Tomcat没有'；t从Grails启动.war文件

我正在使用Grails1.3.7和Tomcat8

我从Grails应用程序创建了一个.war文件，以便在Tomcat8中启动它。我使用

grailswar

命令创建了它

我阻止了雄猫。然后我将.war文件放在webapps文件夹中，并再次启动tomcat。 当我转到Web应用程序管理器时，有我的应用程序，但未启动。如果我点击

Start

什么都没有发生。另外，如果我在部署表单中上传它，我可以在管理器中找到它，但没有启动

我没有收到错误消息。我该怎么做才能开始呢

这是我的stacktrace.log文件

您似乎没有为

生产

环境正确配置

数据源

。请参阅：

发布Tomcat日志，否则无法提供帮助you@lukelazarovic无论如何，您似乎没有指定足够的凭据来连接到生产数据库。您是否真的以

root

用户身份连接？您是否需要

创建drop

生产数据库？我为生产数据库配置的数据源错误。我编辑了它，现在它工作了。太多了
