tomcat - CloudFoundry 上的 Grails 应用程序不会重新启动

Question

我正在使用 STS 将 Grails 应用程序部署到 CloudFoundry。一切都进行得很顺利，进行了编辑并进行了“更新和重启”。突然间，我开始遇到应用程序无法成功重启的问题。这是日志显示的内容:

Stopping Tomcat because the context stopped.

我尝试删除该应用程序，但没有帮助。我尝试删除应用程序和数据库，但这没有帮助。昨晚终于奏效的是创建一个具有不同名称的新数据库。今天，我又回到了同样的问题。

我不确定问题何时出现，但它可能与我添加 Quartz 插件和创建作业的时间有关。

显然，我不能在每次更改我的应用程序时都重新创建一个新数据库。

我该如何解决？

感谢您的建议!这让我抓狂。

Answer 1

我在使用 Grails 和 quartz 插件时遇到了问题。

当我通过 grails install quatz-plugin 命令行安装插件时，它在 grails-app 下创建了一个名为 Jobs 的文件夹，并在那里添加了它的源代码，但 STS 没有将其识别为有效的源文件夹，每次我尝试使用它时它都会让我的应用程序崩溃

在我的例子中，作业文件夹在

grails-app/jobs

未在 STS 中列为源文件夹，因此在应用程序启动时请求作业时应用程序正在死亡。
