Answer 1

当然，我想你会说Grails 2.4.0。好的这是我的mongodb的DataSource.groovy：

environments {
    development {
    grails {
        mongo {
            host = "10.0.11.243"
            port = 27017
            username = "username"
            password = "userpassword"
            databaseName = "yourdb"
            options {
                autoConnectRetry = true
                connectTimeout = 300
            }
        }
    }
}
}

您必须在mongo中创建一个数据库，并且该用户可以访问它。

Answer 2

您对数据库使用了什么名称？请注意错误中的以下行：

Message: Error creating bean with name 'mongoDatastore': 
FactoryBean threw exception on object creation; nested exception is 
java.lang.IllegalArgumentException: **Database name** must only contain letters, numbers, underscores and dashes!

在配置中的某个位置，您输入了无效的数据库名称或根本没有设置一个。检查DataSource.groovy中的值。
