因业务需要，做了一个通过Java组件iText生成PDF合同，运行成功了，做个记录，也分享给大家。
首先，我们需要准备好一个有文本域的pdf文件。
1.先用word做出你需要的模板，并保存。
2.通过Adobe Acrobat Pro DC软件打开：文件—创建—从文件创建PDF—选择你的word文件并等待一分钟左右。如果没有Adobe Acrobat Pro DC软件，可以去下载（Adobe Acrobat Pro DC破解版下载）。
3.点击“准备表单”—“开始”—“保存”—“确定”
4.“添加文本域”—依次添加文本域，并修改名字—点击保存。
此时，pdf文件就已经准备好了。
然后，我们就开始准备代码了。

前提：在pom文件里添加项目需要的依赖：
<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.10</version></dependency>// 设置字体，防止中文乱码<dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency>
1.根据你的pdf中需要填的字段创建实体类-Ticket
package com.ymy.model;/*@author ymy@DESCRIPTION ${DESCRIPTION}@create /4/12*/public class Ticket {Integer fileId;String productName;String name;String idCard;String tel;String address;public Ticket() {}public Ticket(Integer fileId, String productName, String name, String idCard, String tel, String address) {this.fileId = fileId;this.productName = productName;this.name = name;this.idCard = idCard;this.tel = tel;this.address = address;}public Integer getFileId() {return fileId;}public void setFileId(Integer fileId) {this.fileId = fileId;}public String getProductName() {return productName;}public void setProductName(String productName) {this.productName = productName;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getIdCard() {return idCard;}public void setIdCard(String idCard) {this.idCard = idCard;}public String getTel() {return tel;}public void setTel(String tel) {this.tel = tel;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}}
2.创建功能类-PDFTempletTicket
package com.ymy.util;/*@author ymy@DESCRIPTION ${DESCRIPTION}@create /4/12*/import com.ymy.model.*;import java.io.ByteArrayOutputStream;import java.io.File;import java.io.FileOutputStream;import java.util.ArrayList;import com.itextpdf.text.pdf.AcroFields;import com.itextpdf.text.pdf.BaseFont;import com.itextpdf.text.pdf.PdfReader;import com.itextpdf.text.pdf.PdfStamper;public class PDFTempletTicket {private String templatePdfPath;private String ttcPath;private String targetPdfpath;private Ticket ticket;public PDFTempletTicket() {super();}public PDFTempletTicket(String templatePdfPath, String ttcPath,String targetPdfpath, Ticket ticket) {this.templatePdfPath= templatePdfPath;this.ttcPath= ttcPath;this.targetPdfpath= targetPdfpath;this.ticket= ticket;}public void templetTicket(File file) throws Exception {PdfReader reader = new PdfReader(templatePdfPath);ByteArrayOutputStream bos = new ByteArrayOutputStream();PdfStamper ps = new PdfStamper(reader, bos);/*使用中文字体 */BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);/*BaseFont bf = BaseFont.createFont(PDFTicket.class.getResource("/") + "org/csun/ns/util/simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);*/ArrayList<BaseFont> fontList = new ArrayList<BaseFont>();fontList.add(bf);AcroFields s = ps.getAcroFields();s.setSubstitutionFonts(fontList);s.setField("productName",ticket.getProductName());s.setField("name",ticket.getName());s.setField("idCard",ticket.getIdCard());s.setField("tel",ticket.getTel());s.setField("address",ticket.getAddress());ps.setFormFlattening(false);ps.close();FileOutputStream fos = new FileOutputStream(file);fos.write(bos.toByteArray());fos.close();}/*** @return the templatePdfPath*/public String getTemplatePdfPath() {return templatePdfPath;}/*** @param templatePdfPath the templatePdfPathto set*/public void setTemplatePdfPath(String templatePdfPath) {this.templatePdfPath= templatePdfPath;}/*** @return the ttcPath*/public String getTtcPath() {return ttcPath;}/*** @param ttcPath the ttcPath to set*/public void setTtcPath(String ttcPath) {this.ttcPath= ttcPath;}/*** @return the targetPdfpath*/public String getTargetPdfpath() {return targetPdfpath;}/*** @param targetPdfpath the targetPdfpath toset*/public void setTargetPdfpath(String targetPdfpath) {this.targetPdfpath= targetPdfpath;}/*** @return the ticket*/public Ticket getTicket() {return ticket;}/*** @param ticket the ticket to set*/public void setTicket(Ticket ticket) {this.ticket= ticket;}}
3.测试类-TestTempletTicket
package com.ymy.util;/*@author ymy@DESCRIPTION ${DESCRIPTION}@create /4/12*/import com.ymy.model.Ticket;import java.io.File;public class TestTempletTicket {public static void main(String[] args) throws Exception {Ticket ticket = new Ticket();ticket.setProductName("产品一");ticket.setName("张三");ticket.setIdCard("411323166517786546");ticket.setTel("15723546678");ticket.setAddress("上海市浦东新区");PDFTempletTicket pdfTT = new PDFTempletTicket();pdfTT.setTemplatePdfPath("D:\\file.pdf");//你的pdf模板的位置pdfTT.setTargetPdfpath("D:\\successFile.pdf");pdfTT.setTicket(ticket);File file = new File("D:\\successFile.pdf");file.createNewFile();pdfTT.templetTicket(file);}}
最后，运行成功出来：
