The substantially process of publication：
User issues in Portal operative configurations；
Portal calls the interface operation publication of Admin Service；
Admin Service publications send ReleaseMessage to each Config Service with postponing；
After Config Service receive ReleaseMessage, corresponding client is notified；
Fig. 4, which illustrates configuration center and how to send, to give out information to client.Configuration center Admin Service are issued in configuration
Afterwards, it needs that all Config Service is notified to have configuration to issue, to which Config Service can notify corresponding visitor
Family end pulls newest configuration.In view of the importance of configuration center configuration parameter data persistence, and in order to as far as possible
External dependence is reduced, is by one simple message queue of database realizing in realization.
Realization method is as follows：
Admin Service can be inserted into a piece of news record after configuration is issued toward ReleaseMessage tables, and message content is just
It is the configuration information key value of configuration publication.
Config Service there are one thread can run-down ReleaseMessage tables per second, see whether new
Message Record.
Config Service are if it find that have new Message Record, then being informed about all message listeners
（ReleaseMessageListener）Such as NotificationController.
After NotificationController obtains the key value of configuration publication, it is notified that corresponding client.
Configuration center client
