java中利用iText实现导入数据到pdf模板中

1,引入jar包

E:/down/java 文档相关操作/iText/iText-5.0.6.jar

E:/down/java 文档相关操作/iText/iTextAsian.jar

2, 利用Excel模板生成pdf文件,Excel单元格格式最好设置成文本，否则pdf填充值时可能中文无法显示

3, 用Acrobat编辑pdf文件，添加新的域，为域设置属性：字体、大小、页面位置...

* 注： 如果有个字段属性设置为：text1,程序中就可以用　s.setField("text1", "aaa一二三");进行符值,参照正文代码

4,代码
