Org. hibernate. lazyinitializationexception: cocould not initialize proxy-No session

Exception in lazy loading: org. hibernate. lazyinitializationexception: cocould not initialize proxy-No session

I thought it was my configuration problem. I tested it for a long time and found the problem:

When spring security is used, the server is started to inject basedao queries. Because the request query is not passed, spring cannot manage the range of sessions, which is configured in Web. xml.

Opensessioninviewfilter does not work,

In fact, in addition to the two personnel roles, the role resource entity lazy loading is invalid. In addition, the system only uses the object lazy loading for request query.
