运行 life ray 上的服务生成器发出
Issue while running the service builder on life ray
参考以下教程，https://www.liferay.com/documentation/liferay-portal/6.2/development/-/ai/generating-your-service-layer-liferay-portal-6-2-dev-guide-04-en我已经创建并部署了服务生成器。现在视图页面按预期显示，单击添加位置按钮时，新表单显示相应的字段，我正在输入一些数据并尝试保存数据。保存时（点击保存按钮）出现错误，日志如下，

从上面的异常来看，它看起来像 无效的 ORDER BY 表达式，所以您的查询出了问题。
您能否提供您正在使用的 示例查询 或 service.xml 代码？
