parser service interface:

}
and parser implementation:
public class ParserServiceImpl implements ParserService {
private static final Logger logger = LoggerFactory
.getLogger(HomeController.class);
public ParserServiceImpl() {
}
#Override
#Cacheable(value="myData")
public List<Data> parse() {
List<Data> dataList = new ArrayList<Data>();
Data data= (Data) new Finder().getData(0);
dataList.add(data);
logger.info("data is not cached");
}
return dataList;
}

I think you need to implement serializable class for your Data(POJO). and I don't know why didn't you have cache.xml. Please refer this https://mytechrepo.wordpress.com/2015/07/23/caching-data-with-spring-3-1-1-and-ehcache-demo/
