 You can also use the `name` attribute if you prefer to specify the class name by using a `String` value.
 
 This mechanism does not apply the same way to `@Bean` methods where typically the return type is the target of the condition: before the condition on the method applies, the JVM will have loaded the class and potentially processed method references which will fail if the class is not present.
