SpringBoot加itext實現PDF導出下載

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/89475877

實現

1.設置響應格式

?response.setContentType("application/pdf");response.setHeader("Expires", "0");response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");response.setHeader("Pragma", "public");

2.設置紙張規格并創建文檔實例

//設置紙張規格為A4紙 Rectangle rect = new Rectangle(PageSize.A4); //創建文檔實例 Document doc=new Document(rect);

3.添加中文字體

BaseFont bfChinese=BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);

4.設置字體樣式

Font textFont = new Font(bfChinese,11, Font.NORMAL); //正常 //Font redTextFont = new Font(bfChinese,11,Font.NORMAL,Color.RED); //正常,紅色 Font boldFont = new Font(bfChinese,11,Font.BOLD); //加粗 //Font redBoldFont = new Font(bfChinese,11,Font.BOLD,Color.RED); //加粗,紅色 Font firsetTitleFont = new Font(bfChinese,22,Font.BOLD); //一級標題 Font secondTitleFont = new Font(bfChinese,15,Font.BOLD, CMYKColor.BLUE); //二級標題 Font underlineFont = new Font(bfChinese,11,Font.UNDERLINE); //下劃線斜體

5.設置字體

com.itextpdf.text.Font FontChinese24 = new com.itextpdf.text.Font(bfChinese, 24, com.itextpdf.text.Font.BOLD);com.itextpdf.text.Font FontChinese18 = new com.itextpdf.text.Font(bfChinese, 18, com.itextpdf.text.Font.BOLD);com.itextpdf.text.Font FontChinese16 = new com.itextpdf.text.Font(bfChinese, 16, com.itextpdf.text.Font.BOLD);com.itextpdf.text.Font FontChinese12 = new com.itextpdf.text.Font(bfChinese, 12, com.itextpdf.text.Font.NORMAL);com.itextpdf.text.Font FontChinese11Bold = new com.itextpdf.text.Font(bfChinese, 11, com.itextpdf.text.Font.BOLD);com.itextpdf.text.Font FontChinese11 = new com.itextpdf.text.Font(bfChinese, 11, com.itextpdf.text.Font.ITALIC);com.itextpdf.text.Font FontChinese11Normal = new com.itextpdf.text.Font(bfChinese, 11, com.itextpdf.text.Font.NORMAL);

6.設置要到處PDF響應并設置導出PDF標題

?

String title = "霸道流氓氣質";response.setHeader("Content-disposition","attachment; filename=".concat(String.valueOf(URLEncoder.encode(title + ".pdf", "UTF-8"))));

7.輸出流轉換

OutputStream out = response.getOutputStream(); PdfWriter.getInstance(doc,out); doc.open(); doc.newPage();

8.新建段落

Paragraph?? p1 = new Paragraph("二級標題", secondTitleFont);

9.設置段落行高

?p1.setLeading(0);

10.設置段落文本居中

?p1.setAlignment(Element.ALIGN_CENTER);

11.將段落添加到文檔上

?doc.add(p1);

12.設置空行

Paragraph blankRow1 = new Paragraph(18f, " ", FontChinese11); doc.add(blankRow1);

13.新建表格列數為2

?PdfPTable table1 = new PdfPTable(2);

14.給表格設置寬度

int width1[] = {80,60}; table1.setWidths(width1);

15.新建單元格并賦值加設置字體

PdfPCell cell11 = new PdfPCell(new Paragraph("姓名：? "+name,boldFont));

16.設置單元格邊框

cell11.setBorder(0);

17.表格中添加單元格

table1.addCell(cell11);

18.關閉文檔

doc.close();
