我用cassandra作为DB编写JUnits。
Iam使用EmbeddedCassandra与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。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，但没有成功。
以下是我得到的错误
