我正在使用 cassandra 作为 DB 编写 JUnit。

我正在使用 EmbeddedCassandra 使用 cassandra-unit-spring 库版本 3.1.1.0 进行 JUnit 测试。

但是，当我启动 EmbeddedCassandra 服务器时。它无法加载 CQL，表明键空间不存在。

@BeforeClass
public static void setup()
{

    try
    {


        EmbeddedCassandraServerHelper.startEmbeddedCassandra("another-cassandra.yaml", 20000);
        Cluster cluster = Cluster.builder().addContactPoints("localhost").withPort(9000).build();
        Session session = cluster.connect();


        session.execute("CREATE KEYSPACE mosaickeyspace WITH replication = {'class':'SimpleStrategy', 'replication_factor' : 1}");
        session.execute("USE mosaickeyspace");

        final CQLDataLoader cqlDataLoader = new CQLDataLoader(session);
        cqlDataLoader.load(new ClassPathCQLDataSet("create-table.cql", false, true, "mosaickeyspace"));




    }
    catch(Exception excp)
    {
        LOGGER.info("Error in setup ", excp);
        System.out.println(excp.getStackTrace());

    }

}

我尝试将查询更改为大写，还尝试使用注释驱动的@EmbeddedCassandra 服务器，但没有白费。

以下是我得到的错误
