java根据模板导出PDF（利用itext）
一、制作模板
1.下载Adobe Acrobat 9 Pro软件(pdf编辑器),制作模板必须使用该工具。
2.下载itextpdf-5.5.5.jar、itext-asian-5.2.0.jar两个jar包。（说明：itextpdf-5.5.5.jar用于操作pdf；itext-asian-5.2.0.jar用于pdf中文处理）
3.新建word文档，根据项目需求制作模板，然后另存为pdf格式的文件。
4.Adobe Acrobat 9 Pro软件打开pdf模板文件，点击‘‘表单’’--“启动表单向导”--引入pdf模板文件--添加表单域或者在自动识别的表单域设置表单域名称。设置完成后保存pdf模板。
模板设置如图所示：
最终的模板如下所示：
二、java代码

导出pdf文件如下所示：
此处是main方法测试，如果应用到web项目中可参考下面的代码（与上面的代码几乎一致，加了响应另存为处理，导出pdf就会出现弹框）：
