Question

我有一个grails项目，我想在Cloud Foundry上部署它，但控制台显示了这个：

我认为这是DB Conex的一个问题，但我不知道要修复它。我在我的应用程序和服务计划ClearDB MySQL Database Spark DB中使用MySQL。

我的Datasource.groovy是：

import org.springframework.cloud.CloudFactory

def cloud

try {
  cloud = new CloudFactory().cloud
} catch(e) {}

dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
    dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
    username = "root"
    password = "root"
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = true
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
    //cache.region.factory_class = 'org.hibernate.cache.EhCacheProvider'
}
environments {
    development {
        dataSource {
            dbCreate = "create-drop"
            url = "jdbc:mysql://localhost:8080/bbddSRL"
            username="root"
            password="root"
        }
    }
    test {
        dataSource {
            dbCreate = "create-drop"
            url = "jdbc:mysql://localhost:8080/bbddSRL"
            username="root"
            password="root"
        }
    }
production {
        dataSource {
          pooled = true
          dbCreate = 'update'
          driverClassName = 'com.mysql.jdbc.Driver'

          if (cloud) {
            def dbInfo = cloud.getServiceInfo('mysql-instance') //mysql-instance is the name of the ClearDB's service.
            url = dbInfo.jdbcUrl
            username = dbInfo.userName
            password = dbInfo.password
          } else {
            url = 'jdbc:mysql://localhost:8080/bbddSRLprod'
            username = 'root'
            password = 'root'
          }
        }
    }
}

任何修改或建议？

尝试删除定义方言的数据源块。您还必须在该块中定义项目，但在每个环境的数据源中执行此操作。我这样做是因为我对环境中的数据源所做的任何更改似乎都没有效果。
