我有一个亚马逊ec2 mysql数据库，我在本地机器上连接了它。我已经在其中创建了一个名为locker的数据库。

我在BuildConfig.groovy中取消了这行的注释，以添加mysql连接器。

这是我的DataSource.groovy文件：

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"
            }
        }
    }
}

但是当我尝试运行我的grails应用程序时，我得到了一个很大的错误，如下所示：

我是grails的新手。哪里出了问题？有谁可以帮我？

提前谢谢。

mysql

grails

您使用的用户名和密码似乎无效：

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

这不是Grails的问题，这是一个通用的权限问题。

查看this问题。它讨论了如何配置MySQL以允许远程连接和JDBC。您可能需要将MySQL配置为允许远程连接，因为无论数据库服务器和JDBC客户端在何处运行，JDBC驱动器都使用TCP/IP套接字连接到数据库。

好吧，这个问题可能有两个原因(或更多)。一个是权限原因，应该给你的特定用户。

此外，我还注意到，在您的DataSource.groovy中，url设置为：url = "jdbc:mysql://localhost/locker?useUnicode=yes&characterEncoding=UTF-8"

请注意，您可能忘记在url中添加您的mysql端口，这将导致相同的问题。我这样做的方式是：url = "jdbc:mysql://localhost/locker:1234?useUnicode=yes&characterEncoding=UTF-8"
