一、使用Aspose
1、前言：
Aspose可能需要收费，在https://mvnrepository.com/上有可能下载不下来，所以配上Aspose.Pdf的jar包

提取码：1el6
如果想下载源文件可以进行下载
2、创建一个模型
package com.test.model;
/**
* @author
* @Description
* @date
*/
public class PdfAsposeModel {
private Double xCoordinate;
private Double yCoordinate;
private Integer pageNum;
private String content;
public Double getxCoordinate() {
return xCoordinate;
}
public void setxCoordinate(Double xCoordinate) {
this.xCoordinate = xCoordinate;
}
public Double getyCoordinate() {
return yCoordinate;
}
public void setyCoordinate(Double yCoordinate) {
this.yCoordinate = yCoordinate;
}
public Integer getPageNum() {
return pageNum;
}
public void setPageNum(Integer pageNum) {
this.pageNum = pageNum;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public PdfAsposeModel(Double xCoordinate, Double yCoordinate, Integer pageNum, String content) {
this.xCoordinate = xCoordinate;
this.yCoordinate = yCoordinate;
this.pageNum = pageNum;
this.content = content;
}
}
3、demo测试
package com.test.asposeTest;
import com.aspose.pdf.*;
import com.test.model.PdfAsposeModel;
import org.junit.Test;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.UUID;
/**

*/
public class AsposePdfTest2 {
private static final String FONT = "SimSun";
private static final float FONTSIZE = 15;
@Test
public void asposeTest(){
List<PdfAsposeModel> list = new ArrayList<>();
list.add(new PdfAsposeModel(119d,707d,1,"阿里巴巴"));
list.add(new PdfAsposeModel(119d,619d,1,"张三"));
list.add(new PdfAsposeModel(119d,475d,1,"奥利给"));
String filePath = "C:/Users/Dash/Desktop/劳动合同（标准版）.pdf";
try {
pdfSign2(filePath,list);
} catch (IOException e) {
e.printStackTrace();
}
}
public void pdfSign2(String pdfFilePath,List<PdfAsposeModel> list) throws IOException {
//获取路径
int indexOf = pdfFilePath.lastIndexOf("/");
if(indexOf == -1){
indexOf = pdfFilePath.lastIndexOf("\\");
}
int indexOf2 = pdfFilePath.lastIndexOf(".");
String suffix = pdfFilePath.substring(indexOf2);
String url = pdfFilePath.substring(0,indexOf+1);
url = url + UUID.randomUUID().toString() + suffix;
//复制一份文件，因为需要生成一份新的文件，下面方法是在源文件上进行操纵的
FileInputStream inputStream = null;
FileOutputStream outputStream = null;
try {
inputStream = new FileInputStream(pdfFilePath);
outputStream = new FileOutputStream(url);
int hasRead =0;
while((hasRead = inputStream.read()) != -1){
outputStream.write(hasRead);
}
} catch (IOException e) {
e.printStackTrace();
}finally {
inputStream.close();
outputStream.close();
}
for (PdfAsposeModel model : list) {
Double xCoordinate = model.getxCoordinate();
Double yCoordinate = model.getyCoordinate();
String content = model.getContent();
Integer pageNum = model.getPageNum();
if(xCoordinate == null || yCoordinate == null || content == null || "".equals(content) || pageNum == null || pageNum < 1){
continue;
}
//添加内容
Document document=new Document(url);
if (document!=null) {
Page page = document.getPages().get_Item(pageNum);
if (page != null) {
TextParagraph paragraph = new TextParagraph();
paragraph.getFormattingOptions().setWrapMode(
TextFormattingOptions.WordWrapMode.ByWords);
TextState textState = new TextState();
Font pdfFont = FontRepository.findFont(FONT, true);
textState.setFont(pdfFont);
textState.setFontSize(FONTSIZE);
paragraph.appendLine(content, textState);
Position position = new Position(xCoordinate, yCoordinate);
paragraph.setPosition(position);
TextBuilder textBuilder = new TextBuilder(page);
textBuilder.appendParagraph(paragraph);
} else {
System.out.println("页面第：" + pageNum + "页不存在");
}
document.save();
}
}
}
}
二、使用Itext

