利用itext工具编辑生成pdf

1.先用word做出界面

2、把word文档转换成pdf输出

3.用Adobe Acrobat 打开你刚刚用word转换成的pdf，选择“创建PDF表单”

4、选择刚刚生成的pdf

5、打开后它会自动侦测并命名表单域，右键表单域，点击属性，出现文本域属性对话框，（如果没有自动表单域选择工具栏中的添加文本域重新添加）我在使用过程中发现默认的表单域并不能让文字显示，必须手动重新添加文本域，名称可以重新命名

6、修改所有的文本域完成后 保存pdf。接下来就是撸代码了

我用到的jar包有三个如下

<dependency>
        <groupId>com.itextpdf</groupId>
        <artifactId>itextpdf</artifactId>
        <version>5.5.8</version>
    </dependency>
    <dependency>
        <groupId>com.itextpdf.tool</groupId>
        <artifactId>xmlworker</artifactId>
        <version>5.5.8</version>
    </dependency>
    <dependency>
        <groupId>com.itextpdf</groupId>
        <artifactId>itext-asian</artifactId>
        <version>5.2.0</version>
    </dependency>

java代码如下 //利用模板生成pdf
        public void fillTemplate(){
            //模板路径
            String templatePath = "../template_demo.pdf";
            //生成的新文件路径
            String newPDFPath = "../newPdf.pdf";
            PdfReader reader;
            FileOutputStream out;
            ByteArrayOutputStream bos;
            PdfStamper stamper;
            try {
                out = new FileOutputStream(newPDFPath);//输出流
                reader = new PdfReader(templatePath);//读取pdf模板
                bos = new ByteArrayOutputStream();
                stamper = new PdfStamper(reader, bos);
                AcroFields form = stamper.getAcroFields();
    
                String[] str = {"123456789","小鲁","男","1994-00-00","130222111133338888","河北省唐山市"};
                int i = 0;
                //解决中文不显示的问题 注意需要引入itext-asian.jar包
                BaseFont bf = BaseFont.createFont("STSong-Light","UniGB-UCS2-H",BaseFont.NOT_EMBEDDED);
                java.util.Iterator<String> it = form.getFields().keySet().iterator();
                while(it.hasNext()){
                    String name = it.next().toString();
                    form.setFieldProperty(name,"textfont",bf,null);
                    System.out.println(name);
                    form.setField(name, str[i++]);
                }
                stamper.setFormFlattening(true);//如果为false那么生成的PDF文件还能编辑，一定要设为true
                stamper.close();
    
                Document doc = new Document();
                PdfCopy copy = new PdfCopy(doc, out);
                doc.open();
                int pageNums = reader.getNumberOfPages();
                for (int i1 = 1; i1 < pageNums+1; i1++) {
                    PdfImportedPage importPage = copy.getImportedPage(
                            new PdfReader(bos.toByteArray()), i1);
                    copy.addPage(importPage);
                }
                doc.close();
    
            } catch (IOException e) {
                System.out.println(1);
            } catch (DocumentException e) {
                System.out.println(2);
            }
    
    
        }
