创建名为“mongoTransactionManager”的bean时出错：设置bean属性“datastore”时无法解析对bean“mongoDatastore”的引用

Question

我正在尝试将 Grails 项目与 MongoDB 连接，但出现以下错误

创建名为“mongoTransactionManager”的 bean 时出错：在设置 bean 属性“datastore”时无法解析对 bean“mongoDatastore”的引用

我的 DataSource.groovy 文件-

    grails{
        mongo{
            host ="127.0.0.1"
            port ="27017"
            username = "blogproject"
            password = "mypassword"
            databaseName ="blogproject"
        }
    }

我已经从 BuildConfig.groovy 中删除了以下内容

//runtime ":hibernate:3.6.10.12" 
//runtime ":database-migration:1.3.8"
//compile ':cache:1.1.1'

并在 BuildConfig.groovy 中添加以下内容

   compile ":mongodb:3.0.3"

我的错误堆栈跟踪如下-

我还在 MongoDB 中添加了以下用户用于数据库“blogproject”进行身份验证

> use blogproject
switched to db blogproject
> show users;
{
        "_id" : "blogproject.blogproject",
        "user" : "blogproject",
        "db" : "blogproject",
        "roles" : [
                {
                        "role" : "readWrite",
                        "db" : "blogproject"
                },
                {
                        "role" : "dbAdmin",
                        "db" : "blogproject"
                },
                {
                        "role" : "dbOwner",
                        "db" : "blogproject"
                },
                {
                        "role" : "userAdmin",
                        "db" : "blogproject"
                }
        ]
}

看起来用户名和/或密码错误：

Failed to authenticate to database [blogproject], username = [blogproject], password = [m*********d]
