的Cloud Foundry V2 Grails中

Question

我有一个Grails项目，我想将它部署在Cloud Foundry，但控制台显示此：

我认为这是DB的Conex的问题，但我不知道解决它。我在我的应用程序和服务计划ClearDB MySQL Database Spark DB中使用MySQL。

我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anwers或建议？

尝试消除定义方言的数据源块。您仍然必须定义该块中的项目，但在每个环境的数据源中执行该项目。我这样做是因为它似乎对环境中的数据源所做的任何更改都没有影响。
