1. 生成pdf 文件  

pdf 文件代码

            }
            try {

                document.close();
                if (logger.isDebugEnabled()) {
                    logger.debug("PDF create filepath : " + file.getAbsolutePath());
                }
                int format = ConversionUtil.toInt(way);
                if (file.exists()) {
                    data.put(PRINTER_CODE, 200);//目前生成pdf,打印失败也算处置成功
                }

                if (printAction(data, file, format)) {
                    data.put(PRINTER_CODE, 200);
                    if (logger.isDebugEnabled()) {
                        logger.debug(filepath + "File printed successfully");
                    }
                } else {
                    data.put(PRINTER_CODE, 500);
                }
            } catch (Throwable e) {
                logger.error("create PDF file failed", e);
            }
        }
        return data;
