Micronaut offers security features that allow you to secure your endpoints easily. You can use the @Secured annotation along with predefined security rules to restrict access to specific controllers or methods. For example: import io.micronaut.security.annotation.Secured; import io.micronaut.security.rules.SecurityRule; @Controller("/secure") @Secured(SecurityRule.IS_AUTHENTICATED) public class SecureController { // Secured methods } This ensures that only authenticated users can access the methods within the SecureController.
