html转化成PDF

1. jar 包准备

	 core-renderer.jar
	 httpmime-4.5.jar
	 itext-2.0.8.jar
	 itextpdf-5.0.6.jar
	 zxing-core.jar

2. 字体准备

	arialuni.ttf
	msyh.ttc
	msyhbd.ttc
	simfang.ttf
	simhei.ttf
	simsun.ttf

4. 上代码

 @RequestMapping(value = "/xyxx/reportFileGenerate.jspx", method = RequestMethod.GET)
    @ResponseBody
    public RestResult reportFileGenerate1(String id, String code, String name, HttpServletRequest request, HttpServletResponse response, @RequestParam Map<String, Object> parameterMap, ModelMap model) throws Exception {
        String tempPath = Global.getConfig("temp.path");
        //报告下载数量（需要查询业务,此处我随便写的）
        int reportDownloadCount = 10;
        Date nowDate = new Date();
        //报告编号
        String reportNum = DateUtils.formatDate(nowDate, "yyyyMMddHHmmss") + String.format("%06d", reportDownloadCount + 1);
        //报告水印背景的字
        String waterText = "我是报告";
        File dfile = new File(tempPath);
        if (!dfile.exists()) {
            dfile.mkdirs();
        }
        //报告生成存放得临时本地目录
        String path = tempPath + "/" + reportNum + "_1.pdf";
        String path_sy = tempPath + "/" + reportNum + ".pdf";
        File file = null;
        Map<String, String> map = new HashMap<>();

        //begain

        map.put("siteUrl", "www.xxxx.com");
        map.put("reportNum", reportNum);
        map.put("downloadTime", DateUtils.formatDate(nowDate, "yyyy年MM月dd日 HH:mm:ss"));
        //end
        //生成报告
        genPerviewReport(id, code, name, "L", reportNum, "/xyxx/creditReport.jspx", path, path_sy, request, waterText, map);
        file = new File(path_sy); //要下载的文件绝对路径
        String filePath="";
        if (file.exists()) {
            //此处我把报告上传到文件服务器去（根据自己实际情况）
            filePath = FileUpLoadUtils.uploadFileAndGetPath("creditReport", file, reportNum);

        reportDownloadRecord.setSiteName("站点1");
        reportDownloadRecord.setCode(reportNum);
        insertReportDownload(reportDownloadRecord);
        //生成后把报告编号信息返回前端 （原则上只要能返回可以查到报告的数据即可）
        return RestResult.success().setData(reportNum);
    }
