错误信息
解决方法:
1.关闭延迟加载(不推荐,我们使用延迟加载是为了提供性能)
2.在web.xml中配置Spring的开关session的时间(一定要在StrutsPrepareAndExecuteFilter 之前配置)
<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>openSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--配置struts的过滤器-->
<filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
配置openSessionInViewFilter
还有
<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
</filter>
中的org.springframework.orm.hibernate5.support.OpenSessionInViewFilter这个类的hibernate5的版本一定要和自己使用的一致,否则又会引发另一个异常
