1.Java通過memcache進行內容儲存public String getSysDict(String key) {

    String memKey = "_getSysDict_key_" + key;

    String dictionaryStr = (String) memcachedClient.get(memKey);
    if (StringUtils.isNotBlank(dictionaryStr)) {// 快取讀取

        return dictionaryStr;

    } else {// 資料庫讀取
        List<DictionaryDto> list = iCmsSysDao.getDicts(key);
        String returnJson = JsonUtils.toJsonString(list);
        if (!list.isEmpty()) {// 放入快取
            memcachedClient.set(memKey, returnJson, new Date(System.currentTimeMillis() + 1000 * 60 * 15));
        }

        return returnJson;
    }
}
 

2.memcached中獲取的字串轉化為map

boolean isRunning() throws Exception {
    String value = cmsService.getSysDict("PORTFOLIO_SPREAD_TIME");

    Map map = JsonUtils.toJavaBeanList(value, new TypeReference<List<Map<String, String>>>() {
    }).get(0);

    String[] array = ((String) map.get("keyvalue")).split(",");
    String startTime = array[0];
    String endTime = array[1];

    Date now = new Date();
    Date start = DateUtil.parseDate(startTime);
    Date end = DateUtil.parseDate(endTime);

    if (now.before(start) || now.after(end)) {
        return false;
    } else {
        return true;
    }
}
