Question

我从头开始创建应用程序，当我启动应用程序时，出现以下错误。我的MongoDB版本是2.6.1

我的DataSource配置如下

grails {
            mongodb {
                host = "localhost"
                port = 27017
                username = "admin"
                password = "password"
                databaseName = "sta"
            }
        }

检查official guide：

如果你想配置Grails如何连接到MongoDB，你可以使用grails-app / conf / application.yml中的以下设置来实现：
grails:
    mongodb:
        host: "localhost"
        port: 27017
        username: "blah"
        password: "blah"
        databaseName: "foo"

Answer 2

我尝试了.yml文件和.groovy文件。我还创建了一个新的样本，但它没有用。问题是随3.1.1版一起提供的插件。一旦我升级到3.1.3，问题就消失了。

Answer 3

我认为GORM插件中存在一个错误。它似乎无法识别databaseName属性。如果您使用连接字符串，它似乎确实有效。

connectionString：＆＃34; mongodb：//用户名：密码@ host：port / databaseName＆＃34;

无法使用Grails 3.1.1连接到mongo DB
