Use Nocas to split the configuration file

For details, please see the Nacos Simple Learning Tutorial of SpringCloudAliBaba Learning_Guitingting's Blog-CSDN Blog

Enter Nacos and create a new configuration file

Going back to the source code, we split some configuration files in the Service module into nacos

new configuration

Pay attention to the writing specification of Data ID. The content corresponds to the configuration file in the above figure

The content of the configuration file here is the configuration information of a database.

 

We have seen here that the upload has been successful.

Refer to the configuration file in nacos

In the above figure, we have configured the database-related configuration files in nacos

 The Blog-Article-API module configuration file is changed as follows: Note that
