springBoot基於itext實現pdf打印

pom：

控制器Controller

 @RequestMapping(value = "/purchase/order/print", method = RequestMethod.GET)
    public ModelAndView printInvoice(@RequestParam Long id) throws IOException {
        List<Map> list = purchaseOrderService.getList(id);
        Map<String, Object> model = new HashMap<>();
        model.put("sheet", list);
        model.put("row", 8);
        String[] title = new String[]{
                "商品條碼","商品名稱", "規格/單位", "進價/元", "折扣", "採購數量",
                "進貨金額/元"
        };
        model.put("titles", title);
        return new ModelAndView(new ViewPDF(), model);

ViewPDF文件：

/**
 * @作者:huangliang
 * @時間:2020-03-16 15:35
 * @註釋:ViewPDF
 */
public class ViewPDF extends AbstractPdfView {
    @Override
    protected void buildPdfDocument(Map<String, Object> model, Document document, PdfWriter writer, HttpServletRequest request, HttpServletResponse response) throws Exception {
        String fileName = new java.util.Date().getTime() + "_order.pdf";
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/pdf");
        response.setHeader("Content-Disposition", "filename=" + new String(fileName.getBytes(), "iso8859-1"));
        List<Map> products = (List<Map>) model.get("sheet");
        PdfUtil pdfUtil = new PdfUtil();
        int row = (int) model.get("row");
        String[] title = (String[]) model.get("titles");
        pdfUtil.createPDF(document, writer, products, row,title);
    }
}

如果不想要這種直接在瀏覽器中預覽的效果，而是直接下載文件的話就把response.setHeader()方法裏面的參數改成下面的，相當於加了一個attachment，以附件形式下載

response.setHeader("Content-Disposition","attachment;filename=" + new String(fileName.getBytes(), "iso8859-1"));

PdfUtil類：
