step 101: and acquiring and storing a first configuration file so that the first configuration file can be loaded when the micro service is started.
The execution subject of the management method of the configuration file in this embodiment may be a configuration center server. After the micro-service architecture is deployed, a corresponding configuration file needs to be provided for the micro-service architecture, so that the micro-service can assign values to corresponding variables contained in the micro-service architecture based on the configuration file, and the work is completed smoothly.
The configuration file can be uploaded by a user through a front-end interface, and the configuration central server needs to store the configuration file after receiving the configuration file uploaded by the user, so that related work can be conveniently carried out.
Step 102: and acquiring and storing the modified configuration file after the first configuration file is updated.
And under the condition that the configuration file needs to be updated, the user can still modify the configuration file through the front-end interface and upload the update data to the configuration center server.
Step 103: adding a configuration update message corresponding to the modified configuration file to a message queue.
After receiving the modified configuration file, the configuration center server needs to "inform" the configuration update message to the relevant microservices, so that the relevant microservices reload the modified configuration file in time, and thus, the work is carried out according to the latest configuration file.
In this embodiment, the process of notifying the micro service of the configuration update message is implemented by a message queue, and the message queue can perform message intercommunication between the configuration center server and the micro service.
Step 104: and the message queue sends the configuration updating message to the micro-service corresponding to the modification configuration file, so that the micro-service receiving the configuration updating message loads the modification configuration file.
The message queue column sends the configuration updating message to the corresponding micro-service, and the micro-service receiving the configuration updating message learns that the configuration file is updated, actively pulls the latest configuration file from the configuration center server, namely modifies the configuration file, completes corresponding loading and performs work processing according to the latest configuration file.
The management method for the configuration files can uniformly manage each configuration file in the micro-service application system, and timely inform the corresponding micro-service when the configuration file of the micro-service is updated, so that the configuration file of the micro-service can be updated timely; the configuration file can be maintained quickly and refreshed in real time, the effect that the configuration file is not required to be restarted and takes effect in real time after being updated can be achieved, and great convenience is brought to users.
In the above embodiment, the name formats of the first configuration file and the modified configuration file may be, but are not limited to: microservice name + environment type.
The microservice includes a plurality of microservices that load the first configuration file based on a load balancing policy. The load balancing policy may be any type of existing load balancing policy.
In one implementation, the obtaining and saving a first configuration file to enable the first configuration file to be loaded when the microservice is started may include: and acquiring and saving a first configuration file so that the micro-service can acquire and load the first configuration file through the REST API.
In one implementation, the obtaining and saving the first configuration file may include: and acquiring a first configuration file, and storing the first configuration file in a specified folder of a disk or a database.
In one implementation, the obtaining and saving the first configuration file may include: the method comprises the steps of obtaining a first configuration file, and storing the first configuration file through a version management tool.
It can be understood that the single application configuration file is stored in the system and pushed to the same server together with the application when deployed, however, this approach is not suitable for system applications under the microservice architecture. The technical scheme disclosed by the application can be applied to system application under a micro-service architecture, the configuration files can be managed in a unified mode, and the configuration files can be adjusted rapidly and dynamically.

1. and uploading the configuration file to the configuration center server through the portal interface by the user. The name of the configuration file has a specific format, a micro service name + an environment type (development, test, production);
2. loading files when the micro service is started, wherein the mode of loading configuration files by the micro service is obtained by calling REST API provided by a configuration center, if the configuration center is cluster deployment, the micro service needs to pass through load balancing when accessing, and after the micro service obtains the configuration files, the micro service assigns the contents of the configuration files to corresponding variables;
3. storing configuration files, wherein if version management is required, the configuration files can be stored through a git version management tool, a svn version management tool and other version management tools, can also be directly stored in a designated folder of a server disk, and can also be stored in a database;
4. a user modifies the configuration file through a portal interface, and the updated configuration file is uploaded to a configuration center;
5. the configuration center notices the change of the configuration file and informs a Message Queue (MQ) of the change of the configuration file;
6. a Message Queue (MQ) notifies each microservice of messages configuring updates;
7. and after being informed, the micro service pulls the updated configuration file from the configuration center again and assigns values to the variables in the system again.
Each time the configuration file is changed later, each micro service can be informed through the message queue, and the micro service reloads a new configuration file, so that the dynamic refreshing of the configuration file can be realized and the configuration file can be effective in real time.
