1、Wf2PdfUtil
此工具类为将流程表单转为pdf的工具类代码,可以根据实际传入参数即可实现将表单转为pdf或html，用于和档案系统集成时较多。

2、测试方法
Wf2PdfUtil wf2PdfUtil = new Wf2PdfUtil();
Map map = wf2PdfUtil.getwfPDF("236236", true, "2");
//map的值={pdf=3251, html=3252}
核对文件，查询数据库
表单存为pdf
html文件
3、引入字体
需要在对应目录下引入字体文件，否则可能导致转出的pdf样式缺失。
如下图怪怪的。

引入字体到对应目录：/weaver/ecology/font/workflow/pdf
