1.把html转pdf，首先必须要解决中文显示问题，CSS样式问题以及可能的JS问题，先上例子，自己去体会。
2.先去下载simsun.ttc字体；
2.demo.html
<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"/> ???<title>Title</title> ???<style> ???????.color { ???????????color: green; ???????} ???????.pos { ???????????position: absolute; ???????????left: 200px; ???????????top: 5px; ???????????width: 200px; ???????????font-size: 10px; ???????} ???</style></head><body style="font-family: SimSun"> ???<img src="logo.png" width="600px" /> ???<div class="color pos"> ???????hello,${name}; ???</div></body></html>3.java实现转换代码
