Spring 5.0 By Example: Grasp the fundamentals of Spring 5.0 to build modern, robust, and scalable Java applications review

Discover the real power of Spring Framework 5.0 and learn to create powerful applications in its newest version

Key Features

• Learn reactive programming by implementing a reactive application with Spring Webflux
• Create a robust and scalable messaging application with Spring messaging support
• Apply your knowledge to build three real-world projects in Spring

Book Description

With growing demands, organizations are looking for systems that are robust and scalable. Therefore, the Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring.

The book has three parts, where each one covers the building of a comprehensive project in Java and Spring. In the first part, you will construct a CMS Portal using Spring's support for building REST APIs. You will also learn to integrate these APIs with AngularJS and later develop this application in a reactive fashion using Project Reactor, Spring WebFlux, and Spring Data. In the second part, you’ll understand how to build a messaging application, which will consume the Twitter API and perform filtering and transformations. Here, you will also learn about server-sent events and explore Spring’s support for Kotlin, which makes application development quick and efficient. In the last part, you will build a real microservice application using the most important techniques and patterns such as service discovery, circuit breakers, security, data streams, monitoring, and a lot more from this architectural style.

By the end of the book, you will be confident about using Spring to build your applications.

What you will learn

• Implement REST APIs with Spring REST support
• Introduce the Spring Boot and understand how it makes creating robust applications extremely simple
• Understand how Spring Data helps us add persistence in MongoDB and SQL databases

Building RESTful Web Services with Spring 5 - Second Edition: Leverage the power of Spring 5.0, Java SE 9, and Spring Boot 2.0 review

Find out how to implement the REST architecture to build resilient software in Java with the help of the Spring 5.0 framework.

Key Features

• Follow best practices and explore techniques such as clustering and caching to achieve a reactive, scalable web service,
• Leverage the Spring Framework to quickly implement RESTful endpoints,
• Learn to implement a client library for a RESTful web service using the Spring Framework along with the new front end framework.

Book Description

REST is an architectural style that tackles the challenges of building scalable web services. In today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs.The depth, breadth, and ease of use of Spring makes it one of the most attractive frameworks in the Java ecosystem. Marrying the two technologies is therefore a very natural choice.This book takes you through the design of RESTful web services and leverages the Spring Framework to implement these services. Starting from the basics of the philosophy behind REST, you'll go through the steps of designing and implementing an enterprise-grade RESTful web service. Taking a practical approach, each chapter provides code samples that you can apply to your own circumstances.This second edition brings forth the power of the latest Spring 5.0 release, working with MVC built-in as well as the front end framework. It then goes beyond the use of Spring to explores approaches to tackle resilience, security, and scalability concerns. Improve performance of your applications with the new HTTP 2.0 standards. You'll learn techniques to deal with security in Spring and discover how to implement unit and integration test strategies.Finally, the book ends by walking you through building a Java client for your RESTful web service, along with some scaling techniques using the new Spring Reactive libraries.

What you will learn

• Deep dive into the principles behind REST
• Expose CRUD operations through RESTful endpoints with the Spring Framework
• Devise response formats and error handling strategies, offering a consistent and flexible structure to simplify integration for service consumers
• Follow the best approaches for dealing with a service's evolution while maintaining backward compatibility

• Comply with the best ways to test RESTful web services, including tips for load testing
• Optimise and scale web services using techniques such as caching and clustering

Who This Book Is For

This book is intended for those who want to learn to build RESTful web services with the latest Spring 5.0 Framework. To make best use of the code samples included in the book, you should have a basic knowledge of the Java language. Previous experience with the Spring Framework would also help you get up and running quickly.

• Develop applications by taking advantage of the latest versions of CDI, Security, Servlets, and JSF and other Java EE specifications

Book Description

Java EE is an Enterprise Java standard. Applications written to comply with the Java EE specification do not tie developers to a specific vendor; instead they can be deployed to any Java EE compliant application server. With this book, you'll get all the tools and techniques you need to build robust and scalable applications in Java EE 8. This book covers all the major Java EE 8 APIs including JSF 2.3, Enterprise JavaBeans (EJB) 3.2, Contexts and Dependency Injection (CDI) 2.0, the Java API for WebSockets, JAX-RS 2.1, Servlet 4.0, and more.

The book begins by introducing you to Java EE 8 application development and goes on to cover all the major Java EE 8 APIs. It goes beyond the basics to develop Java EE applications that can be deployed to any Java EE 8 compliant application server.
