我正在尝试在我的应用程序中实现分页。目前，我试图在实现导航之前只查看第一条记录，但是我遇到了一个错误，我不确定我的配置是否准确。我实现了 PagedListHolder 但我不确定是否需要为此定义一个类似的泛型类。

我收到以下错误：

错误：

org.springframework.beans.NotReadablePropertyException: Invalid property 'crimeRecNo' of bean class [org.springframework.beans.support.PagedListHolder]: Bean property 'crimeRecNo' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

监控类

public class Monitoring {

    private int monitoringId;
    private int socialSecurityNumber;
    private int monitoringTypeId;
    private String monitoringStDate;
    private String monitoringEndDate;
    private int crimeRecNo;
    /**
     * 
     */
    public Monitoring() {

    }

//setters and getters 
public void setSocialSecurityNumber(int socialSecurityNumber) {
        this.socialSecurityNumber = socialSecurityNumber;
    }

public int getSocialSecurityNumber() {
        return socialSecurityNumber;
    }

控制器

@RequestMapping(value = "monitoringList.htm", method = RequestMethod.GET)
        public ModelAndView handleMonitoring(@RequestParam(value="crimeRecNo")byte[] crimeRecNo, Model model,
                @ModelAttribute Monitoring monitoring, BindingResult result,ModelMap m) throws Exception {

            String  dcryCrimeRecNo = StringSecurity.decrypt(crimeRecNo);
            int i_crimeRecNo = Integer.parseInt(dcryCrimeRecNo);


            myMonitoringTypeList.put("monitoringTypeList",this.monitoringTypeManager.getListOfMonitoringType());

            model.addAttribute("monitoringType",myMonitoringTypeList);


            PagedListHolder<Monitoring> citizenPage = new PagedListHolder<Monitoring>(this.monitoringManager.getMonitoringRecordsByCrimeRecNo(i_crimeRecNo));

            //citizenPage.setPageSize(0);   

            citizenPage.setPage(0);



            model.addAttribute("crimeRecNo", i_crimeRecNo);
            model.addAttribute("monitoring", citizenPage);



            return new ModelAndView("monitoringList"); 
        }

您正在使用 2 个模型

model.addAttribute("crimeRecNo", i_crimeRecNo);

和

return new ModelAndView("monitoringList","monitoring",citizenPage);

JSP 试图从您的模型中访问“crimeRecNo”，但您的模型已经是没有此属性的“citizenPage”，您可以像这样开发它

model.addAttribute("crimeRecNo", i_crimeRecNo);
model.addAttribute("monitoring", citizenPage);
return "monitoringList";

您也在使用更新 1

<form:form id="monitoringList" name="monitoringList" commandName="monitoring">

然后

<form:input type="hidden" path="crimeRecNo" name = "crimeRecNo" value="${crimeRecNo}"/>

所以它在citizenPage的“monitoring”中寻找“crimeRecNo”
