The @Cacheable annotation of Spring works like magic, allowing us to create caches easily with just one line of code.
But it is important to not that the caching will NOT work if you are calling method is in the same class !
This happens because Spring injects a proxy at runtime to implement caching and if you are making calls to cacheable methods from the same class, the proxy is not used.
