Sherwin John Calleja Tragura started his career as a student assistant and a mathematics tutor during his college years at the University of the Philippines Los Baños, Laguna, Philippines. With meager resources, he graduated as a Department of Science and Technology (DOST) R.A. 7687 scholar under the Bachelor Of Computer Science degree. Immediately after graduation, he took up the offer to teach CMSC 150 (numerical and symbolic computation) at the Institute of Computer Science and completed his master's degree in computer science simultaneously. He became part of the International Rice Research Institute (IRRI) software team, which gave him the opportunity to use Struts, Spring, and RCP frameworks in many of its software projects.

Based on his experience at IRRI, he was given an opportunity to work as a Java analyst in various companies in Manila, such as ABSI, PHILAM- AIG, and Ayala Systems and Technology Inc. (ASTI). These companies have strengthened his skill set through training in Java and Java Enterprise platforms and some popular tools such as EMC Documentum, Alfresco Document, and Records Management System. He got his first career certification in the EMC Documentum Proven Associate course (E20-120).

After a few years, he decided to become an independent consultant and trainer, providing services mostly for Java-based projects, Alfresco, and Apache OFBiz requirements. He started his venture as a Java-JEE Bootcamp with 77Global and is currently a trainer at Software Laboratory Inc. (SLI), Alibata Business and Technology Services Inc. and Nityo Infotech, Philippines. He also conducts training and talks around the Philippines, for instance, in Cebu City and Tacloban City.

Sherwin has contributed as a technical reviewer to various books by Packt Publishing, including Delphi Cookbook, Alfresco 3 Records Management, Alfresco Share, and Mastering Hibernate. He owes everything to Packt Publishing with the unforgettable experience in the technical reviewing tasks, which have been an essential part of his career.

As an Oracle Certified Associate and Java SE 7 Programmer (1Z0-803), Sherwin will continue his mandate as a technical trainer, developer, architect, and designer to help the industry improve its standards in information technology. He will always be an epitome of honor, excellence, and service when it comes to software development and business intelligence.

The Spring framework has been the go-to framework for Java developers for quite some time. It enhances modularity, provides more readable code, and enables the developer to focus on developing the application while the underlying framework takes care of transaction APIs, remote APIs, JMX APIs, and JMS APIs.

The upcoming version of the Spring Framework has a lot to offer, above and beyond the platform upgrade to Java 9, and this book will show you all you need to know to overcome common to advanced problems you might face.

Each recipe will showcase some old and new issues and solutions, right from configuring Spring 5.0 container to testing its components. Most importantly, the book will highlight concurrent processes, asynchronous MVC and reactive programming using Reactor Core APIs. Aside from the core components, this book will also include integration of third-party technologies that are mostly needed in building enterprise applications.

By the end of the book, the reader will not only be well versed with the essential concepts of Spring, but will also have mastered its latest features in a solution-oriented manner.
