If spring.datasource.platform is not functioning, the following steps can be taken:
- Check if the configuration is correctly set in the application.properties or application.yml file.
- Check if the necessary database driver is added to the project dependencies.
- If using a different database platform, change the value of spring.datasource.platform accordingly.
- If using an external database, check if the connection properties are correct.
- Restart the application and check if the issue is resolved.
- If none of the above solutions work, try to debug the application and see if there are any error messages or exceptions thrown related to the data source configuration.
