Grails 3.0.9war在外部Tomcat8中的部署不起作用

Question

我已经构建了一个在grails中运行良好的grails应用程序。我想把它放在tomcat 8网络服务器中"生产"，为了做到这一点，我已经阅读了它应该如何在这里完成。生产Tomcat也在Windows7和开发环境中运行。在我构建了war文件（没有嵌入tomcat）并将其放在tomcat的webapps目录中之后，它就爆炸了。检查tomcat经理(http://localhost:9080/manager/html)显示应用程序已部署并正在运行。然而，当点击tomcat manager中的链接时，我会得到以下堆栈：

有人知道哪里出了问题吗？

Answer 1

也有同样的问题。Ubuntu 14.04/Tomcat 8

无法确定解决问题的关键是什么，我已经做了以下工作：

• 在build.gradle中设置提供的"org.springframework.boot:spring-boot starter tomcat"
• 再次下载tomcat8（tar.gz包）
• 将tomcat从/root移动到/opt

希望这能有所帮助！
