Spring data - modifying queries and ehcache (cache)

Question

Is it possible to make spring data modifying query such as:

@Modifying
@Query("update User u set u.firstname = ?1 where u.lastname = ?2")
int setFixedFirstnameFor(String firstname, String lastname);

Auto invalidate my ehcache of User entity?

Thanks!

Answer 1

Yes it is possible if you declare the User entity as cached using for example a READ_WRITE cache concurrency strategy:

@org.hibernate.annotations.Cache(usage=CacheConcurrencyStrategy.READ_WRITE)
public class User {
    ...
}

In such case the cache invalidation will be taken care automatically by Hibernate.

Answer 2

Have a look at the Spring Cache abstraction documented here . It basically allows you to configure what to cache/evict where and completely configure which cache provider to be used in your application configuration.

Note, that this will cache on the annotated method level.
