Java 使用属性的自定义类型休眠环境

我目前在Springboot应用程序中设置Hibernate Envers时遇到问题。我的一个模型中有一个enum，它具有enum类型，而在我的PostgreSQL数据库中，列的类型为“type”

财产：

@Enumerated(STRING)
@Type(type = "pgsql_enum")
private VehicleTypes vehicleType;

此特性的模型类用以下注释：

@Entity(name = "cars")
@Audited
@TypeDef(name = "pgsql_enum", typeClass = PostgreSqlEnumType.class)

自定义类型“PostgreSqlEnumType”为：

不幸的是，当我构建它时，会出现以下错误：

对不起，所有的转储，任何帮助将不胜感激

此问题已通过解决

您需要更新到包含该修复程序的版本，以避免出现问题。因为这不是备份到5.1，所以您需要考虑最新的5.2个版本之一，包括那个修复。
