Spring Boot Adapter
Adding the Dependency
To add the starter to your project using Maven, add the following to your dependencies:
XML
<dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-spring-boot-starter</artifactId></dependency> |
Add the Adapter BOM dependency:
XML
<dependencyManagement> <dependencies> <dependency> <groupId>org.keycloak.bom</groupId> <artifactId>keycloak-adapter-bom</artifactId> <version>21.1.2</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies></dependencyManagement> |
Changes in the application.properties file
You can configure the realm for the Spring Boot adapter via the normal Spring Boot configuration. For example:
keycloak.realm = your_realm
keycloak.auth-server-url = http://127.0.0.1:8080
keycloak.ssl-required = external
keycloak.resource = your_client_id
keycloak.credentials.secret = your_client_secret
keycloak.use-resource-role-mappings = true
Note: Make sure to replace the placeholders (your_realm, your_client_id, your_client_secret) with your Keycloak realm, client ID, and client secret.
