In the beginning, I had a hundred problems creating beans, and spent hours to understand how spring works. I produce a lot of modules and libraries and separate everything by features. So, my applications don’t have a simple model-view-controller folder-set as I have hundreds or even thousands of classes in enterprise solutions. And, I was facing issues with setting up my libraries which were not in the application package in spring. By application package I mean where the Spring Application class resides in and all the sub-packages.
So, what happens when packages are outside? – the beans are not created, the spring annotations do not work! The solution is pretty easy but hard to find unless you are already familiar with “spring keywords“. But, the only way to get familiar with spring terminology is to become a master of it first! Anyway, so my goal here is to write tutorials which would be easy to find with common keywords like “my beans are not working in spring”.
