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；
2.⽤pdf编辑⼯具，⽤准备表单这个⼯具在需要填充动态数据的地⽅设置⽂本框或图像框，起好标签名。
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:/";
七连屿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
BaFont bf = ateFont("C:/WINDOWS/Fonts/SIMSUN.TTC,1",BaFont.IDENTITY_H, BaFont.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";
inrtImage(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
}el{
String value = (key);
s.tField(key, value); // 为字段赋值，注意字段名称是区分⼤⼩写的
}
}
ps.tFormFlattening(true); // 这句不能少
ps.clo();
reader.clo();
/**

*/
public void inrtImage(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.tAbsolutePosition(x, y);
image.Width(), Height());
under.addImage(image);
}
catch (Exception e){
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**

属猪的public static void inrtText(PdfStamper ps, AcroFields s)
{芭蕉树
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.tTotalWidth(tatalWidth);
PdfPCell cell = new PdfPCell(new Phra(CreateChunk()));
cell.Top() - Bottom() - 1);
cell.tBorderWidth(0);
cell.tVerticalAlignment(Element.ALIGN_MIDDLE);
cell.tHorizontalAlignment(Element.ALIGN_CENTER);
cell.tLeading(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 {
心肌炎用什么药治疗最好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");怎么锻炼小腿肌肉
document.addCreationDate();
document.addTitle("XHTML to PDF");
XMLWorkerHelper worker = Instance();
String str = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"www.w3/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"
+ "<html xmlns=\"www.w3/1999/xhtml\">"

+ "<style type=\"text/css\">"

+ "</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\">"

+ "</table>" + "</body>" + "</html>";
// worker.parXHtml(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.parXHtml(pdfWriter, document, new Bytes()), null, new AsianFontProvider());
布置任务
new FileInputStream(url));
document.clo();
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
