我有"错误处理GroovyPageView:无法使用next()"如果我在控制器类
中添加注释Transactional,则在我的视图中出错控制器
@Transactional(readOnly = true)
class SomeController {
...
def sessionFactory
def list(){
def list = sessionFactory.currentSession.createSQLQuery( "some_query" ).scroll()
[ list : list ]
}
}
查看
...
<g:while test="${ list?.next() }"> <%-- exception here --%>
<g:set var="instance" value="${ list.get() }"/>
...
如果我删除 @Transactional(readOnly = true)一切正常,是否有人知道如何使用视图中的滚动条配置事务注释?
注意:我使用grails 2.4.4
更新 我尝试了这三个,没有,同样的错误;
@Transactional
class SomeController {
...
@Transactional(readOnly = true)
class SomeController {
@Transactional(readOnly = false)
def list(){
...
@Transactional(readOnly = false)
class SomeController {
@Transactional(readOnly = false)
def list(){
这里整个错误:

答案 0 :(得分:1)
@Transactional
添加到Grails用于生成控制器的模板中。控制器应该很简单并且可以使用HTTP层,并调用服务来执行事务工作和业务逻辑。从控制器中删除所有@Transactional
注释,并将所有保存,更新和删除操作移至一个或多个事务服务,然后将服务依赖注入到控制器中。
