项目启动时初始化一次指定业务

public class InitQuartzJob implements ApplicationListener<ContextRefreshedEvent> {

    @Override
    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
        if(contextRefreshedEvent.getApplicationContext().getParent() == null){ //只初始化一次的判断
            System.out.println("初始化的业务逻辑")
        }
    }
}
