我正在尝试将名为transmission_result的postgres自定义类型映射到Hibernate/JPA POJO.postgres自定义类型或多或少是枚举类型的字符串值.

我创建了一个名为PGEnumUserType的自定义EnumUserType以及一个表示postgres枚举值的枚举类.当我对一个真正的数据库运行时,我收到以下错误:'错误:列"状态"的类型为transmission_result,但表达式的类型为字符变化提示:您需要重写或转换表达式.位置:135'

看到这个,我想我需要将我的SqlTypes更改为Types.OTHER.但这样做会破坏我的集成测试(在内存数据库中使用HyperSQL)和消息:'引起:java.sql.SQLException:在语句中找不到表[select enrollment0 _."id"as id1_47_0_,enrollment0 _."tpa_approval_id"as tpa2_47_0_ ,enrollment0 _."tpa_status_code"as tpa3_47_0_,enrollment0 _."status_message"as status4_47_0_,enrollment0 _."approval_id"as approval5_47_0_,enrollment0 _."transmission_date"as transmis6_47_0_,enrollment0 _."status"as status7_47_0_,enrollment0 _."transmit"as transmit8_47_0_ from"传输"enrollment0_ where enrollment0 _."id"=？]'

我不确定为什么更改sqlType会导致此错误.任何帮助表示赞赏.
