在grails中,我有一个Domain类,可以在BootStap.groovy中查询
def xref = AppXref.find{user_nm == 'john'}

但是,一旦我将代码移动到另一个Domain类的方法,我将有以下错误.
Servlet.service() for servlet [default] in context with path [/myapp] threw exception
Message: Could not obtain current Hibernate Session; nested exception is org.hibernate.HibernateException: No Session found for current thread

这是我在Config.groovy中的hibernate配置
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
flush.mode = 'manual' // OSIV session flush mode outside of transactional context
}

我将cache.use_query_cache更改为true.但它没有任何区别.

域类方法不是事务性的,因此您必须确保它们在TX上下文中调用:要么将它们放入服务中,要么使用 .withTransaction{}
