页面工作正常，但是当我将错误的时间段放入两个输入startStatusDate和endStatusDate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")
validate(Object o, Errors errors)
请见下文
我做错了什么？

答案 0 :(得分：0)
我已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]中的属性“startStatusDate”确实不存在 org.springframework.beans.NotReadablePropertyException 。驱动程序。让我解释一下它为什么会发生。要点是下面提到的Controller方法的参数序列不正确。
@RequestMapping(value = "/saveStatusSchedule", method = RequestMethod.POST)
public ModelAndView saveStatusSchedule(@ModelAttribute
DriverHistory driverHistory,
Driver driver,
BindingResult bindingResult)
BindingResult对象获取先前声明的参数为目标对象。 See debug in screen shot。在我的验证器类DriverHistoryValidator中，我将错误值设置为非目标对象的类字段。在我简单地改变上述方法中的参数顺序后，问题已得到修复，如：
@RequestMapping(value = "/saveStatusSchedule", method = RequestMethod.POST)
public ModelAndView saveStatusSchedule(DriverHistory driverHistory,
BindingResult bindingResult,
Driver driver)
重新排序参数后，类DriverHistory将作为BindinResult对象中的目标对象获取，验证工作正常。
