Is it possible to use multiple identical Spring configurations within one project?

In a single project, you can use multiple identical Spring configurations, but it is important to understand the context. If you are dealing with multiple configuration files with the same settings, Spring will merge them, and in case of conflicts, the last loaded configuration will take precedence. For different profiles (e.g., dev, prod), you can have the same settings with different values. You can also use multiple beans with the same classes but different names or configurations.
