7.pom.xml文件：

  <dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itextpdf</artifactId>
            <version>5.4.3</version>
        </dependency>

8.工具类文件：

 public void instanceEnded() throws Exception {
        super.instanceEnded();
        Map params = po.getParameters();
        BtMettingsBeforeLogic logic = new BtMettingsBeforeLogic(dbc);
        Map data = logic.view(params);
        // 生成pdf并上传
        //http://localhost:8086/mss_cw/core/system/control/CommonDownload.jsp?groupId=pdfId 访问路径
        if(null != data){
            byte[] bytes = new BtMettingsBeforePDFLogic(dbc).getPdfBytes(data, "btmeetingsbefore_template.pdf");
         
        }
    }
