## Pour résumer

Vous pouvez ajouter plusieurs paramètres body dans votre fonction de routage, même si une requête ne peut avoir qu'un seul body.

Il est possible d'ajouter des validateurs et métadonnées pour vos paramètres.

 *   <li>The {@code copyOf} methods will sometimes recognize that the actual copy operation is
 *       unnecessary; for example, {@code copyOf(copyOf(anArrayList))} should copy the data only
 *       once. This reduces the expense of habitually making defensive copies at API boundaries.
 *       However, the precise conditions for skipping the copy operation are undefined.

* **Veloce da programmare**: Velocizza il lavoro consentendo il rilascio di nuove funzionalità tra il 200% e il 300% più rapidamente. *
* **Meno bug**: Riduce di circa il 40% gli errori che commettono gli sviluppatori durante la scrittura del codice. *
