Liferay hibernate.cfg.xml 在 Liferay IDE 中制作的 portlet 中的位置
我正在尝试转换此 portlet https://github.com/tlipski/newsletter-for-liferay 它是用 maven 编译成 Liferay 项目的（然后我可以在 Liferay IDE 中使用它）。一切似乎都工作正常，但我不知道应该将 hibernate.cfg.xml 文件放在 Liferay 项目中的哪里才能使其工作。目前我将它放在 WEB-INF/classes 文件夹中，但出现此错误：

I'm trying to convert this portlet https://github.com/tlipski/newsletter-for-liferay which was made to compile with maven, to a Liferay Project (then I can work with it in the Liferay IDE). Everything seems to work fine but I don't know where should I put the hibernate.cfg.xml file in the Liferay Project to make it work. At the moment I have it in the WEB-INF/classes folder and I'm getting this error:

尝试将 hibernate.cfg.xml 文件放在 src/ 文件夹的根目录中。然后编辑 liferay-plugin-package.properties 文件并转到门户依赖项 jar。将 hibernate3.jar 添加到您的项目中。然后它应该可以在部署中工作。
Try putting the hibernate.cfg.xml file in the root of your src/ folder. Then edit the liferay-plugin-package.properties file and go to the portal dependency jars. Add the hibernate3.jar to your project. Then it should work on deployment.
