我有一个 Grails 应用程序，当我将其部署为战争时抛出异常。该异常没有任何意义，因为我的 Datasource.groovy 文件中没有配置 Grails 内存数据库。下面是异常和我的 datasource.groovy 文件。谁能告诉我为什么它一直抛出这个异常？我已经跑grails clean了grails war好几次了。另请注意，我确实下载了 Oracle 驱动程序，并且该应用程序在我的开发机器上运行良好。谢谢。

例外：

只是为了清理这个主题，它需要在生产块中进行调整。

更换

production {
  dataSource {
    dbCreate = ""
    "jdbc:oracle:thin:@localhost:DB"

至

production {
  dataSource {
    dbCreate = ""
    url = "jdbc:oracle:thin:@localhost:DB"

将工作。
