从 1.3.5 升级到 1.3.9 时如何修复 grails 配置错误？

Question

我很难让我的 Grails 应用程序运行。我被分配将项目从 grails 1.3.5 更新到 1.3.9 并让一切运行起来。这个项目很老，所以有些东西已经过时了。我不得不重新定位并添加一个丢失的 webflow 插件，并更新数据库连接。问题似乎出在 DataSource.groovy 文件中的 cache.provider_class 上。我注释掉了 OSCacheProvider，因为我收到一个错误，指出它无法找到并得知不再支持 OSCache。然后我用我看到的另一个 Grails 项目中使用的 EhCacheProvider 替换了它。我不确定错误指向什么，但我认为它与我在项目中看不到的 ehCache.xml 文件有关。

有什么想法吗？我对 grails 和数据库还很陌生，所以如果我没有正确解释细节，我深表歉意。

谢谢！

DataSource.groovy

​​>

dataSource {
    pooled = true   
    driverClassName = "oracle.jdbc.driver.OracleDriver"
    username = "**********"
    password = "**********"
    dialect = "org.hibernate.dialect.Oracle9Dialect"
}

hibernate {
    cache.use_second_level_cache=true
    cache.use_query_cache=true
    cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider'
    //cache.provider_class='com.opensymphony.oscache.hibernate.OSCacheProvider' //Outdated
}
// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "update" // one of 'create', 'create-drop','update'
            url = "*********************"
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "*********************"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "*********************"
            username = "********"
            password = "********"
        }
    }
}

如果您打算在旧版本的 Grails 中使用这个新的缓存提供程序，您需要为它安装插件。

http://grails.org/plugin/cache-ehcache

然后，您将拥有所有必要的文件/配置 xml。
