The principle of Nacos dynamic refresh mainly relies on the following two mechanisms:<\/p>\n

    \n
  1. Set up monitoring: Nacos has the capability to monitor changes in configuration files and notify relevant applications. It continuously checks for changes in configuration files in real time through long polling (long connections), and immediately notifies applications when changes occur.<\/li>\n
  2. Push Configuration: Nacos can proactively push configuration information to applications. When applications register for specific configuration files to listen to, Nacos will push the configuration information to them, allowing them to receive and process the pushed configuration information accordingly.<\/li>\n<\/ol>\n

    Based on the above mechanism, the principle of dynamic refreshing in Nacos is as follows:<\/p>\n

      \n
    1. The application will register the configuration files it needs to listen to with Nacos when it starts up.<\/li>\n
    2. Nacos will monitor changes to these configuration files and save the information of the changes.<\/li>\n
    3. When the configuration file changes, Nacos will notify the application of the changes in configuration information through long polling or configuration pushing methods.<\/li>\n
    4. The application will reload the configuration file and process it accordingly once it receives a notification, allowing for dynamic configuration refreshing.<\/li>\n<\/ol>\n

      In conclusion, Nacos achieves real-time monitoring and dynamic refreshing of configuration files through configuration listening and push mechanisms. This helps applications to promptly receive the latest configuration information, enhancing flexibility and maintainability of configurations.<\/p>\n","protected":false},"excerpt":{"rendered":"
