运行部署时，无法在tomcat中连接到驱动程序错误。

Question

我希望有人可以尽快帮助我..我能够在localhost上完全运行我的应用程序然而不幸的是，当我将一个war文件部署到tomcat并尝试运行它时，它一直给我跟随错误。 正如我所提到的，我能够连接到数据库（不是我的本地主机，而是服务器上的数据库）并获得一个REST响应也很好，我不明白为什么我会收到此错误。 是的我有所有的hibernate和postgres jar文件和添加的maven依赖关系仍然tomcat很难运行驱动程序。请帮忙！

错误日志：

不幸的是我自己遇到了解决方案，显然这对于​​不同的用户可能有所不同但是因为我从本地连接我使用外部IP地址连接到数据库服务器然而我将应用程序部署到tomcat服务器上遇到了这个例外。解;我只需要将hibernate.cfg.xml从外部IP地址更改为内部IP地址，一切正常。
