You can’t use Keycloak adapters with spring-boot 3 for the reason you found, plus a few others related to transitive dependencies.

Don’t panic, it’s an easy task with spring-boot. “Official” staters … Read more

I was able to solve this by downgrading Spring Boot: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>2.3.3.RELEASE</version> </dependency> Guess it’s just not compatible with 2.4.0 yet. Specifically I also had to ensure that I used 2.3.3.RELEASE and not anything more recent due to other issues I ran across.

With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the application.properties spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver spring.datasource.url=jdbc:oracle:thin:@DB… spring.datasource.username=username spring.datasource.password=pass spring.jpa.database-platform=org.hibernate.dialect…. spring.jpa.show-sql=true Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your … Read more
How do I disable JUnit coming from the Gradle Spring Dependency Management plugin? For starters, if you are using the dependency management plugin from Spring, you should not be importing the junit-bom since that results in duplicate (and potentially conflicting) management of those dependencies. Aside from that, whenever you use the dependency management plugin from … Read more
