通過Java組件iText生成PDF報表或合同，完成pdf上傳，預覽，存入數據庫

因業務需要，做了一個通過Java組件iText生成PDF合同，運行成功了，做個記錄，也分享給大家。

首先，我們需要准備好一個有文本域的pdf文件。
1.先用word做出你需要的模板，並保存。

2.通過Adobe Acrobat Pro DC軟件打開：文件---創建---從文件創建PDF---選擇你的word文件並等待一分鍾左右。如果沒有Adobe Acrobat Pro DC軟件，可以去下載(http://www.xue51.com/soft/4070.html#xzdz)。

3.點擊“准備表單”---“開始”---“保存”---“確定”

4.“添加文本域”---依次添加文本域，並修改名字---點擊保存。

此時，pdf文件就已經准備好了。

然后，我們就開始准備代碼了。
代碼參考來源：https://blog.csdn.net/u012377333/article/details/51264122
前提：在pom文件里添加項目需要的依賴：

<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.10</version>
</dependency>
// 設置字體，防止中文亂碼
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itext-asian</artifactId>
<version>5.2.0</version>
</dependency>

1.根據你的pdf中需要填的字段創建實體類-Ticket

package com.ymy.model;/*
@author ymy
@DESCRIPTION ${DESCRIPTION}
@create 2019/4/12
*/

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.創建功能類-PDFTempletTicket

package com.ymy.util;/*
@author ymy
@DESCRIPTION ${DESCRIPTION}
@create 2019/4/12
*/

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);

/*使用中文字體 */
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.測試類-TestTempletTicket

package com.ymy.util;/*
@author ymy
@DESCRIPTION ${DESCRIPTION}
@create 2019/4/12
*/

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("產品一");
ticket.setName("張三");
ticket.setIdCard("411323166517786546");
ticket.setTel("15723546678");
ticket.setAddress("上海市浦東新區");

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，運行成功出來：
