java中将表单转换为PDF
经过⽹上搜索⼤概有三种⽅式：PDF模板数据填充，html代码转换pdf，借⽤wkhtmltopdf⼯具
⼀ .PDF模板数据填充
1.新建word，在word中做出和表单⼀样的布局的空表单，然后另存为pdf；
3.根据标签名向pdf中插⼊数据，并将PDF导出在指定位置。
String rootPath="d:/";
String path=rootPath+"dzyjjsdjd.pdf";
System.out.println("电⼦⽂件移交与接收登记单模板位置:"+path);
SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");//设置⽇期格式
String newPath=rootPath+df.format(new Date())+"dzyjjsdjd.pdf";
/
/读⼊pdf表单
PdfReader reader = new PdfReader(path);
//根据表单⽣成⼀个新的pdf
PdfStamper ps = new PdfStamper(reader,new FileOutputStream(newPath));
//获取pdf表单
AcroFields s = ps.getAcroFields();
//给表单添加中⽂字体这⾥采⽤系统字体。不设置的话，中⽂可能⽆法显⽰
BaseFont bf = ateFont("C:/WINDOWS/Fonts/SIMSUN.TTC,1",BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
s.addSubstitutionFont(bf);
//遍历pdf表单表格，同时给表格赋值
Map<String,String> paraMap=getMapData(accept);//⾃⼰的数据，按模板中设置的表单标签封装进map
for (String key : paraMap.keySet()) {
if(key.equals("yz1")){//获取标签为yz1的pdf标签，设置其值
String value = (key);
tempImgPath1=rootPath+"yz1.png";
insertImage(ps, tempImgPath1,"yz1",s);
//图⽚插⼊后需要去除掉设置的这个图⽚框，否则会遮当前插⼊的图⽚
}else{
String value = (key);
s.setField(key, value); // 为字段赋值，注意字段名称是区分⼤⼩写的
}
}
ps.setFormFlattening(true); // 这句不能少
ps.close();
reader.close();
/**
* 向pdf中插⼊图⽚
* @param ps pdf对象
* @param img 需要插⼊的图⽚路径
* @param col 需要插⼊图⽚的pdf字段标签名
* @param s pdf字段
*/
public void insertImage(PdfStamper ps, String img,String col,AcroFields s){
try{
List<AcroFields.FieldPosition> list = s.getFieldPositions(col);
Rectangle signRect = (0).position;
Image image = Instance(img);
PdfContentByte under = ps.getOverContent(1); //要插⼊图⽚的页数，现在只有1页
float x = Left();
float y = Bottom();
System.out.println(x);
System.out.println(y);
image.setAbsolutePosition(x, y);
image.Width(), Height());
under.addImage(image);
}
catch (Exception e){
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 插⼊⽂本
*
* @return
* @author WangMeng
* @date 2016年6⽉16⽇
*/
public static void insertText(PdfStamper ps, AcroFields s)
{
List<AcroFields.FieldPosition> list = s.getFieldPositions("CONNECT_NAME");
Rectangle rect = (0).position;
PdfContentByte cb = ps.getOverContent(1);
PdfPTable table = new PdfPTable(1);
float tatalWidth = Right() - Left() - 1;
table.setTotalWidth(tatalWidth);
PdfPCell cell = new PdfPCell(new Phrase(CreateChunk()));
cell.Top() - Bottom() - 1);
cell.setBorderWidth(0);
cell.setVerticalAlignment(Element.ALIGN_MIDDLE);
cell.setHorizontalAlignment(Element.ALIGN_CENTER);
cell.setLeading(0, (float) 1.1);
table.addCell(cell);
table.writeSelectedRows(0, -1, Left(), Top(), cb);
}
第⼆种：将html代码转换为pdf
import java.io.ByteArrayInputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import Document;
import PageSize;
import pdf.PdfWriter;
import l.xml.XMLWorkerHelper;
public class HtmlToPDF {
public static void main(String[] args) {
try {
Document document = new Document(PageSize.LETTER);
PdfWriter pdfWriter = Instance(document,
new FileOutputStream("c://temp//testpdf.pdf"));
document.open();
document.addAuthor("ysjiang");
document.addCreator("ysjiang");
document.addSubject("test");
document.addCreationDate();
document.addTitle("XHTML to PDF");
XMLWorkerHelper worker = Instance();
String str = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"
+ "<html xmlns=\"/1999/xhtml\">"
+ "<head>"
+ "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />"
+ "<title>HTML 2 PDF</title>"
+ "<style type=\"text/css\">"
+ "<!--"
+ "body {"
+ " margin: 20px;"
+ "}"
+ "-->"
+ "</style>"
+ "</head>"
+ "<body>"
+ "<div style=\"width:90%; height:160px;\">多情浪漫的⼈，其实内⼼的情感是⾮常脆弱的，感情的末梢，有那么⼀点⼉敏感，还有那么⼀点⼉想⼊⾮⾮。所以和浪漫多情的⼈在⼀起，⾔语⼀定要斯⽂，说话不能像⽕炮，态度⼀定要温柔 + "</div>"
+ "<hr/>"
+ "<table cellspacing=\"0\" cellpadding=\"0\" style=\"width:100%; border:1px;\">"
+ " <tr>"
+ " <td style=\"width:30%\">table中的中⽂显⽰及换⾏"
+ " </td>"
+ " <td>多情浪漫的⼈，其实内⼼的情感是⾮常脆弱的，感情的末梢，有那么⼀点⼉敏感，还有那么⼀点⼉想⼊⾮⾮。所以和浪漫多情的⼈在⼀起，⾔语⼀定要斯⽂，说话不能像⽕炮，态度⼀定要温柔、语⽓也要婉转。遇到对⽅的⼀个 + " </td>"
+ " </tr>"
+ " <tr>"
+ " <td colspan=\"2\">"
+ " <img src=\"0.jpg\" />"
+ " </td>"
+ " </tr>"
+ "</table>" + "</body>" + "</html>";
// worker.parseXHtml(pdfWriter, document, new FileInputStream("C:\\tmp\\a.htm"), null, new AsianFontProvider());
String url="G:/workProject_ces/zjdzyjjsxt/WebRoot/module/receive/register/input.jsp?pid=4&sign=0&tagg=undo&workitemId=149982394754705&activityName=rk&returnReason=&activityId=receive&time=Mon Jul 17 2017 14:25:49 GMT+ worker.parseXHtml(pdfWriter, document, new Bytes()), null, new AsianFontProvider());
new FileInputStream(url));
document.close();
System.out.println("Done.");
} catch (Exception e) {
e.printStackTrace();
}
}
}
第三种参照blog.csdn/zhangkezhi_471885889/article/details/52184700，因为要借助外部⼯具，所以部署时候会稍微⿇烦点，根据需要选⾃⼰的⽅式
