Connect to 2 cassandra clusters in spring data - cassandra

Question

I am trying to connect to 2 different cassandra clusters using spring data cassandra. But it always uses only the first cassandra cluster config. The second one is not taking affect. Any idea what am I doing wrong? This is the config that I am using:
First cassandra cluster config:
#Configuration
#EnableCassandraRepositories(
basePackageClasses = SourceRepository.class
)
public class SourceCassandraConfig extends AbstractCassandraConfiguration {
#Override
public String getContactPoints() {
return "localhost";
}
#Override
public int getPort() {
return "9051";
}
#Override
protected String getKeyspaceName() {
return "source_keyspace";
}
}
Second cassandra cluster config:
#Configuration
#EnableCassandraRepositories(
basePackageClasses = TargetRepository.class,
cassandraTemplateRef = "targetCassandraTemplate"
)
public class TargetCassandraConfig extends AbstractCassandraConfiguration {
#Override
public String getContactPoints() {
return "localhost";
}
#Override
public int getPort() {
return "9052";
}
#Override
protected String getKeyspaceName() {
return "target_keyspace";
}
#Override
#Bean("targetSession")
public CassandraSessionFactoryBean session() throws ClassNotFoundException {
final CassandraSessionFactoryBean session = super.session();
session.setKeyspaceName(getKeyspaceName());
session.setCluster(cluster().getObject());
return session;
}
#Override
public CassandraCqlClusterFactoryBean cluster() {
CassandraCqlClusterFactoryBean cluster = super.cluster();
cluster.setContactPoints(contactPoints);
cluster.setPort(port);
return cluster;
}
#Bean("targetCassandraTemplate")
public CassandraAdminOperations cassandraTemplate(
#Qualifier("targetSession") final CassandraSessionFactoryBean session) throws Exception {
return new CassandraAdminTemplate(session.getObject(), cassandraConverter());
}
}
I always see that only the first cluster node is getting added
com.datastax.driver.core.Cluster : New Cassandra host localhost/127.0.0.1:9051 added
What am I doing wrong?

I spent 2 days debugging this and 10 mins after posting this question, I found the fix :)
I wasn't using the cluster bean that I created properly in the session bean. So I did the following and it worked:
#Override
#Bean("targetCassandraCluster")
public CassandraCqlClusterFactoryBean cluster() {
CassandraCqlClusterFactoryBean cluster = super.cluster();
cluster.setContactPoints(contactPoints);
cluster.setPort(port);
return cluster;
}
#Bean("targetCassandraSession")
public CassandraSessionFactoryBean session(
#Qualifier("targetCassandraCluster") final CassandraCqlClusterFactoryBean cluster
) throws ClassNotFoundException {
final CassandraSessionFactoryBean session = super.session();
session.setKeyspaceName(getKeyspaceName());
session.setCluster(cluster.getObject());
return session;
}
#Bean("targetCassandraTemplate")
public CassandraAdminOperations cassandraTemplate(
#Qualifier("targetCassandraSession") final CassandraSessionFactoryBean session) throws Exception {
return new CassandraAdminTemplate(session.getObject(), cassandraConverter());
}
