Back Again, Weekly Readings - Week Ending 8 July 2016

It's been a long long time since I wrote a post here. A lot of changes and obstacles were around but I'm planning to get back to focusing on writing here again. I also have some plans that I'm currently working to present more useful subjects in a more interactive way like going for YouTube videos.
Well, let's warm up and start with sharing some useful readings as articles and books that I have recently checked and I believe they would spot on new subjects or discuss useful ones.

Assume we have a client and a service that would be used by the client. We pass the service to the client rather than allowing the client to build it. DI is commonly related to a wide known taxonomy which is Inversion of control aka IoC. But simply, IoC is a more general than the DI. IoC means letting the other code call you rather than insisting od doing the calling.
All of this is managed through the Spring Container which requires some sort of configurations that are presented through XML-based configuration or Annotation-based configuration. We will focus on the Annotation-based one in the below subjects.
2. Maven Configuration We need to make sure that Spring core and JUnited dependencies exists in our pom.xml
