Você pode adicionar mais que uma função de manipulação de evento.

E sua aplicação não irá começar a receber requisições até que todos os manipuladores de eventos de `startup` sejam concluídos.

### Evento `shutdown`

Para adicionar uma função que deve ser executada quando a aplicação estiver encerrando, declare ela com o evento `"shutdown"`:

Puedes añadir más de un manejador de eventos.

Y tu aplicación no comenzará a recibir requests hasta que todos los manejadores de eventos `startup` hayan completado.

### Evento `shutdown`

Para añadir una función que debería ejecutarse cuando la aplicación se esté cerrando, declárala con el evento `"shutdown"`:

        // Create different implementations
        SearchLogEvent event1 = new TestSearchLogEvent("id1", 1L, "type1");
        SearchLogEvent event2 = new NullSearchLogEvent();
        SearchLogEvent event3 = new EmptySearchLogEvent();

        // Test polymorphic behavior
        SearchLogEvent[] events = { event1, event2, event3 };

        for (SearchLogEvent event : events) {
            // All methods should be callable without exceptions

Diese Funktionen können mit `async def` oder normalem `def` deklariert werden.

### `startup`-Event

Um eine Funktion hinzuzufügen, die vor dem Start der Anwendung ausgeführt werden soll, deklarieren Sie diese mit dem Event `startup`:

{* ../../docs_src/events/tutorial001.py hl[8] *}

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.

### `shutdown` event { #shutdown-event }

To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:

Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java

                .build();

        LogEvent event3 = Log4jLogEvent.newBuilder()
                .setLoggerName("third.logger")
                .setLevel(Level.ERROR)
                .setMessage(new SimpleMessage("test message 3"))
                .build();

        LogEvent result1 = policy.rewrite(event1);
        LogEvent result2 = policy.rewrite(event2);
        LogEvent result3 = policy.rewrite(event3);

# Testing Events: startup - shutdown

Cuando necesitas que tus manejadores de eventos (`startup` y `shutdown`) se ejecuten en tus tests, puedes usar el `TestClient` con un statement `with`:
