java - org.springframework.beans.NotReadablePropertyException:Bean类的无效属性。 Thymeleaf + SpringBoot

错误详情

该页面工作正常，但是当我在两个输入startStatusDate和endStatusDate中输入了不正确的时间段时。验证检查类DriverHistoryValidator中的错误时发生错误。

我在调试器中看到分配后生成的异常

errors.rejectValue("startStatusDate",
"co.driverHistoryStatusPeriod.notpermitted")

方法中

validate(Object o, Errors errors)

请看下面

我究竟做错了什么？

                  th:method="POST"
                  th:object="${driverHistory}">

验证器：

@Component
public class DriverHistoryValidator implements Validator {

    @Autowired
    DriverHistoryService driverHistoryService;

    @Override
    public boolean supports(Class<?> aClass) {
        return DriverHistory.class.equals(aClass);
    }

    @Override
    public void validate(Object o, Errors errors) {
        DriverHistory driverHistory = (DriverHistory) o;
        if (driverHistoryService.isExistDriverStatusInPeriodOf(driverHistory)) {
            errors.rejectValue("startStatusDate", "co.driverHistoryStatusPeriod.notpermitted");
        }
    }
}

实体：

@Entity
@Table(name = "CO_DRIVER_HISTORY")
public class DriverHistory extends BaseEntity {

    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm")
    @Column(name = "startStatusDate")
    private Date startStatusDate;

    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm")
    @Column(name = "endStatusDate")
    private Date endStatusDate;

    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm")
    @Column(name = "startShiftDate")
    private Date startShiftDate;

    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm")
    @Column(name = "endShiftDate")
    private Date endShiftDate;

    @ManyToOne
    @JoinColumn(name = "DriverId")
    private Driver driver;

    @ManyToOne
    @JoinColumn(name = "DriverStatusId")
    private DriverStatus driverStatus;

    @ManyToOne
    @JoinColumn(name = "DriverShiftId")
    private DriverShift driverShift;

    public DriverHistory() {
    }

    public Date getStartStatusDate() {
        return startStatusDate;
    }

    public void setStartStatusDate(Date startStatusDate) {
        this.startStatusDate = startStatusDate;
    }

    public Date getEndStatusDate() {
        return endStatusDate;
    }

    public void setEndStatusDate(Date endStatusDate) {
        this.endStatusDate = endStatusDate;
    }

    public Date getStartShiftDate() {
        return startShiftDate;
    }

    public void setStartShiftDate(Date startShiftDate) {
        this.startShiftDate = startShiftDate;

    public Date getEndShiftDate() {
        return endShiftDate;
    }

    public void setEndShiftDate(Date endShiftDate) {
        this.endShiftDate = endShiftDate;
    }

    public Driver getDriver() {
        return driver;
    }

    public void setDriver(Driver driver) {
        this.driver = driver;
    }

    public DriverStatus getDriverStatus() {
        return driverStatus;
    }

    public void setDriverStatus(DriverStatus driverStatus) {
        this.driverStatus = driverStatus;
    }

    public DriverShift getDriverShift() {
        return driverShift;
    }

    public void setDriverShift(DriverShift driverShift) {
        this.driverShift = driverShift;
    }

}

最佳答案

我已经找出问题的根本原因。让我回答自问的问题。

在我的情况下，类[kg.nurtelecom.dictionaries.entity.carordering.Driver]中实际上不存在自属性“ startStatusDate”以来生成的org.springframework.beans.NotReadablePropertyException。让我解释一下为什么会发生。重点是以下提到的控制器方法的参数顺序不正确。

@RequestMapping(value = "/saveStatusSchedule", method = RequestMethod.POST)
    public ModelAndView saveStatusSchedule(@ModelAttribute
                                                   DriverHistory driverHistory,
                                                   Driver driver,
                                                   BindingResult bindingResult)

在参数中声明的BindingResult对象获取先前声明的参数作为目标对象。 See debug in screen shot。在我的验证器类DriverHistoryValidator中，将错误值设置为不是目标对象的类的字段。在我简单地更改上述方法中的参数顺序之后，该问题已解决：

@RequestMapping(value = "/saveStatusSchedule", method = RequestMethod.POST)
public ModelAndView saveStatusSchedule(DriverHistory driverHistory,
                                       BindingResult bindingResult,
                                       Driver driver)

对参数重新排序后，将获得类DriverHistory作为BindinResult对象中的目标对象，并且验证可以正常进行。
