通过poi，jar包制作模板动态的生成word文档。支持转换成pdf格式文档

//    用于动态的导出word文档
    // https://mvnrepository.com/artifact/cn.afterturn/easypoi-annotation
    compile group: 'cn.afterturn', name: 'easypoi-annotation', version: '4.2.0'
// https://mvnrepository.com/artifact/cn.afterturn/easypoi-base
    compile group: 'cn.afterturn', name: 'easypoi-base', version: '4.2.0'
// https://mvnrepository.com/artifact/cn.afterturn/easypoi-web
    compile group: 'cn.afterturn', name: 'easypoi-web', version: '4.2.0'
    //用于导出生成pdf
    // https://mvnrepository.com/artifact/com.itextpdf/itextpdf
    compile group: 'com.itextpdf', name: 'itextpdf', version: '5.5.13.2'
//    中文字体
// https://mvnrepository.com/artifact/com.itextpdf/itext-asian
    compile group: 'com.itextpdf', name: 'itext-asian', version: '5.2.0'

使用之前我们先导入poi、jar包

以下为通过模板动态的生成word格式文档

/**

     */
    @RequestMapping(method = RequestMethod.POST, value = "/deriveWord")

        }
        renderResult(response, "word模板生成失败");
    }

生成word转pdf文件

@RequestMapping(method = RequestMethod.POST, value = "/GenerateWordConvertPdf")
    public void GenerateWordConvertPdf(HttpServletRequest request,
                            HttpServletResponse response) throws Exception {
        Map<String, String> data = new HashMap<String, String>();
        try {

            map.put("id", 5);
            map.put("sykt", "test课题");
            ImageEntity img = new ImageEntity("C:\\Users\\Administrator\\Desktop\\tx.jpg", 100, 100);

            ImageEntity img2 = new ImageEntity("C:\\Users\\Administrator\\Desktop\\tx.jpg", 100, 100);

            List<Map<String,Object>> student = new ArrayList();
            Map<String,Object> m = new HashMap();
            m.put("name", "徐江涛");
            m.put("chinese", 88.5);
            m.put("math", 95);
            Map<String,Object> m2 = new HashMap();
            m2.put("name", "考试成绩");
            m2.put("chinese", 82.5);
            m2.put("math", 93);
            student.add(m);
            student.add(m2);
            map.put("student", student);
            XWPFDocument word07 = WordExportUtil.exportWord07("templates/Hello word.docx", map);
            OutputStream outputStream = new FileOutputStream("C:\\Users\\Administrator\\Desktop\\test.docx");
            word07.write(outputStream);
            outputStream.flush();
            outputStream.close();
            PDFUtil.WordConvertPdf("C:\\Users\\Administrator\\Desktop\\test.docx","C:\\Users\\Administrator\\Desktop\\test.pdf");
            renderResult(response, "pdf模板生成成功");
        }
        catch (Exception ex){
            ex.printStackTrace();
        }
        renderResult(response, "pdf模板生成失败");

    }

通过模板生成pdf文件

/**
     * 导出pdf格式报告
     * @param request
     * @param response
     */
    @RequestMapping(method = RequestMethod.POST, value = "/derivePdf")
    public void GeneratePdf(HttpServletRequest request,
                             HttpServletResponse response) throws Exception {
        Map<String, String> data = new HashMap<String, String>();
        try {
            //key为pdf模板的form表单的名字，value为需要填充的值
            data.put("pxsj", "2018-10-8至2020-5-23");
            data.put("xm", "徐江涛");
            data.put("rq", "2020-1-15");
            PDFUtil.generatePDF(pdfTemplatePath,
                    generatePdfPath, data);
            renderResult(response, "pdf模板生成成功");
        }
        catch (Exception ex){
            ex.printStackTrace();
        }
        renderResult(response, "pdf模板生成失败");

    }

word装pdf静态方法和生成pdf文件静态方法如下

/**
     * @param templatePdfPath 模板pdf路径
     * @param generatePdfPath 生成pdf路径
     * @param data            数据
     */
    public static String generatePDF(String templatePdfPath, String generatePdfPath, Map<String, String> data) {
        OutputStream fos = null;
        ByteArrayOutputStream bos = null;
        try {
            File file = new File(generatePdfPath);
            if (file.exists())
            {
                file.delete();
            }
            PdfReader reader = new PdfReader(templatePdfPath);
            bos = new ByteArrayOutputStream();
            /* 将要生成的目标PDF文件名称 */
            PdfStamper ps = new PdfStamper(reader, bos);
            /* 使用中文字体 */
            BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
            ArrayList<BaseFont> fontList = new ArrayList<BaseFont>();
            fontList.add(bf);
            /* 取出报表模板中的所有字段 */
            AcroFields fields = ps.getAcroFields();
            fields.setSubstitutionFonts(fontList);
            fillData(fields, data);
            /* 必须要调用这个，否则文档不会生成的  如果为false那么生成的PDF文件还能编辑，一定要设为true*/
            ps.setFormFlattening(true);
            ps.close();
            fos = new FileOutputStream(generatePdfPath);
            fos.write(bos.toByteArray());
            fos.flush();
            return generatePdfPath;
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (fos != null) {
                try {
                    fos.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (bos != null) {
                try {
                    bos.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return null;
    }

    public static void WordConvertPdf(String sourcePath,String targetPath){
        Document document = new Document();
        document.loadFromFile(sourcePath);

//        //创建一个参数
//        ToPdfParameterList toPdf = new ToPdfParameterList();
//
//        //设置密码
//        String password = "abc123";
//        toPdf.getPdfSecurity().encrypt(password, password, PdfPermissionsFlags.None, PdfEncryptionKeySize.Key_128_Bit);

        //保存文档.
        document.saveToFile(targetPath);

    }
