工作中的spring定时任务

直接案例代码

【定时案例1】

/**
 * Created by lvfang on 2018/3/2.
 * 业务方回调地址定时刷新
 */
@Service
public  class FriendlySaltService {
    private Logger logger = LoggerFactory.getLogger(getClass());
    @Autowired
    private RcJunktextBusinessInfoDao rcJunktextBusinessInfoDao;

    public Map<String, RcJunktextBusinessInfo> infoMap = new ConcurrentHashMap<>();

    /**
     * 初始延迟 1秒钟 ； 固定延迟 1分钟
     * 及时刷新表rc_junktext_business_info业务方数据
     */
    @Scheduled(initialDelay = 1000, fixedRate = 60000)
    public void refresh() {
        infoMap = rcJunktextBusinessInfoDao.findAllList().stream().collect(Collectors.toMap(RcJunktextBusinessInfo::getBusinessUid, Function.identity()));
        logger.info("come into refresh , infoMap size : {}",infoMap.size());
    }

    /**
     * @param infoUid
     * @return
     * 问题描述：获取业务方信息(新代码。数据库获取)
     *
     * 原因说明：业务方信息从配置文件中获取造成每次有新的业务方接入时都要修改配置文件，不利于系统维护和业务方接入，增加工作量
     *
     * 解决方案：新建接入业务放表rc_junktext_business_info、将数据持久化到数据库中，每次获取从数据库中查询
     *

    public String getInfoMD5(String infoUid) {
        if (infoMap.isEmpty()) refresh();

        if(infoMap.get(infoUid)!=null){
            return infoMap.get(infoUid).getMd5Salt();
        }else{
            return null;
