org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter
但是它给出了错误

Enable Shiro Annotations for Spring-configured beans. Only run after
the lifecycleBeanProcessor has run:
<bean
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor" />
<bean
class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager" />

</beans>

堆栈跟踪显示甚至没有调用shiro过滤器。如果您的目的是首先进行shiro登录操作，然后加载hibernate对象，则应首先使用shiro过滤器，因此请更改顺序：
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>openEntityManagerFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
