标题java用itextPDF生成PDF文件保存至本地并上传至ftp服务器

所需jar :itext-asian-5.2.0.jar,itextpdf-5.5.5.jar,commons-net-3.3.jar 因为上传不了只能这样了

设置页面上的属性,比如页眉页脚之类的

package com.ibm.business.util;
import java.io.IOException;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;

import com.itextpdf.text.pdf.ColumnText;

import com.itextpdf.text.pdf.PdfWriter;
/import com.sign.system.PathCons;
