> Neither BindingResult nor plain target object for bean name 'command' available as request attribute
짧은 영어 실력과 구글 번역기에 도움으로 해석해보자면 BindingResult이나 ‘command’ 이라는 이름의 bean 을 request의 속성으로 사용할 수 없어서 발생하는 에러인 것 같은데, 에러 로그를 확인 한 결과… 위에서 보이는 것 처럼, JSP의 Form Tag에서 에러가 발생하는 것으로 추측되어 4.3.3 version에서 Form Tag를 구현하는 FormTag를 확인해보니 commandName 관련된 메서드들이 @Deprecated 로 선언되어서 곧 없어진다고 알려주고 있었는데, 이번에 업그레이드한 5.3.22 version의 FormTag에선 commandName의 getter, setter 메서드들이 없는 것을 확인할 수 있었다.
그리고 이미지를 보면 알 수 있듯이 기존의 setCommandName 메서드에서도 modelAttribute에 commandName을 저장해서 쓰는 것을 확인할 수 있는데, 5.3.22 에선 해당 메서드가 없어지면서 변수 modelAttribute에 ‘command’가 할당되어 있기에, ‘command’ 라는 bean을 속성으로 사용할 수 없다고 에러가 발생하는 것이었다.
이렇게 된 것이니 당연하게도 해결 방법은 modelAttribute에 우리가 지정한 속성값이 set 되도록 하면 되는데, 위에서 본 것처럼 기존의 setCommandName에서도 modelAttribute의 값을 사용하고 있었으므로, setModelAttribute로 modelAttribute 값이 저장되도록 하면 문제는 해결될 것이기에, JSP form tag에 commandName 속성을 모두 modelAttribute로 변경한 후 확인해 보면 정상적으로 동작 하는 것을 확인할 수 있을 것이다.
