Filter

이클립스 new에서 Filter 항목 클릭하면 자동생성됨

인코딩 코드 추가: request.setCharacterEncoding("UTF-8");

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

		request.setCharacterEncoding("UTF-8");
		
		chain.doFilter(request, response);
	}

추가로 필터는 Annotation이 @WebFilter이다

Exception

1) 클래스생성

2) 클래스 기본생성자 생성

public MemberException() {}

3) 예외처리해줄 메소드 생성 + super()

	public MemberException(String msg) {
			super (msg);
	}
