dynamic-datasource can not find primary datasource

There could be several reasons why dynamic-datasource is unable to find the primary datasource. Here are a few things you can check:

1. Make sure that the primary datasource is defined in your application.properties or application.yml file.

2. Check that the primary datasource is properly configured with the right connection details, including the database name, URL, username, and password.

3. Verify that the dynamic-datasource library is properly imported into your project and that the necessary dependencies are installed.

4. If you are using Spring Boot, make sure that the dynamic-datasource configuration is properly set up in your application class.

5. Check the logs for any error messages that may indicate why the primary datasource is not being found.

If none of these steps resolve the issue, you may need to provide more information about your application setup and configuration to help troubleshoot the problem further.
