Spring.Net + Nhibernate3.2 开发框架的延迟加载问题

yu_mingyang 2014-07-08 03:52:57

我这里有一个程序，使用的是Spring.Net + Nhibernate3.2 的Winform程序，配置完成后可以进行正常的数据库操作，但是发现关联对象的延迟加载不能正常运行，异常信息为“Could not initialize proxy - no Session”，程序里使用了Spring进行事务管理，查找了一些资料，对数的解决方法是使用lazy=false，或者fetch 规避，再或者是Web里的
openSessionInViewInterceptor方式，请问在winform里面如何来配置如代理一类的东西可以开启session进行lazyload？烦了几天了，请各位大侠帮忙！部分配置如下
