我已经为login.jsp创建了登录片段，它完全正常。
现在我需要添加一些代码来从自定义表中获取一些数据，所以我使用scriptlet添加了XYZLocalServiceUtil调用。
现在服务调用正在运行，但问题是当我部署片段钩子时它会出现以下错误并且portlet变得不可用，但仅在部署后第一次出现。
当我刷新页面时，下次正常工作时没有任何错误。我不确定为什么它第一次无法获得以下依赖。

我试过在gradle文件中添加以下依赖项但没有运气。 编译组：'org.glassfish'，名称：'javax.el'，版本：'3.0.0'
我正在使用“liferay-ce-portal-7.0-ga4”，如果有人遇到类似问题，请提出解决问题的方法。
