sql - 连接 URL 的 Grails SqlException

Question

我有一个 Grails 应用程序，当我将其部署为 war 时，该应用程序抛出异常。该异常没有任何意义，因为我没有在 Datasource.groovy 文件中配置 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总是抛出这个异常？我已经运行了 grails clean 和 grails war 多次。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计算机上运行良好。谢谢。

异常(exception):

为了清理这个主题，需要在生产 block 中进行调整。

更换

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

到

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

会起作用的。
