Hi, i cloned your repo, but spring application isn't starting.

Do you have any idea about this :
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'application': Unsatisfied dependency expressed through field 'personRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personRepository': Cannot resolve reference to bean 'cassandraTemplate' while setting bean property 'cassandraTemplate'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'cassandraTemplate' defined in class path resource [org/springframework/boot/autoconfigure/data/cassandra/CassandraDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'cassandraTemplate' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'session' defined in class path resource [com/lankydan/CassandraConfig.class]: Invocation of init method failed; nested exception is com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1:9042 (com.datastax.driver.core.exceptions.TransportException: [/127.0.0.1:9042] Cannot connect))

Please set up Cassandra on your local machine. It will for sure.
