方法一:打印PDF表单以及在PDF中加入图片

需要的资料:

jar包:iTextAsian.jar ,itext-2.1.7.jar;

源码:

 1 public static void main(String args[]) throws IOException, DocumentException {
 2         String fileName = "D:/testPDF.pdf"; // pdf模板
 3         InputStream input = new FileInputStream(new File(fileName));
 4         PdfReader reader = new PdfReader(input);
 5         PdfStamper stamper = new PdfStamper(reader, new FileOutputStream("D:/contract.pdf"));
 6         AcroFields form = stamper.getAcroFields();
 7         fillData(form, data());
 8         stamper.setFormFlattening(true);
 9         Image image = Image.getInstance("D:/testPhoto.jpg");
10         image.scaleToFit(100, 125);
11         PdfContentByte content=null;
12         int pageCount=reader.getNumberOfPages();//获取PDF页数 
13         System.out.println("pageCount="+pageCount);
14         content =stamper.getOverContent(pageCount);
15         image.setAbsolutePosition(100, 700);
16         content.addImage(image);
17         stamper.close();
18         reader.close();
19     }
20     
21     public static void fillData(AcroFields fields, Map<String, String> data) throws IOException, DocumentException {
22         for (String key : data.keySet()) {
23             String value = data.get(key);
24             System.out.println(key+"= "+fields.getField(key)+" value="+value);
25             fields.setField(key, value);
26         }
27     }
28 
29     public static Map<String, String> data() {
30         Map<String, String> data = new HashMap<String, String>();
31         data.put("trueName", "xxxxxx");
32         data.put("idCard", "xxxxxx");
33         data.put("userName", "xxxx");
34         data.put("address", "12");
35         data.put("telephone", "123456");
36         data.put("signName","xxx");
37         return data;
38     }

注意以上引入的包一定是一下的方式,否则PDF表单中的字段不能赋值

//AcroFields
import com.lowagie.text.DocumentException;
import com.lowagie.text.Image;
import com.lowagie.text.pdf.AcroFields;
import com.lowagie.text.pdf.AcroFields.Item;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfStamper;

制作PDF表单:

利用工具Adobe Acrobat制作PDF表单

 

将制作好的表单保存到:D:/testPDF.pdf,这样点击运行代码会根据设置的字段添加对应的值。

注意:此方法中还包含怎样将图片随pdf打印出来,因为jar的原因,此种方法只能获得pdf的页数,不能获得某一个字段的具体位置,因此只能将其的位置初始化。

 

源码:

置于插入图片:还有一种能获取具体某一个字段的具体位置的方法,但是因为引入jar包的原因不能保证既满足读取pdf获取具体位置又能将PDF表单赋值

 1 // 模板文件路径
 2     String templatePath = "template.pdf";
 3     // 生成的文件路径
 4     String targetPath = "target.pdf";
 5     // 书签名
 6     String fieldName = "field";
 7     // 图片路径
 8     String imagePath = "image.jpg";
 9 
10     // 读取模板文件
11     InputStream input = new FileInputStream(new File(templatePath));
12     PdfReader reader = new PdfReader(input);
13     PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(targetPath));
14     // 提取pdf中的表单
15     AcroFields form = stamper.getAcroFields();
16     form.addSubstitutionFont(BaseFont.createFont("STSong-Light","UniGB-UCS2-H", BaseFont.NOT_EMBEDDED));
17 
18     // 通过域名获取所在页和坐标,左下角为起点
19     int pageNo = form.getFieldPositions(fieldName).get(0).page;
20     Rectangle signRect = form.getFieldPositions(fieldName).get(0).position;
21     float x = signRect.getLeft();
22     float y = signRect.getBottom();
23 
24     // 读图片
25     Image image = Image.getInstance(imagePath);
26     // 获取操作的页面
27     PdfContentByte under = stamper.getOverContent(pageNo);
28     // 根据域的大小缩放图片
29     image.scaleToFit(signRect.getWidth(), signRect.getHeight());
30     // 添加图片
31     image.setAbsolutePosition(x, y);
32     under.addImage(image);
33 
34     stamper.close();
35     reader.close();

 

但引入的包:

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;

只有这样以下方法才可用:

