spring boot集成cassandra 连接带安全验证的方式

直接上代码：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.data.cassandra.config.CassandraClusterFactoryBean;
import org.springframework.data.cassandra.config.SchemaAction;
import org.springframework.data.cassandra.config.java.AbstractCassandraConfiguration;
import org.springframework.data.cassandra.repository.config.EnableCassandraRepositories;

@Configuration
@PropertySource(value = { "classpath:cassandra.properties" })
@EnableCassandraRepositories
public class CassandraConfig extends AbstractCassandraConfiguration {

   @Autowired
   private Environment env;

   @Value("${cassandra.keyspace}")
   protected String keySpace;

   @Value("${cassandra.basepackages}")
   private String basePackages;

   @Override
   protected String getKeyspaceName() {
       return keySpace;
   }

   @Override
   public String[] getEntityBasePackages() {
       return new String[] {basePackages};
   }

   @Override
   public SchemaAction getSchemaAction() {
       return SchemaAction.CREATE_IF_NOT_EXISTS;
   }

   public CassandraClusterFactoryBean cluster(){

       CassandraClusterFactoryBean cluster=new CassandraClusterFactoryBean();

       cluster.setContactPoints(env.getProperty("cassandra.contactpoints"));

       cluster.setUsername(env.getProperty("cassandra.username"));

       cluster.setPassword(env.getProperty("cassandra.password"));

       cluster.setPort(new Integer(env.getProperty("cassandra.port")));

       return cluster;
   }

}
