java 生成有模板表单域的 PDF

1- 准备PDF域 数据

public void createNewPDFModel(String rid, String mid, JSONArray array, Map<String, Object> resultMap) throws DocumentException, IOException {
        // TODO 自动生成的方法存根
        Match match=matchMapper.selectByPrimaryKey(mid);//赛事信息        
        Race race=raceMapper.selectByPrimaryKey(rid);//赛项信息
        List<Map<String,Object>> cupList = raceTeamScoreMapper.findCupListByMidRid(mid,rid);//奖杯
        List<Map<String,Object>> awardsList = raceTeamScoreMapper.findAwardsListByMidRid(mid,rid);//奖项
        List<Map<String,Object>> entryList = raceTeamScoreMapper.findEntryListByMidRid(mid,rid);//参赛证明
        
        String mname = removeUnlawfulFileName(match.getMname());
        String rname = removeUnlawfulFileName(race.getRname());
        //奖励证书
        String wordModelPathCup = match.getCupmodel().replace(MyProperties.getKey("RootFileUrlkey"), MyProperties.getKey("RootPathkey"));
        //wordModelPathCup="D:/pdf/奖励证书模板V4.0表单.pdf";
        for(Map<String,Object> map:cupList){
            String tname =removeUnlawfulFileName((String) map.get("tname"));
            String savePdfPath =  MyProperties.getKey("RootPathkey")+"pdf/"+mname+"/"+rname+"/奖励证书/"+mname+rname+tname+"奖励证书.pdf";
            String url =  MyProperties.getKey("RootFileUrlkey")+"pdf/"+mname+"/"+rname+"/奖励证书/"+mname+rname+tname+"奖励证书.pdf";
            File file = new File(savePdfPath);
            if (!file.exists()) {  
                // 如果路径不存在,则创建  
                 file.getParentFile().mkdirs();
            }
            Map<String, String> dataParamMap = new HashMap<String, String>();
            dataParamMap.put("编号", (String) map.get("cupno"));

            dataParamMap.put("小项", (String) map.get("rname"));
            dataParamMap.put("奖杯", (String) map.get("cup"));
            dataParamMap.put("教师",(String) map.get("teachers"));    
            dataParamMap.put("队员",(String) map.get("students"));    
            
            PdfModeForPdf.formFdfModeForPdf(dataParamMap, savePdfPath, wordModelPathCup);
            
            
            RaceTeamScore raceTeamScore = new RaceTeamScore();
            raceTeamScore.setTid((String) map.get("tid"));

            raceTeamScore.setCupurl(url);
            raceTeamScore.setCreatstatus("00");
            raceTeamScoreMapper.updateByPrimaryKeySelective(raceTeamScore);
            
        }

                String zipFilePath = MyProperties.getKey("RootPathkey")+"zip/"+mname+"/"+rname+"/";
                File file = new File(zipFilePath);
                if (!file.exists()) {  
                    // 如果路径不存在,则创建  
                     file.mkdirs();
                }

　　　　　　　　　　sourceFilePath = MyProperties.getKey("RootPathkey")+"pdf/"+mname+"/"+rname+"/奖励证书";                
                fileName = mname+rname+"奖励证书ZIP";
                FileToZip.fileToZip(sourceFilePath, zipFilePath, fileName);
                
                System.out.println("全部生成完毕");
                resultMap.put("status", 0);

有PDF模板的情况下，重新绘制PDF

1-  使用 Adobe Acrobat DC 

2-  编辑PDF > 准备表单

代码中读取PDF模板，按照排版好的域，顺序写入内容

AcroFields form = stamper.getAcroFields();

for (String key : dataParamMap.keySet()) {    
                    int ilen = dataParamMap.get(key).toString().length();
                    if(key == "学校" || key == "队伍"){
                        if(ilen >= 20 && ilen < 40){
                            form.setFieldProperty(key, "textsize", new Float(10), null);
                        }else if(ilen >= 40 && ilen <= 55){
                            form.setFieldProperty(key, "textsize", new Float(7), null);
                        }else if(ilen > 55){
                            form.setFieldProperty(key, "textsize", new Float(6), null);
                        }
                    }
                    
                    form.setField(key,dataParamMap.get(key).toString());
                }
