Spring Initializr
Spring Initializr contains Spring Framework on Google Cloud auto-configuration support through the GCP Support entry.
GCP Messaging contains the Spring Framework on Google Cloud messaging support with Google Cloud Pub/Sub working out of the box.
Similarly to GCP Messaging, GCP Storage contains the Google Cloud Storage support with no other dependencies needed.
Spring Framework on Google Cloud Bill of Materials (BOM)
If you’re a Maven user, add our BOM to your pom.xml <dependencyManagement> section.
This will allow you to not specify versions for any of the Maven dependencies and instead delegate versioning to the BOM.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>spring-cloud-gcp-dependencies</artifactId>
<version>4.5.1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>Snapshots Repository
We offer SNAPSHOT versions of the project that always reflect the latest code changes to the underlying GitHub repository for Spring Framework on Google Cloud via the Sonatype Snapshots Repository:

Spring Boot greatly simplifies the Spring Framework on Google Cloud experience. Our starters handle the object instantiation and configuration logic so you don’t have to.
Every starter depends on the GCP starter to provide critical bits of configuration, like the GCP project ID or OAuth2 credentials location. You can configure these as properties in, for example, a properties file:
spring.cloud.gcp.project-id=[YOUR_GCP_PROJECT_ID]
spring.cloud.gcp.credentials.location=file:[LOCAL_PRIVATE_KEY_FILE]
spring.cloud.gcp.credentials.scopes=[SCOPE_1],[SCOPE_2],[SCOPE_3]These properties are optional and, if not specified, Spring Boot will attempt to automatically find them for you. For details on how Spring Boot finds these properties, refer to the documentation.

Note
|
If your app is running on Google App Engine or Google Compute Engine, in most cases, you should omit the spring.cloud.gcp.credentials.location property and, instead, let the Spring Framework on Google Cloud Core Starter find the correct credentials for those environments.
