编辑: 问题已解决，我在配置中输入错误的“生产”。愚蠢的错误...
我使用 MongoDB 创建了一个小型 Grails 框架应用程序，该应用程序可以在我的本地计算机上运行。我可以使用 bees app:deploy target/proj-0.1.war -appid user/proj 在 CloudBees 上成功部署应用程序并且它可以工作(当然数据库除外)。
然后我使用 MongoHQ 创建了一个 MongoDB 并收到地址 mongodb://cloudbees:123@paulo.mongohq.com:10044/456 。基于此，我编辑了我的“DataSource.groovy”如下:
environments {
development {
grails {
mongo {
host = 'localhost'
port = 27017
databaseName = 'db'
}
}
}
test {
grails {
mongo {
host = 'localhost'
port = 27017
databaseName = 'db'
}
}
}
producution {
grails {
mongo {
// based on: cloudbees:123@paulo.mongohq.com:10044/456
host = 'paulo.mongohq.com'
port = 10044
username = 'cloudbees'
password = '123'
databaseName = '456'
}
}
}
}
但是，当我使用以下命令部署应用程序时
bees config:set -a proj -P grails.env=production
grails war
bees app:deploy target/proj-0.1.war -appid user/proj
bees app:tail user/proj
然后在浏览器中打开 URL，一旦向数据库发出第一个请求，我就会收到以下错误:

在 http://wiki.cloudbees.com/bin/view/RUN/MongoHQ 上，它说我也可以使用如下绑定(bind):
bees app:bind -a proj -r mongohq:db -as DB
但是，我不确定这将如何帮助解决这个问题。有任何想法吗？我在“DataSource.groovy”中的条目是否错误？谢谢你的帮助。
最佳答案
你在配置“生产”与“生产”中打错了
对于绑定(bind)资源，您可以使用:
def url = System.getProperty('MONGOHQ_URL_DB')
在 grails 配置文件中，但 CloudBees 只注入(inject)完整的 URL，而不是主机、端口等，因此可以使用新的 java.net.URI(url).host
