spring mvc OpenSessionInViewFilter hibernate 懒加载问题

之前做了一个项目是使用 springmvc 加hibernate 做的, 并且使用了 hibernate 的懒加载有用到OpenSessionInViewFilter, 现在做另一个项目, 基础代码都是上个项目的代码;

目前调试在调试权限模块, 核对了上个项目的代码基本完全一致,但是这个项目的老是无法使用懒加载,加载报 org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.user.role.Role.menuRole, no session or session was closed, 和上个项目真的完全一致了, 包括事务都看过没问题,
下面是两个项目的log4j 日志, 是不一样的

-- 上个项目的日志
