※ MultiActionController
- 특정 파라미터의 값이나 URL 등을 이용해여 해당 클래스의 메소드를 실행시킴.
- 비슷한 기능을 가진 메서드를 모아 불필요한 클래스를 많이 생성하는 것을 줄여줌
public [ModelAndView | Map | void] methodName(HttpServletRequest request, HttpServletResponse response)
public [ModelAndView | Map | void] methodName(HttpServletRequest request, HttpServletResponse response, SomeCommand command) |
▶ 특징
- return 값은 ModelAndView, Map, void 중의 하나여야 함
- 반드시 첫번째 파라미터의 경우는 HttpServletRequest, 두번째 파라미터의 경우는 HttpServletResponse이며, 세번째는 선택적으로 지정할 수 있음.
● MethodNameResolver 종류
◑ ParameterMethodNameResolver : 특정 파라미터의 값을 메서드 이름으로 사용
◑ InternalPathMethodNameResolver(default) : URL의 마지막 경로를 메서드 이름으로 사용
◑ PropertiesMethodNameResolver : URL과 메서드 이름의 매핑을 프로퍼티로 설정
