在Grails和CloudBees中使用MongoDB

Question

編輯：問題已解決，我在配置中鍵入了“生產”。 愚蠢的錯誤...

我使用可在我的本地計算機上運行的MongoDB創建了一個小的框架Grails應用程序。 我可以使用bees app:deploy target/proj-0.1.war -appid user/proj成功地在CloudBees上部署應用程序，並且它可以工作（當然，數據庫除外）。

然后，我使用MongoHQ創建了一個MongoDB，並收到了地址mongodb://cloudbees:123@paulo.mongohq.com:10044/456 。 基於此，我如下編輯“ DataSource.groovy”：

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，當我使用以下命令部署應用程序時

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

然后在瀏覽器中打開URL，向數據庫發出第一個請求后，我會收到以下錯誤：

在http://wiki.cloudbees.com/bin/view/RUN/MongoHQ上，它說我也可以如下使用綁定：

bees app:bind -a proj -r mongohq:db -as DB

但是，我不確定這將如何解決這個問題。 有任何想法嗎？ 我在“ DataSource.groovy”中的輸入是否錯誤？ 謝謝你的幫助。

Answer 1

您在配置“producution”做了一個錯字與“ 生產 ”

對於綁定資源，可以使用：

def url = System.getProperty('MONGOHQ_URL_DB') 

在grails配置文件中，但是CloudBees僅注入完整的URL，而不注入主機，端口等，因此可以使用新的java.net.URI（url）.host
