Java 枚举的SpringBoot/Hibernate中的接口投影

我试图使用Hibernate本机查询从数据库中选择一个列。列类型是枚举

Java

public interface TicketSummary {

    TicketStatus getSummary();
}

@Repository
public interface TicketRepository extends JpaRepository<Ticket, TicketIdentity> {

    @Query(value = "SELECT status AS summary FROM ticket_service.ticket WHERE entitlement_id IN (:entitlementId)", nativeQuery = true)
    List<TicketSummary> findAllTicketsStatusSummary(UUID[] entitlementId);
}
我在查询时不断出现以下错误

exception captured: No Dialect mapping for JDBC type: 1111; nested exception is org.hibernate.MappingException: No Dialect mapping for JDBC type: 1111
调试

在JdbcResultMetadata.getHibernateType中放置断点将显示以下内容

请协助我找到解决方案。提前谢谢。

我猜
TicketStatus
是一个枚举。如何在
票证
实体中映射它？该实体是否正常工作？@drkblog是如果我使用Ticket pojo，它将正确映射到ticketstus枚举。以下是注释used@NotNull@Enumerated（EnumType.STRING）@Type（Type=“pgsql_enum”）私有票证状态；
