Posted 2021-05-08

public class DBTaskRefresher implements ApplicationContextAware {
    private volatile ApplicationContext applicationContext;

    public void init() {
        //同步配置
        //使用springboot查找bean
        Collection<DBConfig> jobList = new LinkedList<>(this.applicationContext.getBeansOfType(DBConfig.class).values());
        jobList.forEach(DBConfig::updateConfig);
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }
}
