Question

我有这张Cassandra表：

CREATE TABLE xxx ( id timeuuid PRIMARY KEY);

和这堂课：

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

  @Id
  @GeneratedValue
  public UUID id;
}

坚持下去，我得到：

线程“main”中的异常com.impetus.kundera.KunderaException：java.lang.IllegalArgumentException：GenerationType.AUTO此客户端不支持的策略：com.impetus.client.cassandra.pelops.PelopsClient 在com.impetus.kundera.persistence.EntityManagerImpl.persist（EntityManagerImpl.java:174）在Importer.save（StayImporter.java:80）在Importer.exec（StayImporter.java:92）在Importer.main（StayImporter.java:100） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）在java.lang.reflect.Method.invoke（Method.java:497）在com.intellij.rt.execution.application.AppMain.main（AppMain.java:144）引起：java.lang.IllegalArgumentException：GenerationType.AUTO此客户端不支持的策略：com.impetus.client.cassandra.pelops.PelopsClient 在com.impetus.kundera.persistence.IdGenerator.onAutoGenerator（IdGenerator.java:116）在com.impetus.kundera.persistence.IdGenerator.generateAndSetId（IdGenerator.java:71）在com.impetus.kundera.graph.ObjectGraphBuilder.getNode（ObjectGraphBuilder.java:111）在com.impetus.kundera.graph.ObjectGraphBuilder.getObjectGraph（ObjectGraphBuilder.java:75）在com.impetus.kundera.persistence.PersistenceDelegator.persist（PersistenceDelegator.java:135）在com.impetus.kundera.persistence.EntityManagerImpl.persist（EntityManagerImpl.java:168） ......还有8个

来自日志：

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。您可以将kundera.client.lookup.class中的persistence.xml属性更改为以下内容：

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

另外，我建议您使用latest version of Kundera-Cassandra。
