Java实现HTML代码生成PDF文档
本文来自CSDN博客，转载请标明出处/zdtwyjp/archive//07/27/5769353.aspx
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：/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！

（二）Flying Sauser
项目主页：https://xhtmlrenderer./依赖jar包：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/blog/611561下载一个jar包，该包对源代码做了稍加修改.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！
