新手入门

1.maven pom.xml添加依赖:

<groupId>com.itextpdf</groupId>

<artifactId>itextpdf</artifactId>

</dependency>

2.利用adobe acrobat编辑好模板，当然福昕编辑器，迅捷pdf编辑器也是可以的。

先用word编辑好你要生成好的pdf的样式，另存为pdf，再用pdf编辑器设置文本域，保存。

3.Java代码：

把模板拷到resouces下，

从：c/system/fonts/DENG.TTF拷到resources/fonts/目录下。先找到等线，点击进去，复制《等线常规》这个字体。等线常规就是DENG.TTF
