The invention relates to a method for realizing dynamic change of micro-service routing based on a memory database, and a storage medium, and the realization architecture comprises a local routing end, a remote routing end, a routing information management service unit, and a local database or a file system, and comprises the following steps: released routing information is updated to the remote routing end in real time; and the local routing end regularly pulls the routing information from the remote routing end and compares the routing information with the version number in the routing information in the local routing end, if the routing information is inconsistent with the version number in the routing information in the local routing end, the routing information in the local routing end is updated, the routing configuration is enabled to take effect, the dynamic change of the micro-service routing is realized, and otherwise, the routing information is continuously and regularly pulled from the remote routing end. The situation that configuration files or codes need to be modified and the routing system needs to be restarted for updating the routing information in a traditionalmicro-service routing system is changed, dynamic change and effectiveness of the routing information in the micro-service routing system are supported, the configuration files and the codes do not need to be written, and the routing system does not need to be restarted.
