The world of Java development is flooded with many powerful frameworks equipped with many fascinating approaches. A core Java beginner or a developer is always in state of confusion when it comes to upgrading their skills. Which framework to choose to get the maximum benefit within the minimum time? The Spring framework is the first answer comes into my mind. No, not because I am writing a book about it. It's the power that helps developers in every stage of development to come up with a good quality product in minimum time. Spring Framework amazingly handles standalone applications and enterprise applications. The freedom in development is secret of its success. It doesn't force developers at any stage to be bonded with APIs but allows them to use them freely. The best thing is the developers can choose their own development style to follow. They don't need to worry about XML-based or annotation-based approach.

We have tried to make the book as simple as possible so that even a first-time reader will able to explore the framework on their own. Starting from very basic things such as bean and its configuration, each chapter smoothly takes you on a very interesting journey. We aim to move on gradually from an easy to complex configurations sequentially. The current working developers who don't want to go through one-by-one may open any page and start reading. You will always find it easy to follow.

The book is just not one more book that revises the concepts in Spring. We have tried to relate each concept from the previous version and the changes that have taken place in the new version. It's more of a philosophical relation. We have tried to cover everything in the new version from the ground up. We have taken all the efforts to make the book best suitable for learners at all stages.

Just leave the worries and go for it!
