[인턴 OJT 20일차] RMI Rack view

TB_BOARD 생성

create table TB_BOARD (
	boardID int(11) not null,
	boardName varchar(100) not null,
	boardType varchar(100),
	severity int(11),
	primary key (BOARD_ID)
)ENGINE=InnoDB DEFAULT CHARACTER SET UTF8 COLLATE UTF8_GENERAL_CI;

 

ServerMain.java 생성

RMI 를 위해 ServerInterface에 Remote 상속 후

select 쿼리를 실행을 위한 List코드 작성

Severity.java

Serverity로 보드의 상태를 알 수 있다

	public static int CRITICAL 	= 0;
	public static int MAJOR 	= 1;
	public static int MINOR 	= 2;
	public static int NORMAL 	= 3;
	
	public static Severity CRI = new Severity(CRITICAL);
	public static Severity MAJ = new Severity(MAJOR);
	public static Severity MIN = new Severity(MINOR);
	public static Severity NOM = new Severity(NORMAL);
	
	private int value;
	private Severity(int value) {
		this.value = value;
	}
	
	public static Severity[] items = {CRI, MAJ, MIN, NOM};
	
	@Override
	public String toString() {
		if (this.value == CRITICAL)
			return "CRITICAL";
		else if (this.value == MAJOR)
			return "MAJOR";
		else if (this.value == MINOR)
			return "MINOR";
		else if (this.value == NORMAL)
			return "NORMAL";
		
		return null;
	}

 

클라이언트 Panel에서 보드가 삽입될 좌표 설정

private void initData() {
		// 연동에 의해 board 정보 조회
		boardList = getBoardData();  
		
		LOGGER.debug("boardList:" + boardList);
		
		for (BoardVo oneBoardVo : boardList) {

			BoardPanel boardPanel = new BoardPanel(oneBoardVo);

			this.add(boardPanel, null);
			
			LOGGER.debug(String.format("+++ TestPanel에 boardPanel(%s, %s) 추가",
					boardPanel.getWidth(), boardPanel.getHeight()));

ClientPanel/getBoardData()

DB에서 보드 정보를 가져오는 역할을 수행하고 initData로 호출된다

 

setToolTipText 메서드로 마우스를 올리면 보드정보를 알 수 있다.

private void initComponent() throws Exception {
		this.setToolTipText(boardVo.getBoardName()+boardVo.getBoardId());
	}

 

initAlarmGenerator() // 랜덤 쓰레드

private void initAlarmGenerator() {
		Thread t = new Thread(new Runnable() {
			@Override
			public void run() {
				while (true) {
					int boardId = (int)(Math.random() * 38);
					int severity = (int)(Math.random() * 4);
					
					Severity sev = Severity.items[severity];
					BoardVo severityRandom = new BoardVo();
					severityRandom.setBoardId(boardId);
					severityRandom.setSeverity(severity);
					
					LOGGER.debug("boardId:" + boardId + ", severity:" + sev);
					
					try {
						client.pushAlarm(severityRandom);
						Thread.sleep(100);
					}
					catch (Exception ex) {
						
					}
				}
			}
		});
		t.start();
