how to use ImportSelector

1. Implement the ImportSelector interface: Create a class that implements the ImportSelector interface. This interface has one method, selectImports(), that returns an array of fully qualified class names.

2. Override the selectImports() method: In the selectImports() method, you can use any logic to determine which classes to include in the import. For example, you can use annotations or configuration properties to determine the classes.

3. Register the ImportSelector with Spring: You can register the ImportSelector with Spring by adding it to the @Import annotation of a configuration class. For example:

@Configuration
@Import(MyImportSelector.class)
public class MyConfiguration {
    // ...
}

4. Use the imported classes in your application: Once the ImportSelector has been registered, the classes it imports will be available for use in your application. You can use them in your code by autowiring them or creating instances of them using the ApplicationContext.
