ローカルマシンに接続したAmazonec2mysqlデータベースがあります。その中に。という名前のデータベースを作成しましたlocker。

BuildConfig.groovyそして、mysqlコネクタを追加するために行のコメントを外しました。

これが私のDataSource.groovyファイルです：

dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
    dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "create" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:mysql://localhost/locker?useUnicode=yes&characterEncoding=UTF-8"
            username = "anto"
            password = "****"
        }
        hibernate {
            show_sql = true
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
            pooled = true
            properties {
               maxActive = -1
               minEvictableIdleTimeMillis=1800000
               timeBetweenEvictionRunsMillis=1800000
               numTestsPerEvictionRun=3
               testOnBorrow=true
               testWhileIdle=true
               testOnReturn=true
               validationQuery="SELECT 1"
            }
        }
    }
}

しかし、grailsアプリを実行しようとすると、次のような大きなエラーが発生します。

私はgrailsにとても慣れていません。何が悪かったのか？誰か助けてもらえますか？

前もって感謝します。

使用しているユーザー名とパスワードが無効のようです。

Access denied for user 'anto'@'localhost' (using password: YES)

これはGrailsの問題ではなく、一般的な権限の問題です。

この質問をチェックしてください。リモート接続とJDBCを許可するようにMySQLを構成する方法について説明します。JDBCドライブはデータベースサーバーの実行場所やJDBCクライアントの実行場所に関係なく、TCP / IPソケットを使用してデータベースに接続するため、リモート接続を許可するようにMySQLを構成する必要がある場合があります。

そうですね、その問題には2つ（またはそれ以上）の理由があるかもしれません。1つは許可の理由であり、特定のユーザーに与える必要があります。

また、DataSource.groovyで、URLが次のように設定されていることに気付きました。 url = "jdbc:mysql://localhost/locker?useUnicode=yes&characterEncoding=UTF-8"

ちなみに、URLにmysqlポートを追加するのを忘れる可能性があります。これにより、同じ問題が発生します。私のやり方は次のようなものです。 url = "jdbc:mysql://localhost/locker:1234?useUnicode=yes&characterEncoding=UTF-8"