Rectangle signRect = form.getFieldPositions(fieldName).get(0).position;

 

方法二:将html页面打印成PDF

此种方法需要引入的jar包:itextpdf-5.3.2.jar, xmlworker-5.5.3。(注意:如果xmlworker版本不对会报:java.lang.NoSuchMethodError: com.itextpdf.tool.xml.html.pdfelement.NoNewLineParagraph.setMultipliedLeading(F)V )

源码:

 

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;

 

 

 

 public static final String HTML = "D:/template.html";
        public static final String DEST = "D:/helo.pdf";
     
       
        public void createPdf(String file) throws IOException, DocumentException {
            // step 1
            Document document = new Document();
            // step 2
            PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
            // step 3
            document.open();
            // step 4
            XMLWorkerHelper.getInstance().parseXHtml(writer, document,
                    new FileInputStream(HTML), Charset.forName("UTF-8"));
            // step 5
            document.close();
        }
     
        public static void main(String[] args) throws IOException, DocumentException {
            File file = new File(DEST);
            file.getParentFile().mkdirs();
            new TestPdf().createPdf(DEST);
        }

 

测试中文字体:

在网上找到一篇资料:

直接上源码:http://www.bubuko.com/infodetail-1301851.html

public void fillTemplate(){//利用模板生成pdf
                //模板路径
        String templatePath = "pdfFolder/template_demo.pdf";
                //生成的新文件路径
        String newPDFPath = "pdfFolder/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;
            java.util.Iterator<String> it = form.getFields().keySet().iterator();
            while(it.hasNext()){
                String name = it.next().toString();
                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();
            PdfImportedPage importPage = copy.getImportedPage(
                    new PdfReader(bos.toByteArray()), 1);
            copy.addPage(importPage);
            doc.close();
            
        } catch (IOException e) {
            System.out.println(1);
        } catch (DocumentException e) {
            System.out.println(2);
        }

        
    }                    

 

输出英文:没问题!

1 public void test1(){//生成pdf
 2         Document document = new Document();
 3         try {
 4             PdfWriter.getInstance(document, new FileOutputStream("pdfFolder/1.pdf"));
 5             document.open();
 6             document.add(new Paragraph("hello word"));
 7             document.close();
 8         } catch (FileNotFoundException | DocumentException e) {
 9             System.out.println("file create exception");
10         }
11     }

可是如果要输出中文呢,上面这个就不行了,就要用到语言包了

最新亚洲语言包:http://sourceforge.net/projects/itext/files/extrajars/

pdf显示中文:

 1 public void test1_1(){
 2         BaseFont bf;
 3         Font font = null;
 4         try {
 5             bf = BaseFont.createFont( "STSong-Light", "UniGB-UCS2-H",
 6                     BaseFont.NOT_EMBEDDED);//创建字体
 7             font = new Font(bf,12);//使用字体
 8         } catch (DocumentException | IOException e) {
 9             e.printStackTrace();
10         }
11         Document document = new Document();
12         try {
13             PdfWriter.getInstance(document, new FileOutputStream("pdfFolder/2.pdf"));
14             document.open();
15             document.add(new Paragraph("hello word 你好 世界",font));//引用字体
16             document.close();
17         } catch (FileNotFoundException | DocumentException e) {
18             System.out.println("file create exception");
19         }
20     }

 

另外一种方法:我不用第三方语言包:

我是在工程目录里面新建了一个字体文件夹Font,然后把宋体的字体文件拷贝到这个文件夹里面了

上程序:

 1 public void test1_2(){
 2         BaseFont bf;
 3         Font font = null;
 4         try {
 5             bf = BaseFont.createFont("Font/simsun.ttc,1", //注意这里有一个,1
 6                     BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
 7             font = new Font(bf,12);
 8         } catch (DocumentException | IOException e) {
 9             e.printStackTrace();
10         }
11         Document document = new Document();
12         try {
13             PdfWriter.getInstance(document, new FileOutputStream("pdfFolder/3.pdf"));
14             document.open();
15             document.add(new Paragraph("使用中文另外一种方法",font));
16             document.close();
17         } catch (FileNotFoundException | DocumentException e) {
18             System.out.println("file create exception");
19         }
20     }
