Hi,
I am using IBatis-3 build 242 (the latest available on the website) and I
find that though I set a cache policy, there is no caching being done by
IBatis.
In my mapper XML file I have the following line for cache configuration.
<cache eviction="LRU" size="200000" readOnly="true" flushInterval="300000"/>
I have a function getStrategies() as seen below.
List<Strategy> getStrategies() {
final SqlSession session = sessionFactory.openSession();
try {
final StrategyMapper stratMapper = session.getMapper(
StrategyMapper.class);
return stratMapper.getStrategies();
} finally {
if (session != null) {
session.close();
}
}
}
In my unit tester, I call the getStrategies() method in a loop. For every
call to getStrategies(), I get the following log message when I turned on
DEBUG logging.

I am not sure why caching is not working. Please correct me if I am using
the caching mechanism incorrectly.
Thanks,
Gesly
