스프링 응용 프로그램에서 객체에 대한 속성을 찾을 수 없습니다.

calendar 유형이 AppointmentCalendar입니다. calendar.jsp이라는 JSP에서 calendar의 속성 중 하나를 calendar.day으로 부릅니다. 하지만 다음과 같은 오류가 표시됩니다.스프링 응용 프로그램에서 객체에 대한 속성을 찾을 수 없습니다.

org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 9): Field or property 'day' cannot be found on object of type

누구든지 해결 방법을 보여줄 수 있습니까? 여기

@RequestMapping("/calendar") 
public String showCalendar(Model model) { 
    LocalDate today = new LocalDate(); 
    System.out.println("------------------------ in controller, day of month is: "+today.getDayOfMonth()); 
    AppointmentCalendar calendar = new AppointmentCalendar(today); // Or whatever you do to create it 
    model.addAttribute("calendar", calendar); 
    return "appointments/calendar"; 
}

가 AppointmentCalendar이다 :

는 day 특성을 의미 calendar.jsp의 일부

    } 
}

그리고 여기에 완전한 스택 추적이 있습니다. 처음에 그들은 system.out.println() 출력이 방법이 올바른 순서로 발사되는 것을 보여주고 있음을 주목하고 day 속성 값이 있음 :

------------------------ in controller, day of month is: 6

당신은 AppointmentCalendar에 공개 getDay() 방법을 추가해야합니다은.
봄에는 day의 값을 얻기 위해이 게터가 필요합니다.

일반적으로 스프링 관리 빈/클래스를 사용할 때
은 항상 각각의 getter 및 setter 메소드를 추가합니다.
