Java使⽤itext根据已有的PDF模板进⾏填充并⽣成新PDF 使⽤itext 填充已有的PDF模板⽣成新的PDF
1. POM⽂件添加
<!-- itextpdf 依赖包-->
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.10</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itext-asian</artifactId>
<version>5.2.0</version>
</dependency>
2. 新建PdfUtils⼯具类
import Document;
import pdf.*;
import s.io.FileUtils;
import s.io.IOUtils;
import s.lang3.StringUtils;
import java.io.*;
import java.util.*;
public class PdfUtils {

* @param map 需要填充的字段
* @param sourceFile 原⽂件路径
* @param targetFile ⽬标⽂件路径
* @throws IOException
*/

3. 实现代码
public static void main(String[] args)throws IOException {
//Map中Key对应PDF表单中的fieldNames，Value则是你想填充的值 HashMap map =new HashMap<String, String>();
map.put("name","杨杰");
map.put("xMan","On");//Value为On 则勾选这个复选框
map.put("age","27");
map.put("phone","15521331");
map.put("email","");
String sourceFile ="D:\\proposal.pdf";//原⽂件路径
String targetFile ="D:\\test.pdf";//⽬标⽂件路径
}
