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
官网：http://www.itextpdf.com/
测试案例：TestIText.java
依赖jar包：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！
