• service - 요청 될 때마다 ( doGet, doPost )
• destroy - 서버 종료 될 때

테스트

public void init(ServletConfig config) throws ServletException {
        System.out.println("init method");
    }
    
    public void destroy() {
        System.out.println("destroy method");
    }
 
    protected void service(HttpServletRequest request, HttpServletResponse response) 
                            throws ServletException, IOException {
        System.out.println("service method");
    }
}
