Java 创建PDF表单域
1、步骤1：在Java程序中新建一个文件夹可命名为Lib。并将产品包中的2个jar文件复制到新建的文件夹下。
2、步骤2：复制文件后，添加到引用类库：选中这两个jar文件，点击鼠标右键，选择“Build Path” – “Add to Build Path”。完成引用。

//添加签名域
page.getCanvas().drawString("本人签字确认\n以上信息属实：", font, brush1, new Point2D.Float(0, baseY));
PdfSignatureField sgnField= new PdfSignatureField(page,"sgnField");//创建sgnField对象
Rectangle2D.Float sgnBounds = new Rectangle2D.Float(baseX, baseY, 150, 80);//创建sgnBounds对象
sgnField.setBounds(sgnBounds);
doc.getForm().getFields().add(sgnField);//添加sgnField到PDF
baseY += 90;
//添加按钮
page.getCanvas().drawString("", font, brush1, new Point2D.Float(0, baseY));
Rectangle2D.Float btnBounds = new Rectangle2D.Float(baseX, baseY, 50, 15);//创建btnBounds对象
PdfButtonField buttonField = new PdfButtonField(page, "Button");//创建buttonField对象
buttonField.setBounds(btnBounds);
buttonField.setText("提交");//设置按钮显示文本
buttonField.setFont(font);
doc.getForm().getFields().add(buttonField);//添加按钮到PDF
//保存文档
doc.saveToFile("result.pdf", FileFormat.PDF);
}
}
2、运行程序后，生成文档。表单域创建效果如下：
