使用hibernate jpa测试报错，报错信息如下：

jar包版本：

    damengVersion = '8.1.2.141'
    hibernateVersion = '5.3.15.Final'
    dmDialectHibernateVersion = '8.1.2.141'

    libs_damengConnector = [group: 'com.dameng', name: 'DmJdbcDriver18', version: damengVersion]
    libs_hibernateCore = [group: 'org.hibernate', name: 'hibernate-core', version: hibernateVersion]
    libs_dmDialectHibernate = [group: 'com.dameng', name: 'DmDialect-for-hibernate5.3', version: dmDialectHibernateVersion]

persistence.xml配置如下：

  <persistence-unit name="emf" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.DmDialect"/>
      <property name="hibernate.hbm2ddl.auto" value="update"/>
      <property name="hibernate.show_sql" value="true"/>
      <property name="hibernate.format_sql" value="true"/>
      <property name="javax.persistence.jdbc.driver" value="dm.jdbc.driver.DmDriver"/>
      <property name="javax.persistence.jdbc.url" value="jdbc:dm://ip:5236"/>
      <property name="javax.persistence.jdbc.user" value="xxx"/>
      <property name="javax.persistence.jdbc.password" value="xxxxxxxxxxxxx"/>
    </properties>
  </persistence-unit>
</persistence>

测试代码：

public class DmHibernateJPADemo {

  public static void main(String[] args) {
    EntityManagerFactory factory = Persistence.createEntityManagerFactory("emf");
    EntityManager entityManager = factory.createEntityManager();

    RtiDBConfig config = new RtiDBConfig();
    config.setId(1);
    config.setPartitions(8);
    config.setReplications(3);
    config.setTtlDays(7);
    EntityTransaction transaction = entityManager.getTransaction();

    try {
      transaction.begin();
      entityManager.persist(config);
      transaction.commit();
    } catch (Exception e) {
      e.printStackTrace();
      transaction.rollback();
    }
    RtiDBConfig result = entityManager.find(RtiDBConfig.class, 1);
    System.out.println(result);

    entityManager.close();
    factory.close();
  }
}

@Entity
@Table(name = "rtidb_config")
public class RtiDBConfig {

  @Id @GeneratedValue private long id;
  private int replications;
  private int ttlDays;
  private int partitions;

  public long getId() {
    return id;
  }

  public void setId(long id) {
    this.id = id;
  }

  public int getReplications() {
    return replications;
  }

  public void setReplications(int replications) {
    this.replications = replications;
  }

  public int getTtlDays() {
    return ttlDays;
  }

  public void setTtlDays(int ttlDays) {
    this.ttlDays = ttlDays;
  }

  public int getPartitions() {
    return partitions;
  }

  public void setPartitions(int partitions) {
    this.partitions = partitions;
  }

  @Override
  public String toString() {
    return "RtiDBConfig{"
        + "id="
        + id
        + ", replications="
        + replications
        + ", ttlDays="
        + ttlDays
        + ", partitions="
        + partitions
        + '}';
  }
}
