我有这个 Cassandra 表：

CREATE TABLE xxx ( id timeuuid PRIMARY KEY);

和这个类：

@Entity
@Table(name = "xxx", schema = "yyy")
   public class XXX {

  @Id
  @GeneratedValue
  public UUID id;
}

坚持后，我得到：

从日志中：

此客户端不支持 GenerationType.AUTO 策略 com.impetus.client.cassandra.pelops.PelopsClient

我建议你使用 Thrift 客户端。您可以通过将kundera.client.lookup.class属性更改persistence.xml为以下内容来做到这一点：

<property name="kundera.client.lookup.class" value="com.impetus.client.cassandra.thrift.ThriftClientFactory" />

另外，我建议您使用最新版本的 Kundera-Cassandra。
