html2pdf 是itext提供的网页转PDF包
老版本的
itextpdf 对html标签转换支持太差，现在升级到最新版本
1，使用版本maven
<dependency> <groupId>com.itextpdf</groupId> <artifactId>html2pdf</artifactId> <version>2.1.5</version> </dependency>
2， 示例
String html="<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/><title>First parse</title></head>" +
"<body style="font-family: SimSun"><div class="t1 pl2" style=" margin: 0; display: flex;flex-wrap: wrap;align-items: center;">
" +
" <div class="ml15" style="display: inline-block;"><input id="ck1" checked="checked" type="checkbox"><label for="ck1">嘟嘟嘟</label></div>
" +
" <div class="ml15" style="display: inline-block;"><input id="ck2" type="checkbox"><label for="ck2">嘿嘿嘿</label></div>
" +
" <div class="ml15" style="display: inline-block;"><input id="ck3" type="checkbox"><label for="ck3">哈哈哈</label></div>
" +
" <div class="ml15" style="display: inline-block;"><input id="ck4" type="checkbox"><label for="ck4">啦啦啦</label></div>
" +
" </div><div><ul>
" +
"<li>Coffee</li>

"<li>Milk</li>
" +
"<li>可以选择</li>

"</ul></div></body></html>";
