Mastering Spring Boot 2.0

By: Dinesh Rajput

Overview of this book

Spring is one of the best frameworks on the market for developing web, enterprise, and cloud ready software. Spring Boot simplifies the building of complex software dramatically by reducing the amount of boilerplate code, and by providing production-ready features and a simple deployment model. This book will address the challenges related to power that come with Spring Boot's great configurability and flexibility. You will understand how Spring Boot configuration works under the hood, how to overwrite default configurations, and how to use advanced techniques to prepare Spring Boot applications to work in production. This book will also introduce readers to a relatively new topic in the Spring ecosystem – cloud native patterns, reactive programming, and applications. Get up to speed with microservices with Spring Boot and Spring Cloud. Each chapter aims to solve a specific problem or teach you a useful skillset. By the end of this book, you will be proficient in building and deploying your Spring Boot application.

Summary


Testing is an essential part of any development. Unit testing tests a class in isolation and external dependencies should be minimized. You can consider creating stubs or mocks to unit test. You don't need Spring to unit test. Integration testing tests the interaction of multiple units working together. Spring provides good integration testing support and profiles for different test and deployment configurations.

There are many tools available to test services such as Postman and SoapUI. In this chapter, we saw how to use Postman to test RESTful services. Postman provides support for all HTTP methods with every content type.

In the next chapter, we will explore the Docker container and will create Docker images.
