我在Grails 2.5.1中配置多个DataSources时遇到了问题。我使用PostgreSQL 9.4.4，H2DB和休眠4.3.10与GGTS。 我收到'Table“XX”找不到; SQL语句......”消息，并与控制台调试后，我发现会议将返回错误的驱动程序：多个数据源配置
import teste.PTes;
PTes.withSession { hibernateSession ->
hibernateSession.getJdbcConnectionAccess().obtainConnection().getMetaData().getDriverName()
}
Result: H2 JDBC Driver
这个领域类是应该对使用PostgreSQL驱动会话中运行。 这里是数据源
dataSource {
pooled = true
jmxExport = true
driverClassName = "org.h2.Driver"
username = "sa"
password = ""
}
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache=true
cache.region.factory_class = 'org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory' // Hibernate 4
}
// environment specific settings
environments {
development {
dataSource {
dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
logSql = true
}
dataSource_teste {
pooled = true

url: 'jdbc:postgresql://localhost:5432/teste'
dbCreate: 'validate'
}
}
test {
dataSource {
dbCreate = 'create-drop'
url = "jdbc:postgresql://localhost:5432/teste;DB_CLOSE_ON_EXIT=FALSE"
}
}
production {
dataSource {
dbCreate = "update"
url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"

jmxEnabled = true

maxActive = 50

}
}
dataSource_teste {

}
这里是BuildConfig：

grails.project.source.level = 1.6
//grails.project.war.file = "target/${appName}-${appVersion}.war"
grails.project.fork = [

}
}
这里是域类使用的映射：
static mapping = {
datasource 'teste'
table 'cd_pt'
id name: 'codPTes'
codPTes column: 'cod_p'
}
任何有线索？
忘了提。当使用单个数据源时，它工作正常。 –
