推荐答案

对于spring-data-cassandra v1.x， getSession（） org.springframework.cassandra.core.CqlOperations 可让您直接访问 Session 。但是，自v2.0以来，不再推荐使用类似的API

For spring-data-cassandra v1.x, the getSession() method of org.springframework.cassandra.core.CqlOperations could let you access Session directly. However, similar APIs are deprecated since v2.0

此处是 https://github.com/opencredo/spring-data-cassandra-example/

@Autowired
private CqlOperations cqlTemplate;//or inherited interface, like CassandraOperations

private void insertEventUsingPreparedStatement() {
  PreparedStatement preparedStatement = cqlTemplate.getSession().prepare("insert into event (id, type, bucket, tags) values (?, ?, ?, ?)");
  Statement insertStatement = preparedStatement.bind(UUIDs.timeBased(), "type2", TIME_BUCKET, ImmutableSet.of("tag1", "tag2"));
  cqlTemplate.execute(insertStatement); 
}