<version>5.5.12</version>
</dependency>2、创建模型
* itext大致和aspose一样，只不过aspose坐标是Double类型，而Itext是Float类型，所以在此基础上更改一下类型即可
3、测试demo
1）测试方法
@Test
public void pdfTest() throws IOException, DocumentException {
System.out.println("-------------开始时间："+new Date());
List<PdfItextModel> list = new ArrayList<>();
list.add(new PdfItextModel(119f,707f,1,"阿里巴巴"));
list.add(new PdfItextModel(119f,619f,1,"张三"));
list.add(new PdfItextModel(119f,475f,1,"奥利给"));
String filePath = "C:/Users/Dash/Desktop/劳动合同（标准版）.pdf";
PDFDocHelper2.signSinglePsw(filePath,list);
System.out.println("------------结束时间："+new Date());
}2）实现代码
package com.test.itextTest;
import com.itextpdf.text.BaseColor;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Element;
import com.itextpdf.text.pdf.BaseFont;
import com.itextpdf.text.pdf.PdfContentByte;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfStamper;
import com.test.model.PdfItextModel;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
/**
* @Author
* @Date 19:25 2020/3/7
* @Description
*/
public class PDFDocHelper2 {
// 获取基础文字
public static BaseFont getBaseFont() throws DocumentException, IOException {
BaseFont base = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", false);
return base;
}
/**
*
* @param oldPswFilePath 原来的文件地址
* @param list 需要添加的详细信息
* @return
* @throws IOException
* @throws DocumentException
*/
public static String signSinglePsw(String oldPswFilePath, List<PdfItextModel> list) throws IOException, DocumentException {
int lastIndex = oldPswFilePath.lastIndexOf('.');
// 获取文件后缀
String suffix = oldPswFilePath.substring(lastIndex + 1);
// 判断是否为pdf文件
if (!"pdf".equals(suffix.toLowerCase())) {
throw new RuntimeException("Not is PDF file");
}
// 生成新的文件路径
String newPswPath = oldPswFilePath.substring(0, lastIndex) + "-副本." + suffix;
System.out.println("单个psw文件签名生成的新路径：" + newPswPath);
//解析文件
PdfReader reader = new PdfReader(oldPswFilePath);
FileOutputStream fOut = new FileOutputStream(newPswPath);
PdfStamper stp = new PdfStamper(reader, fOut);
// 总页数
System.out.println("PDF总页数：" + reader.getNumberOfPages());
for (PdfItextModel model : list) {
Float xCoordinate = model.getxCoordinate();
Float yCoordinate = model.getyCoordinate();
Integer pageNum = model.getPageNum();
String content = model.getContent();
if(xCoordinate == null || yCoordinate == null ||
pageNum == null || pageNum == 0 || content == null || "".equals(content)){
continue;
}
PdfContentByte pdfContentByte = stp.getOverContent(pageNum);
pdfContentByte.beginText();
// 设置字体及字号
pdfContentByte.setFontAndSize(getBaseFont(), 16);
addDeptReview(xCoordinate,yCoordinate,pdfContentByte, content);
pdfContentByte.endText();
}
stp.close();
// 将输出流关闭
fOut.close();
reader.close();
// 文件读写结束
System.out.println("PSW文件读写完毕");
return newPswPath;
}
/**
* @Author
* @Date 18:48 2020/3/7
* @Description 添加水印
* @param content
* @param keyword
* @param x X轴坐标
* @param y Y轴坐标
*/
private static void addDeptReview(float x,float y,PdfContentByte content, String keyword) {
content.setColorFill(BaseColor.BLACK);
// 设置水印位置和内容
System.out.println("水印内容：" + keyword);
System.out.println("打印位置坐标：" + x + "," + y);
content.showTextAligned(Element.ALIGN_LEFT, keyword, x, y, 0);
}
}三、效果展示
两种效果展示一致，所以都可使用
