我正在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

我的数据源配置如下

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

我认为 GORM 插件中存在错误。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: "mongodb://username:password@host:port/databaseName"

详情： https ://docs.mongodb.com/manual/reference/connection-string/

查看官方指南：

如果你想配置 Grails 如何连接到 MongoDB，那么你可以使用 grails-app/conf/application.yml 中的以下设置来完成：

grails:
    mongodb:
        host: "localhost"
        port: 27017
        username: "blah"
        password: "blah"
        databaseName: "foo"

还要检查下一章：2.3 高级配置。

我尝试了 .yml 文件和 .groovy 文件。我还创建了一个新示例，但它没有用。问题在于版本 3.1.1 附带的插件。一旦我升级到 3.1.3，问题就消失了。
