问题:

Oracle Coherence states that it is "JCache-compliant". How can I take my code written against JSR-107, specifically the ehcache-jcache jar, and run it against Oracle Coherence?

回答1:

Final JCache APIs are expected to be released in summer/fall 2013. Then you can expect to see those final APIs supported in Coherence.

Update (14 February 2014) - As soon as we check off some legal check-boxes, the APIs & RI & TCK are all ready to be submitted for approval, and the next version of Coherence (version 12.1.3) will include & support the final APIs.

Update (11 July 2014) - The JCache standard is done and out, and Coherence now officially supports the JCache standard; see the documentation at: http://docs.oracle.com/middleware/1213/coherence/develop-applications/jcache_part.htm

回答2:

The ehcache-jcache jar is a specific implementation of JSR-107. Coherence is not binary compatible with that implementation. Coherence is compliant with the interfaces specified in JSR-107 but provides its own implementation.

Coherence offers a huge number of features beyond JSR-107, so it would be overkill to use it just for JSR-107.
