + new SimpleDateFormat("yyyy-MM-dd").format(new Date())); date.setAlignment(2); date.setFont(headerFooterFont); cell01 = new Cell(date); cell01.setBorder(0); header.addCell(cell01); document.setHeader(new RtfHeaderFooter(header));
底部(页码数)
Table footer = new Table(2); footer.setBorder(0); footer.setWidth(100.0F); Paragraph company = new Paragraph(FOOT_INFO); company.setFont(headerFooterFont); Cell cell02 = new Cell(company); cell02.setBorder(0); footer.addCell(cell02); Paragraph pageNumber = new Paragraph("第 "); pageNumber.add(new RtfPageNumber()); pageNumber.add(new Chunk(" 页")); pageNumber.setAlignment(2); pageNumber.setFont(headerFooterFont); cell02 = new Cell(pageNumber); cell02.setBorder(0); footer.addCell(cell02); document.setFooter(new RtfHeaderFooter(footer));
5、表格
Table table1 = new Table(4);//创建表格 int width[] = {18,32,18,32};//设置每列宽度比例 table1.setWidths(width);//设置每列宽度比例 table1.setWidth(95);//占页面宽度比例 //第一行 第一个 Cell cell11 = new Cell(new Paragraph("11",contextFont)); cell11.setVerticalAlignment(Element.ALIGN_TOP); //垂直 居上 cell11.setHorizontalAlignment(Element.ALIGN_RIGHT); //水平 居右 cell11.setBorder(0); //第一行 第二个 Cell cell12 = new Cell("12"); cell12.setVerticalAlignment(Element.ALIGN_BOTTOM); //垂直 居下 cell12.setHorizontalAlignment(Element.ALIGN_LEFT); //水平 居左 cell12.setBorder(0); //第一行 第三个 Cell cell13 = new Cell(new Paragraph("13",contextFont)); cell13.setVerticalAlignment(Element.ALIGN_MIDDLE); //垂直 居中 cell13.setHorizontalAlignment(Element.ALIGN_RIGHT); //水平 居右 cell13.setBorder(0); //第一行 第四个 Cell cell14 = new Cell(new Paragraph("14",contextFont)); cell14.setVerticalAlignment(Element.ALIGN_MIDDLE); //垂直 居中 cell14.setHorizontalAlignment(Element.ALIGN_LEFT); //水平 居左 cell14.setBorder(0); table1.addCell(cell11); table1.addCell(cell12); table1.addCell(cell13); table1.addCell(cell14); document.add(table1);
6、插入图片
//图片路径 String URL = "http://www.baidu.com/img/bd_logo1.png"; //创建图片 Image img = null; try { img = Image.getInstance(URL); img.scalePercent(10); } catch (BadElementException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } //内容 Paragraph context = new Paragraph(); context.setAlignment(1); context.setFont(contextFont); if(img == null){ context.add("没有图片"); }else{ context.add(img); } document.add(context);
