java生成PDF,并下载到本地
1、首先要写一个PDF工具类，以及相关工具
2、PDF所需jar包
iText是一种生成PDF报表的Java组件
freemarker是基于模板来生成文本输出
<dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency><dependency><groupId>com.lowagie</groupId><artifactId>itext</artifactId><version>2.1.7</version></dependency><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.23</version></dependency>
3、需要使用Adobe Acrobat pro软件把要生成的模板转换为PDF格式
打开Adobe Acrobat pro，打开模板，选择 |—— 准备表单 ，它会自动检测并命名表单域，然后保存为pdf格式即可
PDF工具类
public class PDFTemplet {private String templatePdfPath;private String targetPdfpath;private ServiceOrder order ;public PDFTemplet() {}public void PDFTemplet（File file，String basePath）thows Exception{
/*模板路径*/PdfReader reader = new PdfReader(templatePdfPath);
ByteArrayOutputStream bos=new ByteArrayOutputStream();
/* 读取*/
PdfStamper pdfStamper= new PdfStamper(reader,bos);
/*使用中文字体*/
BaseFont baseFont=BaseFont.createFont(basePath+"WEB-INF/static/SIMHEI.TTF",BaseFont.IDENTITY_H,BaseFont.EMBEDDED);
ArrayList<BaseFont> fontList=new ArrayList<>();
fontList.add(baseFont);
AcroFields s=pdfStamper.getAcroFields();
s.setSubstitutionFonts(fontList);/*需要注意的是 setField的name和命名的表单域名字要一致*/

ps.setFormFlattenning(true);
ps.close();
FileOutputStream fileSteam =new FileOutPutStream(file);
fos.write(bos.toByteArray)；
fos.close();}}调用方法
