[Java] MVC패턴의 흐름

1. java main 실행 했을때

MemberFC.service(null, ?);

1-2

MemberFC
    static void service(String cmd, ?){
    Action action = ActionMapper.getInstance().getAction(cmd);
    Frame next=action.execute(?);
    next.setVisible(true);
    }

1-3

ActionMapper 
    static{
        commands.put("menu", new NullAction(new MenuForm()));
        commands.put("list", new ListAction(new ListForm()));
        }
    static ActionMapper getInstance(){return instance;}
    Action getAction(String cmd){
        if(cmd==null) cmd="menu";
        return commands.get(cmd);
}

1-4

NullAction
    Frame execute(?){return next;}

2.MenuForm에서 리스트버튼 눌렀을때

setVisible(false);
MemberFC.service("list", ?);

2-2

MemberFC
    static void service(String cmd, ?){
    Action action = ActionMapper.getInstance().getAction(cmd);
    Frame next=action.execute(?);
    next.setVisible(true);
    }

2-3 1-3은 static이므로 이미 이전에 java main실행하면서 실행이 이미 된것으로 간주

ActionMapper  //1-3은 static이므로 이미 이전에 java main실행하면서 실행이 이미 된것으로 간주
    static{
        commands.put("list", new ListAction(new ListForm()))
}
Action getAction(String cmd){
        if(cmd==null) cmd="menu";
        return commands.get(cmd);

2-4

ListAction
    Frame execute(?){
        List<MemberBean> = list.dao.selectMemberList();
        ((ListFrom)next) .setList(list);
        return next;}

2-5

void ListForm
        setList(List<MemberBean> dbList){
            for(MemberBean bean:dbList){awtList.add(bean.getId());}
}

3.MenuForm에서 가입 버튼 눌렀을때

public void actionPerformed(ActionEvent e){
setVisible(false);
MemberFC.service("join-form", ?);
}

3-2

MemberFC
    static void service(String cmd, ?){
    Action action = ActionMapper.getInstance().getAction(cmd);
    Frame next=action.execute(?);
    next.setVisible(true);
    }

3-3

ActionMapper 
    static ActionMapper getInstance(){return instance;}
    Action getAction(String cmd){
        if(cmd==null) cmd="menu";
        if(commands.containsKey(cmd)) return commands.get(cmd);
        else throw new RuntimeException("잘못된 명령어 : "+cmd);
}
