java - JasperReports 与 Maven 和 Eclipse 示例

Question

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。

1. JasperReport 站点似乎没有任何 Maven 教程
2. Maven 2 JasperReports 插件在生命周期配置未涵盖的 Eclipse 插件执行中给出以下错误:org.codehaus.mojo:jasperreports-maven-plugin:1.0- beta-2:编译报告
3. 其他站点上的大多数示例都是使用 Ant 和 Jasper 的

Answer 1

它是一个获取数据的小报告。

这是你的 Controller

@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;
