e.printStackTrace();
} catch (Exception e) {

}
3.html页面
注意：html格式非常严格，图片地址这里用的是绝对路径(file:///D:/WorkSpace/IdeaProjects/pdf/src/main/resources/static/images/1.jpg)
如果是相对路径要在后台设置
Title
/*没有background-color生产的pdf会是空白*/
body{ text-align:center;border: 0px;margin: 0px;background-color:#FFFFFF;}
.div{ margin:0 auto; width:1188px; height:auto;}
body {
/*中文支持*/
font-family:SimSun;
}

4.生成pdf
超出页面长度时会自动分页
