[Hibernate] one cause of LazyInitializationException

Sometimes a LazyInitializationException will be thrown on getHibernateTemplate().load().

Reason being when using load(), Hibernate simply retrieves you a Proxy, which has only the id set, rest of the fields being queried from database when needed. At that time, the hibernate session might have been closed.

A quick fix: replace .load() with .get(). It'll fetch the result immediately.

简直扯淡，get和load都报同样的错！
