= CDI extension for OCI Object storage
:description: Helidon CDI extension for HikariCP
:keywords: helidon, java, microservices, microprofile, extensions, cdi, oci, object storage

:oci-objstore-url: https://docs.cloud.oracle.com/iaas/Content/Object/Concepts/objectstorageoverview.htm

This link:{cdi-extension-api-url}[CDI portable extension] provides support for
 injecting an link:{oci-objstore-url}[Oracle Cloud Infrastructure Object Storage client]
 in your Helidon MicroProfile applications.

== Prerequisites

Declare the following dependency in your project:

[source,xml]
----
<dependency>
     <groupId>io.helidon.integrations.cdi</groupId>
     <artifactId>helidon-integrations-cdi-oci-objectstorage</artifactId>
</dependency>
----

== Injecting an Object Storage client

[source,java]
.Field-injection example
----
 @Inject
 private ObjectStorage client;
----

[source,java]
.Constructor-injection example
----
 private final ObjectStorage client;
 @Inject
 public YourConstructor(@Named("orders") ObjectStorage client) {
   super();
   this.client = client;
 }
----

The extension implements this injection point by creating an Object Storage client
 object in the link:{cdi-applicationscoped-api-url}[application scope].

You can configure the object using
 <<microprofile/02_server-configuration.adoc, MicroProfile config>>. For example,
 the Object Storage client created above can be configured as follows:

[source, properties]
.META-INF/microprofile-config.properties
----
oci.auth.fingerprint=
oci.auth.keyFile=
oci.auth.passphraseCharacters=
oci.auth.user=
oci.auth.tenancy=
oci.objectstorage.region=
oci.objectstorage.namespace=
----

These properties are described in the
 link:{oci-javasdk-url}[Oracle Cloud Infrastructure Object Storage Java SDK documentation].
