Leverage your Spring Boot utility’s configuration information (`utility.properties` or `utility.yml`) for shared settings. Quarkus can learn these information as effectively, making it easier to handle application-wide configurations.
Instance (utility.properties)
quarkus.http.port=8081
quarkus.datasource.url=jdbc:postgresql://localhost:5432/mydb
Customizing Parts (Strategic Integration)
Relying in your necessities, you would possibly need to customise parts and interactions between Quarkus and Spring Boot. Use CDI (for Quarkus) and Spring Beans as required, being aware of how these frameworks can work together via the Spring’s `ApplicationContext`.
Code Examples: Illustrative Configuration
Configuring REST Endpoints (with RESTEasy)
Think about you need to use Quarkus to create RESTful APIs, and combine them inside a Spring Boot utility.
Instance:
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.springframework.stereotype.Element;
@Path(“/quarkus”)
@Element
public class QuarkusResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String hiya() {
return “Hi there from Quarkus inside Spring Boot!”;
}
}
