Checks

Jacoco/cobertura code coverage, pmd, checkstyle, enforcer, findbugs

Structure

org.caching.autovalue contains example with builder, equals, hashcode, getters, setters example without much flexibility
org.caching.lombok contains examples with Lombok features. In IDE plugins for Lombok are needed. Main features: getters, setters, equals, hashcode, builder, lazy getter, sneakyThrows, synchronized, logger code generation.
Ehcache2TransactionDaoTest test for direct usage of ehcache version 2 with spring
JbossCacheTransactionDaoTest test with Jboss cache usage
JCacheEhCache2TransactionDaoTest jcache standard protocol with Ehcache 2 version as an implementation Use getClass().getClassLoader().getResourceAsStream("filename") instead of full path to file (like: scr/main/resources/filename) which is not a case in jar file
JCacheEhCache3TransactionDaoTest jcache standard protocol with Ehcache 3 version as an implementation with spring (no spring configuration for direct usage of ehcache 3 yet).
JCacheHazelcastTransactionDaoTest jcache standard protocol with Hazelcast as an implementation
SpringCacheTransactionDaoTest test for spring simple cache usage Tests show saving to cache / without cache and reading the values. With Cache look ups are quicker. Evict does nothing, cause small data. Clearing cache shows that cache is not hit in this case.
GuavaCacheTest test Guava abilities to cache

Building project

mvn clean package

Coverage

Excluded some auto generated classes from cobertura and coveralls coverage for lombok and autovalue cause they do not support it well

Pom.xml

Libraries:

hazelcast
ehcache 2
ehcache 3
jboss cache
jcache
guava
spring
lombok
autovalue
log4j logging (possibility to configure) via slf4j
