Spring Cloud GCP
Spring Cloud GCP contains a set of easy to use starters/autoconfigurations that allow you to easily connect and adopt GCP services.
Spring Cloud GCP is part of the Spring Cloud release train.
Even though Spring Cloud GCP is part of the Spring Cloud release train, it doesn't mean that you need to use any Spring Cloud features (Eureka, Config Server, etc.). The release train helps manage dependency versions so that you don't need to specify versions. It avoids having incompatible dependency versions, and eliminates dependency conflicts.

Configure Spring Boot Project

New Spring Boot Project

Create a new Spring Boot project use Spring Initializr, and add the GCP Support dependency.
Add the GCP Support dependency
Or, generate the project using curl:
1
curl https://start.spring.io/starter.zip \
2
-d dependencies=web,cloud-gcp,lombok \
3
-d bootVersion=2.3.1.RELEASE \
4
-d baseDir=demo
Copied!
Unpack the downloaded zip file:
1
unzip demo.zip
Copied!
The generated project will include Spring Cloud release train BOM.

Existing Spring Boot Project

If you want to add Spring Cloud GCP to existing project, simply add Spring Cloud release train configuration. Different Spring Boot version is compatible with different Spring Cloud releases.
Spring Boot Version
Spring Cloud Version
2.1
Greenwich
2.2
Hoxton
2.3
Hoxton.SR5
See Spring Cloud documentation for the latest versions.
Add the compatible Spring Cloud BOM version to your project:
Maven
Gradle
1
<dependencyManagement>
2
<dependencies>
3
<dependency>
4
<groupId>org.springframework.cloud</groupId>
5
<artifactId>spring-cloud-dependencies</artifactId>
6
<version>Hoxton.SR5</version>
7
<type>pom</type>
8
<scope>import</scope>
9
</dependency>
10
</dependencies>
11
</dependencyManagement>
Copied!

buildscript {
2
dependencies {

classpath "io.spring.gradle:dependency-management-plugin:1.0.2.RELEASE"

}

apply plugin: "io.spring.dependency-management"

dependencyManagement {

imports {
11
mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Hoxton.RELEASE'
12
}
13
}
Copied!
A BOM is a Bill of Material, when imported, you can specify dependencies managed by the BOM without explicitly specifying a version for that dependency. Using the Spring Cloud BOM will allow you to use all Google Cloud Client Libraries and Spring Cloud GCP libraries without explicitly specifying a version.
