What is and Why Spring Batch?

Motivation for Batch Processing

Many applications within an enterprise require bulk processing to perform business operations that include automated, complex processing of large volumes of information that is most efficiently processed without user interaction
Examples
- Time based events (e.g. month-end calculations, sending notices or correspondence on monthly basis)
- Periodic application of complex business rules processed repetitively across very large data sets (e.g. insurance benefit determination or rate adjustments)
- Integration of information that is received from internal and external systems that typically requires formatting, validation and processing in a transactional manner into the system of record

What is Spring Batch?

Lightweight, comprehensive batch framework designed to enable the development of robust batch applications
Built upon the design principles of Spring framework
- POJO-based development approach
- Ease of development
Provides reusable functions that are essential in processing large volumes of records, including
- logging/tracing
- transaction management
- job processing statistics
- job restart, skip
- resource management

One of the finest and most reasonably priced Java educational sites on the Web. All courses have been well thought out with documentation, labs and unlimited video reviews. Not to mention a support team that responses quickly to questions. I have subscribed to JPassion for the past two years and reference it almost daily.

I have done a lot of J2EE development, and moved to other Enterprise Technology space in recent years. Want to get back to serious development work and needed a refresher. I enjoyed your Spring Boot Camp. It is thorough with documentation,samples and pointers for supporting tool-set. Thank you for enabling continuous learning and also keeping it affordable for everyone.

Before taking the Spring Framework Programming (with Passion!) "Training course from Jpassion.com, I felt like Spring was too complicated for me to easily understand with out spending weeks implementing multiple spring projects, and banging my head into the wall. The training was presented covering different parts of Spring, in a way that could be easily understood, and digested. Each training session ended in a lab where you would extend the functionality of the covered material, thus cementing the material in you mind. After a few days, the stuff I had learned before started to fade, and I worried about how well I had learned the material. This is one of the best parts of jpassion.com, I could easily go to the training material, and pull down a video recording of the training session, thus it would refresh my memory on the subject, and can be used for a reference guide anytime I approach another part of spring that I was trained on. (vs in-class training, where you only have your notes to look at on.) I feel that the spring training was invaluable in my present job, and I look forward to many more training sessions! Thanks so much!!!

Whenever I've attended Sang's codecamps or his tutorials, I can't appreciate enough the efforts he makes and goes out of his way to explain the details. In today's fast times, it nice to know that you can go to a reliable mentor who can teach you the latest technologies so easily, and who is also very affordable. There are many instructors out there, but Sang stands out for his humility and passion. Thank you Sang for your great service.

Loved the way of explanation and description-code hopping style touching almost all the main topics. Hungry for more.

The codecamp is going really smooth and the presentations + labs are neat and to the point.Someone with Java experience should start getting a grasp of things quite easily.Thank you again for answering all the questions!The interaction is priceless in comparison to just reading a book

Thank you very much Sang. Even though I have used Spring in a few projects, your class always has something new and refreshing!

Inspite of that course was a bit advanced for my programming level. It was explained in easy and clear way with lots of examples and hands on exercise. It kept me on track most of the time. I peeked a lot of useful information. Mr Sang Shin is a Doctor of Instructors.He know how to explain with passion.

This is nice to see all the information at one place to start with a Spring application.

Lokesh Jain

The codecamp / course gives a great opportunity for starting development in Spring or refreshing the previous experience and getting familiarization with the features of Spring 4.x.

Excellent REST with Spring 2 day code-camp. A high speed tour through all the important stuff. Good tutorial material with clear explanations and plenty of relevant hands-on labs. Five star!

Jonathan Lister

Wonderful hands-on code camp, covers so many Rest Programming topics in detail. I have learned lots of from this class.
