[infinispan-issues] [JBoss JIRA] (ISPN-7224) Support synchronous get in Spring's cache abstraction

[Mike Noordermeer (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-7224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13393019#comment-13393019 ] 

Mike Noordermeer commented on ISPN-7224:
----------------------------------------

I think lightweight locking should be fine, it is mainly about avoiding concurrent execution on concurrent cache hits, not so much about real atomicity.

This is our solution in the meantime, seems to work: https://gist.github.com/MikeN123/192f0befc17a6efd1881ae3523f669dc

> Spring Framework 4.3 has introduced a read-through option See https://jira.spring.io/browse/SPR-9254 for more details. In practice this would require you to compile against 4.3 and implement the additional method. 
> The code is meant to be backward compatible with previous version, as long as you're guarding the new exception in an inner class, see [this implementation for an example|https://github.com/hazelcast/hazelcast/blob/37ba79c4a8d35617c5f6a770eec3705f2852f938/hazelcast-spring/src/main/java/com/hazelcast/spring/cache/HazelcastCache.java#L162-L168]
> Let me know if I can help.
