1、IText实现html2pdf,速度快,纠错能力差,支持中文(要求HTML使用unicode编码),但中支持一种中文字体,开源。
2、Flying Sauser实现html2pdf,纠错能力差,支持多种中文字体(部分样式不能识别),开源。
3、PD4ML实现html2pdf,速度快,纠错能力强,支持多种中文字体,商业。
(一)IText
测试案例:TestIText.java
依赖jar包下载 :iText-2.0.8.jar、iTextAsian.jar(支持中文)
下面只是一个小的测试案例,如果项目中使用到了该组件可以参考API完成项目组中相应的功能!

Paragraph t = new Paragraph(htmlCode, FontChinese);
doc.add(t);
doc.close();
System.out.println("文档创建成功");
}catch(Exception e) {
e.printStackTrace();
}
}
}
(二)Flying Sauser
依赖jar包下载 :iText-2.0.8.jar、iTextAsian.jar、core-renderer.jar
默认情况下,core-renderer.jar对中文是不能进行换行的,如果想解决换行问题可以去下载一个jar包,该包对源代码做了稍加修改.
