这是我在web.xml里的配置
<filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
action:里PageResult<UserInfo> pageresult = userService.queryForPages(qo);
List<UserInfo> list = pageresult.getPageresult();
System.out.println("----->>>"+list);
这个UserInfo里面 有一个属性:
private List<Resource> resources = new ArrayList<Resource>();
他们是1对多的关系,
问题是: 我在通过Userinfo获取resources的时候, 报错:
failed to lazily initialize a collection of role: com.domain.UserInfo.resources, no session or session was closed
我上面的配置错了吗??? OpenSessionInViewFilter这个不是可以帮我把session开到action层吗》?怎么不好用????????哪里写错了?
