我试图在japer报告中打印arraylist值，但问题是这是我作为输出得到的结果

2014-03-11,2014-03

但是我的数组列表“adhist”应该打印输出为（逐个）

2014-03-11
2014-03

这是我的JavaSpringMVC代码

ArrayList<String> adhist = new ArrayList<String>();
    for(int i=0;i<Admission.size();i++){
        addhist.add(new AdmissionHistory());
        addhist.get(i).setAdmitdate(Admission.get(i).getAdmitdate());
        adhist.add(Admission.get(i).getAdmitdate());

        addhist.get(i).setDischargedate(Admission.get(i).getDischarge());
        if(Admission.get(i).getDischarge().equals("yes")){
        addhist.get(i).setDiagnosis(patientService.listdiagnosis(Admission.get(i).getAdmitclinicid()).get(0).getDiagnosis());
        }

        }
    model.put("adhist", adhist);
    modelAndView = new ModelAndView("pdfReportView1", model);

这是jasperreport.xml
