clear hibernate cache of specific domain class

Question

Imagine i have following class:

class Test {
   String name    
   static mapping = {
      cache true
      version false
}

The goal would be to insert rows using native sql on the database level so hibernate wouldn't recognize those changes. how can i notifiy hibnerate about this new rows?

Is there something like -> Test.clearCache?

Answer 1

This answer is a little bit old... the evict method is deprecated... you can use

sessionFactory.cache.evictEntityRegion(Class.name)

this worked for me... just google the class and you will find all methods...

Answer 2

Though it's a deprecated way, it's shorter and still works.

def sessionFactory // inject Hibernate sessionFactory
sessionFactory.evict(clazz, id)
// or evict all class instances:
sessionFactory.evict(clazz)

Documentation is here, see it for the up-to-date way with Cache.
