CQRS 架構中 一個事務生成的多個領域event 如何執行

@Model
public class Match {
	private String id;
	private Date matchDate;
	private Team teams[] = new Team[2];
	private boolean finished;
	@Inject
	public EventSourcing es;
	public void handle(MatchCreatedEvent matchCreatedEvent) {
		this.id = matchCreatedEvent.getMatchId();
		this.teams[0] = new Team(matchCreatedEvent.getMatchTeamName1());
		this.teams[1] = new Team(matchCreatedEvent.getMatchTeamName2());
		this.finished = false;
	}
	public void startMatch(Date matchDate) {
		if (this.matchDate != null)
			System.err.print("the match has started");
		es.started(new MatchStartedEvent(this.id, matchDate));
	}
	public void handle(MatchStartedEvent event) {
		this.matchDate = event.getMatchDate();
	}
	public void finishWithScore(Score score, Date matchDate) {
		if (this.matchDate == null)
			System.err.print("the match has not started");
		if (finished)
			System.err.print("the match has finished");
		es.finished(new MatchFinishedEvent(this.id, matchDate, score.getHomeGoals(), score.getAwayGoals()));
	}
	public void handle(MatchFinishedEvent event) {
		this.finished = true;
	}
	public String getId() {
		return id;
	}
	public String getHomeTeamName() {
		return teams[0].getName();
	}
	public String getAwayTeamName() {
		return teams[1].getName();
	}
	public boolean isFinished() {
		return finished;
	}
}
