在grails验证器中包含查询时获取堆栈溢出

您应该使用withNewSession - 请参阅http://adhockery.blogspot.com/2010/01/upgrading-grails-11-12.html

编辑:为1.1.x添加:

如果您还没有使用1.2并且withNewSession()不可用,您可以在BootStrap中自己连接:

import org.hibernate.Session
import org.springframework.orm.hibernate3.HibernateCallback
import org.springframework.transaction.support.TransactionSynchronizationManager
import org.springframework.orm.hibernate3.SessionHolder
import org.springframework.orm.hibernate3.HibernateTemplate

class BootStrap {

   def grailsApplication
   def sessionFactory

   def init = { servletContext ->
      for (domainClass in grailsApplication.domainClasses) {
         domainClass.metaClass.static.withNewSession = { Closure callable ->
            HibernateTemplate template = new HibernateTemplate(sessionFactory)
            SessionHolder sessionHolder = TransactionSynchronizationManager.getResource(sessionFactory)
            Session previousSession = sessionHolder?.session
            try {
               template.alwaysUseNewSession = true
               template.execute({ Session session ->
                  sessionHolder.addSession(session)
                  callable(session)
               } as HibernateCallback)
            }
            finally {
               if (previousSession) {
                  sessionHolder.addSession(previousSession)
               }
            }
         }
      }
   }

   def destroy = {}
}
