Spring #Cacheable Not Working - spring

Question

I have a dao method annotate with #Cacheable but its cache not working at all. I put log message inside the method.
<cache:annotation-driven mode="proxy" proxy-target-class="true" cache-manager="cacheManager" />
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="WEB-INF/ehcache/ehcache.xml"></property>
<property name="shared" value="true"></property>
</bean>
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager" ref="ehcache"></property>
</bean>
#Controller
#RequestMapping(value = "/analytics")
public class AnalyticsController {
#Autowired
private ReportDao reportDao;
/**

*/
public AnalyticsController() {
}
#RequestMapping(value = "/lcr-report", method = RequestMethod.GET)
public String viewCostReport(ModelMap map) {
List<Country> countryList = reportDao.getAllCountry();
map.put("countryList", countryList);
return "lcrReport";
}
}
#Repository
#Transactional(propagation=Propagation.REQUIRED, isolation=Isolation.DEFAULT,
rollbackFor={DataAccessException.class, SQLException.class, Exception.class})
public class ReportDao {
#Autowired
private JdbcTemplate dao;
/**

public ReportDao() {
}
#Cacheable(value = {"reportDao"}/*, key= "T(Country).hash(#List<Country>)"*/)
#Transactional(propagation=Propagation.REQUIRED, isolation=Isolation.DEFAULT, readOnly=true,
rollbackFor={DataAccessException.class, SQLException.class, Exception.class})
public List<Country> getAllCountry() {
List<Country> countryList = null;
BeanPropertyRowMapper<Country> mapper = new BeanPropertyRowMapper<Country>(Country.class);
PreparedStatementCreator psc = new GenericPreparedStatementCreator("select c.country_code as countryCode, c.name as countryName from country c");
System.out.println("Not from cache");
countryList = dao.query(psc, mapper);
return countryList;
}
}

Answer 1

You should create key by using parameters to method getAllCountry. In your case it is empty, so you can do like this:
#Transactional(readOnly = true)
#Cacheable(value = CACHE_NAME, key = "'countries'")
and check if it works using Map cache:
#Configuration
#EnableCaching(proxyTargetClass = true)
public class CacheProducer {
#Bean
public CacheManager cacheManager() {
SimpleCacheManager result = new SimpleCacheManager();
result.setCaches(Arrays.asList(new ConcurrentMapCache(DictionaryServiceImpl.CACHE_NAME)));
return result;
}
}
If it works - it is time to check your echache config.
