我只想使用 JasperReport+Maven+Eclipse 生成一个简单的 pdf 报告。
一段时间以来，我一直在浏览一个简单的示例，但找不到任何示例。

它是一个用于获取数据的小报告。
这是你的控制器
@RequestMapping(value ="/BMIbyage",method = RequestMethod.GET)
public ModelAndView BMIbyage(ModelAndView modelAndView, ModelMap model, Map<String, Object> map,HttpServletRequest request,
@RequestParam("syear") int syear,@RequestParam("eyear") int eyear,HttpSession session){
String childid = (String) session.getAttribute("childid");
List<AdmissionSummery> asum = new ArrayList<AdmissionSummery>();
List<PatientDetails> patientdetail = patientService.listpatientbmi();
for(int i=syear;i<=eyear;i++){
asum.add(new AdmissionSummery());
int no=0;
for(int j=0;j<patientdetail.size();j++){
int dob = Integer.parseInt(patientdetail.get(j).getDateofbirth().substring(0, 4));
float bmi = patientService.listPatient(patientdetail.get(j).getChildid()).get(0).getBmi();
if(dob ==i && (bmi<18.5)){
no=no+1;
asum.get(asum.size()-1).setNooftime(no);
}
System.out.println("no"+no);
System.out.println("j"+j);
asum.get(asum.size()-1).setDuration(syear+" "+"-"+" "+eyear);
asum.get(asum.size()-1).setYear(i);
System.out.println("BMI"+bmi);
}
System.out.println("i"+i);
}
JRDataSource datasource = new JRBeanCollectionDataSource(asum);
model.addAttribute("datasourcebmireportA", datasource);
model.addAttribute("format", "pdf");
modelAndView = new ModelAndView("pdfReportViewaddsummeryA", model);
return modelAndView;
}
