我使用 grails 2.4.0 创建了一个新应用，然后将 hibernate 插件更改为 :hibernate:3.6.10.15 时，出现以下错误：

注意：我已更改 hibernate 插件（从 hibernate4:4.3.5.3 到 hibernate:3.6.10.15）以解决在安装 spring-security-core:2.0-RC3 期间运行 s2-quickstart 后出现的错误

这是新版本中的错误还是我遗漏了什么？

【问题讨论】：

在您的 conf/DataSource.groovy 中哪个休眠版本处于活动状态？
谢谢fat_mike，不知道datasource里面有没有对应的参数要改。

标签： spring security grails

【解决方案1】：

您的 conf/DataSource.groovy hibernate 部分应如下所示：

hibernate {
  cache.use_second_level_cache = true
  cache.use_query_cache = false
  cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
//cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
  singleSession = true // configure OSIV singleSession mode
}

如果您在 BuildConfig.groovy 中启用了休眠 3，您应该在 DataSource.groovy 中注释掉休眠 4 的缓存并启用休眠 3 的缓存。
