Grails错误：表或​​视图不存在

问题描述

 错误hbm2ddl.SchemaExport  - 当您启动我的Grails应用程序时， HHH000389：不成功：drop table domain_class级联约束
错误hbm2ddl.SchemaExport -ORA-01031：权限不足
  

然后

 错误hbm2ddl.SchemaExport -ORA-00942：表或视图不存在

我正在为应用程序使用内存数据库，而我的DataSource.groovy包含它：

  dataSource {
 pooled = true 
 driverClassName =org.h2.Driver
 username =sa
 password =
} 
 hibernate {
 cache.use_second_level_cache = true 
 cache.use_query_cache = false 
 cache.region.factory_class ='net.sf. ehcache.hibernate.EhCacheRegionFactory'
} 
 //环境特定设置
环境{
本地{
数据来源{
 dbCreate =create-drop//创建'，'创建''，'更新'，'验证'，''
 url =jdbc：h2：mem： devDb; MVCC = TRUE; LOCK_TIMEOUT = 10000

} 
开发{
 dataSource {
 dbCreate =update//'create'，' '
 url =jdbc：h2：mem：devDb; MVCC = TRUE; LOCK_TIMEOUT = 10000
} 
} $ b创建删除'，'更新'，'验证' $ b test {
 dataSource {
 dbCreate =update
 url =jdbc：h2：mem：testDb; MVCC = TRUE; LOCK_TIMEOUT = 10000
} 
} 
  

DataSource中的设置有问题吗？
我使用 grails -Dgrails.env = local run-app -https

开始申请尝试使用BootStrap.groovy在启动过程中创建对象，甚至失败。我使用GGTS进行开发。这是什么特权呢？

解决方案

我们找到了答案。 resources文件夹中的文件 instanceConfig.local.properties 中的 dataSource 指向Oracle数据库，我没有配置到在那里创建或删除表的角色。因此，特权错误不足。尽管 DataSource.groovy 具有内存数据库设置，但我认为
c> instanceConfig.local.properties 会覆盖它。感谢帮助家伙！

When ever I start my Grails application, I get these errors for all my domain classes.

ERROR hbm2ddl.SchemaExport  - HHH000389: Unsuccessful: drop table domain_class cascade constraints
ERROR hbm2ddl.SchemaExport  -ORA-01031: insufficient privileges

and then

ERROR hbm2ddl.SchemaExport  -ORA-00942: table or view does not exist

I am using in-memory database for the application and my DataSource.groovy has this in it:

dataSource {
    pooled = true
    driverClassName = "org.h2.Driver"
    username = "sa"
    password = ""
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
    local {
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }
    development {
        dataSource {
            dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }

Is there something wrong with the settings in DataSource?I start my application with grails -Dgrails.env=local run-app -https

I tried to create objects during startup using BootStrap.groovy and even they fail. I use GGTS for development. What privileges is this talking about?

解决方案

We found the answer. The dataSource in file instanceConfig.local.properties in the resources folder was pointing to an Oracle database and I am not configured to a role to create or drop tables there. Hence the insufficient privileges error.

Even though the DataSource.groovy had the in-memory database setting, I assume that the instanceConfig.local.properties overrides it. Thanks anyways for the help guys!
