Eine Dienstverbindung ist eine Verbindung mit einem beliebigen Remotedienst. Die Autokonfiguration von Spring Boot kann die Details einer Dienstverbindung nutzen und diese verwenden, um eine Verbindung mit einem Remotedienst herzustellen. Dabei haben die Verbindungsdetails Vorrang vor verbindungsbezogenen Konfigurationseigenschaften.
Wenn Sie Testcontainer verwenden, können Sie automatisch Verbindungsdetails für einen Dienst erstellen, der in einem Container ausgeführt wird, indem Sie das Containerfeld in der Testklasse kommentieren.

Im folgenden Codebeispiel wird die grundlegende Verwendung von Testcontainern veranschaulicht:
@SpringBootTest(classes = CosmosTestcontainersTest.class)

keyStore.store(out, cosmos.getEmulatorKey().toCharArray());
}
System.setProperty("javax.net.ssl.trustStore", keyStoreFile.toString());
System.setProperty("javax.net.ssl.trustStorePassword", cosmos.getEmulatorKey());

}
@Test

}
}
Um CosmosDBEmulatorContainer zu verwenden, müssen Sie ein KeyStore für TLS/SSL vorbereiten. Weitere Informationen finden Sie unter Cosmos DB Azure Module in der Testcontainers-Dokumentation. Mit @ServiceConnection ermöglicht diese Konfiguration, dass die Cosmos DB-bezogenen Beans in der App mit der Cosmos DB kommunizieren können, die in dem von Testcontainers verwalteten Docker-Container ausgeführt wird. Diese Konfiguration definiert automatisch ein AzureCosmosConnectionDetails Bean, das von der Cosmos-DB-Autokonfiguration verwendet wird, um alle verbindungsbezogenen Konfigurationseigenschaften zu überschreiben.

Mit @ServiceConnection ermöglicht diese Konfiguration den blobbezogenen Beans in der Anwendung die Kommunikation mit dem Blob Storage, der innerhalb des von Testcontainers verwalteten Docker-Containers ausgeführt wird.

Mit @ServiceConnection ermöglicht diese Konfiguration den warteschlangenbezogenen Beans in der App die Kommunikation mit dem Queue Storage, das innerhalb des von Testcontainers verwalteten Docker-Containers ausgeführt wird. Dieses Setup definiert automatisch eine AzureStorageQueueConnectionDetails Bean, die von der Autokonfiguration für Queue Storage verwendet wird, um alle verbindungsbezogenen Konfigurationsparameter außer Kraft zu setzen.
