If you are using the git profile, you need to set a Git URI in your configuration. If you have set spring.cloud.config.server.bootstrap=true, you need to use a composite configuration.

To configure Spring to use the git profile, you need to follow these steps:

1. Set a Git URI in your configuration: The Git URI specifies the location of the Git repository that contains the configuration files for your application. You can set the Git URI in your Spring configuration by specifying the spring.cloud.config.server.git.uri property. This property should be set to the URL of the Git repository.

2. Use a composite configuration if spring.cloud.config.server.bootstrap is set to true: The spring.cloud.config.server.bootstrap property determines whether the Spring Config Server should be used for bootstrapping the application. If this property is set to true, you need to use a composite configuration. A composite configuration allows you to combine multiple configuration sources, such as Git repositories or local files, into a single configuration for your application.

By following these steps, you can configure Spring to use the git profile and set a Git URI in your configuration. If you have set spring.cloud.config.server.bootstrap to true, you will also need to use a composite configuration.
