在地址栏中显示视图的 URL，而不是操作的 URL

Question

@RequestMapping(value = "updatePatient", method = RequestMethod.POST)
public ModelAndView postUpdatePatientById(
        @ModelAttribute("patient") PatientForm patientForm,
        HttpSession session) {
    Long id = (Long) session.getAttribute("refId");
    if (id != 0 || id != null) {
        Patient patient1 = HospitalPatientHelper
                .getPatientFrom_PatientForm(patientForm);
        patientService.updatePatient(patient1, id);
        PatientService patientService) {
    Patient patient = patientService.getPatientById(id);
    ModelAndView mv;
    PatientForm patientForm = HospitalPatientHelper
            .getPatientForm_FromPatient(patient);
    List<Weight> weights = patientService.viewLast10RecordedWeight(patient);
    WeightTable weightTable = new WeightTable();
    List<WeightSummaryTable> summaryWeights = weightTable.summary(weights,
            patient.getHeight());
    mv = new ModelAndView("patient1/patientDetail");
    mv.addObject("patient", patientForm);
    mv.addObject("summaries", summaryWeights);
    mv.addObject("lastWeight", summaryWeights.get(0).getWeight());
    mv.addObject("bmi", summaryWeights.get(0).getBmi());
    return mv;
    } else {
        return new ModelAndView("patient1/patientDetail");
    }

}

页面成功显示，但 url 没有改变，意味着 url 没有显示地址 www.url.com/Patient1/PatientDetail.htm

并且我希望返回的视图地址也应该是也显示在网址中。

请帮我

Answer 1

使用

new ModelAndView(new RedirectView(patient1/patientDetail)).

或

redirect:patient1/patientDetail
