我在cassandra中有一个表，它有一个List类型的列， 当我尝试从该表中读取一行时，我发现在读取列表类型列时存在一些问题，如下所示：

但保存数据没有任何问题。

以下是实体经理的创建方式：

Map propertyMap = new HashMap();
 propertyMap.put(CassandraConstants.CQL_VERSION, CassandraConstants.CQL_VERSION_3_0);
 EntityManagerFactory emf = Persistence.createEntityManagerFactory("cassandra_pu", propertyMap);
EntityManager em = emf.createEntityManager();

以下是关于cassandra的信息：

  

[cqlsh 5.0.1 | Cassandra 2.1.12 | CQL规范3.2.1 |原生协议v3] 

<dependency>
            <groupId>com.impetus.kundera.client</groupId>
            <artifactId>kundera-cassandra</artifactId>
            <version>3.4</version>
        </dependency>

我通过安装cassandra 3.4并使用自动模式生成解决了这个问题。

我在我的resources / META-INF / persistence.xml文件中添加了这一行

<property name="kundera.ddl.auto.prepare" value="create" />
