### Normal **FastAPI** { #normal-fastapi }

First, write all your **FastAPI** application as normally:

{* ../../docs_src/extending_openapi/tutorial001_py39.py hl[1,4,7:9] *}

 * <p>
 * Qualifiers are used to distinguish between multiple beans of the same type,
 * allowing for more precise control over which implementation should be injected.
 * Custom qualifier annotations should be annotated with {@code @Qualifier}.
 * <p>
 * Example of creating a custom qualifier:
 * <pre>
 * {@literal @}Qualifier
 * {@literal @}Retention(RUNTIME)
 * public @interface Database {
 *     String value();
 * }
 * </pre>
