please advise why i am still getting the lazy initialization exception, thanks in advance.
回答1:
It seems that the order in which the filter chain is constructed depends on the order that the filter-mapping elements appear.
In other words, try putting filter-mapping of OpenSessionInViewFilter before any other filter-mapping.
Good luck with that
