repository binding problem with spring r2dbc - spring

Question

I try to use Spring R2DBC with postgres driver. I have the following repository:
package fr.misc.database.repos.computed;
import fr.misc.database.entities.computed.OrdreDeTravailPivotComputedEntity;
import org.springframework.data.repository.reactive.ReactiveCrudRepository;
public interface OrderRepository extends ReactiveCrudRepository<OrderEntity, String> {
}
And I tried several annotations like that:
package fr.misc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.data.r2dbc.repository.config.EnableR2dbcRepositories;
#EnableJpaRepositories(basePackages = {"fr.misc.database.repos.common"})
#EntityScan("fr.misc")
#ComponentScan("fr.misc")
#SpringBootApplication
#EnableConfigurationProperties
#EnableR2dbcRepositories("fr.misc.database.repos.computed")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
With my connection factory like this:
package fr.misc;
import io.r2dbc.spi.ConnectionFactories;
import io.r2dbc.spi.ConnectionFactory;
import io.r2dbc.spi.ConnectionFactoryOptions;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.r2dbc.config.AbstractR2dbcConfiguration;
#Configuration
public class DatabaseConfiguration extends AbstractR2dbcConfiguration {
#Value("${spring.data.postgres.host")
private String host;
#Value("${spring.data.postgres.port}")
private int port;
#Value("${spring.data.postgres.database}")
private String database;
#Value("${spring.data.postgres.username}")
private String username;
#Value("${spring.data.postgres.password}")
private String password;
#Override
public ConnectionFactory connectionFactory() {
// return new PostgresqlConnectionFactory(PostgresqlConnectionConfiguration.builder().host(host)
// .port(port).database(database).username(username).password(password).build());
return ConnectionFactories.get(ConnectionFactoryOptions.builder()
.option(DRIVER, POSTGRESQL_DRIVER)
.option(DATABASE, database)
.option(HOST, host)
.option(PORT, port)
.option(PASSWORD, password)
.option(USER, username)
.build());
}
}
and the application.yml:
data:
postgres:
host: locahost
port: 5432
database: postgres
username: postgres
password: postgres
But I always got the following exception:

And bellow my OrderConverter constructor:
#Slf4j
#Component
public class OrderConverter {
private final OrderComputedRepository orderComputedRepository;
#Autowired
public OrderConverter(OrderComputedRepository orderComputedRepository) {
this.orderComputedRepository = orderComputedRepository;
}
Do you have an idea why my repository bean isn't bound ?
Thank all and best regards

Answer 1

The error says:
No qualifying bean of type 'ffr.misc.database.repos.computed.OrderRepository'
Looks like there is an additional 'f' at the beginning of your package.
So I don't know if the code you shared is the exact one, but at least it does not match your annotation
#EnableR2dbcRepositories("fr.misc.database.repos.computed")
