我在启动网络服务器时遇到上述错误。 我使用了带有实体类的枚举映射。像...

@Column(name = "commission_type")
        @Type(type = "com.core.commission.model.FNEnumUserType", parameters = @Parameter(name = "type", value = "com.core.commission.dto.CommissionType"))
        private CommissionType commissionType;

有什么问题，我是否遗漏了配置中的任何内容？谢谢!!

堆栈跟踪告诉您的是，Hibernate 正在初始化自身，特别是正在执行 Configuration.generateSchemaCreationScript，它遍历所有映射表并为它们生成 DDL。作为其中的一部分，它查询现有列并将它们转换为内部 Hibernate 表示。它通过调用 ResultSetMetaData::getColumnType 来实现。然后调用TypeNames::get与结果类型代码。问题是 getColumnType 返回类型代码 1111，这意味着“other” '), Hibernate 不知道如何处理它。

基本上，您的一个表中的某处是 Hibernate 无法处理的类型的列。如果您能弄清楚那是哪一列，您就可以开始考虑如何处理它。
