How to ignore the spring-boot-cassandra default config to load the cassandra connection instance

I have add the dependency of cassandra starter

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-cassandra</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>


but the default config is poor for me.

org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'cassandraSession'
defined in class path resource
[org/springframework/boot/autoconfigure/data/cassandra/
CassandraDataAutoConfiguration.class]:
Invocation of init method failed; nested exception is
com.datastax.driver.core.exceptions.NoHostAvailableException:
All host(s) tried for query failed (tried: localhost/0:0:0:0:0:0:0:1:9042

(com.datastax.driver.core.exceptions.TransportException:
[localhost/127.0.0.1:9042] Cannot connect))

Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException:
All host(s) tried for query failed (tried: localhost/0:0:0:0:0:0:0:1:9042

(com.datastax.driver.core.exceptions.TransportException:
[localhost/127.0.0.1:9042] Cannot connect))

I hope the spring application not load the cassandra connection instance(like cassandraSession) when I don't haved config the '**spring.data.cassandra.***'

What can do it?

Ended up defining my own custom cluster bean

@Configuration
@EnableReactiveCassandraRepositories
public class CassandraConfig extends AbstractReactiveCassandraConfiguration {

// read contact points from config
@Value("${spring.data.cassandra.contact-points}")
private String contactPoints;

@Override
public CassandraClusterFactoryBean cluster() {
CassandraClusterFactoryBean bean = super.cluster();
bean.setContactPoints(contactPoints);
return bean;
}

You need to exclude CassandraDataAutoConfiguration to disable spring boot cassandra auto configuration e.g.

@SpringBootApplication
@EnableAutoConfiguration(exclude = { CassandraDataAutoConfiguration.class })
public class Application {
}

Then define your own Cassandra configuration e.g.

@Configuration
@EnableReactiveCassandraRepositories
public class CassandraConfig extends AbstractReactiveCassandraConfiguration {
}
