问题
I'm using JPA2.1 and hibernate 4.3.8 and i have configured the presistence.xml to allow lazy loading
i have added
<property name="hibernate.enable_lazy_load_no_trans" value="true" />
into properties section
but i'm still getting LazyInitializtionException, what is the problem ?
回答1:
The hibernate.enable_lazy_load_no_trans is an anti-pattern and you should never use it because a database connection is needed for every lazy association that is fetched outside of the initial Persistence Context, and that's going to put pressure on the underlying transaction log and the JDBC connection pool.
More, the hibernate.enable_lazy_load_no_trans is prone to N+1 query issues.
Sometimes, you don't even need entities, and a DTO projection is even better.
回答2:
Try enter the "true" like this:
<property name="hibernate.enable_lazy_load_no_trans">true</property>
It work for me.
