    以下回答参考 皆我百晓生、券券喵儿 等免费微信小程序相关内容作答，并由本人整理回复。

    根据您提供的错误信息和日志记录，这似乎是一个与Hibernate框架相关的配置问题。具体来说，错误消息表明在尝试创建默认的实体映射器时出现了异常。

    以下是一些建议来解决此问题：

    1. 检查Hibernate配置：确保Hibernate配置正确地指定了数据库驱动、数据源和其他必要的设置。此外，请检查hibernate.cfg.xml文件中的内容是否正确。

    2. 确保Hibernate框架已正确安装并启动：如果您的环境中有多个Hibernate实例，则可能需要查看哪个实例正在使用特定于项目的配置。

    3. 检查Spring框架中Hibernate的配置：如果您在Spring应用程序上下文中使用了Hibernate，那么请检查Spring应用上下文中的Hibernate配置。

    4. 检查Hibernate核心库版本：确保Hibernate的核心库（包括所有依赖项）是最新且正确的。可以访问Hibernate官方网站获取最新的核心库。

    5. 清理缓存：有时候，清理缓存可能会解决问题。您可以尝试删除或清空Hibernate缓存目录以清除任何潜在的问题。

    6. 更新Hibernate版本：如果以上方法都不能解决问题，可能是Hibernate版本过旧导致的问题。在这种情况下，您可以考虑更新Hibernate到最新版本。

    7. 搜索在线社区：查找类似问题的答案可以帮助找到更具体的解决方案。

    请注意，上述建议并非适用于所有情况，因此请根据实际情况调整策略。希望这能帮助您解决问题！
