LazyInitializationException() about spring-data-rest HOT 5 CLOSED

The OpenEntityManagerInViewInterceptor is supposed to make sure a session is open until the object is rendered, but maybe the way it's set up currently isn't catching this case.

Let me ask some of the other data guys and see what they think...

from spring-data-rest.

Can we get a fuller stacktrace? I need to see where this is occurring specifically within the lifecycle of the exporter.

I will send it to you via email!

I suspect this is due to OpenEntityManagerInViewInterceptor not being registered in the MVC HandlerAdapater. Until I get a fix for that in master, you might try adding back in the OpenEntityManagerInViewFilter that was in there originally:

<filter>
  <filter-name>entityManagerInViewFilter</filter-name>
  <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
</filter>

<filter-mapping>
  <filter-name>entityManagerInViewFilter</filter-name>
  <servlet-name>exporter</servlet-name>
</filter-mapping>

from spring-data-rest.

Adding this results in:
