Video description

This video course offers a comprehensive overview of developing both SOAP and RESTful web services using Spring Boot, Spring Web MVC, Spring Web Services, and JPA. The course begins with an introduction to the basics of RESTful web services and their significance in a microservices architecture.

The course is divided into two parts: RESTful web services and SOAP web services. In the first part, you will learn the fundamentals of RESTful web services by developing resources for a social media application. You will explore various features such as versioning, exception handling, documentation (Swagger), basic authentication (Spring Security), filtering, and HATEOAS, along with best practices in designing RESTful web services.

Throughout the course, you will be working with various tools and frameworks, such as Spring (dependency management), Spring MVC (or Spring REST), Spring Boot, Spring Security (authentication and authorization), Spring Boot Actuator (monitoring), Swagger (Documentation), Maven (dependencies management), Eclipse (IDE), Postman (REST services client), and the Tomcat embedded web server.

By the end of the course, you will have a solid understanding of how to develop both SOAP and RESTful web services using Spring and be able to apply these skills to real-world projects.

What You Will Learn

  • Design resources and execute GET, POST, and DELETE operations
  • Implement validation for RESTful web services
  • Handle exceptions in RESTful web services
  • The concept of HATEOAS and how to implement it for a resource
  • Different approaches to versioning RESTful services
  • Use Postman to make requests to RESTful services

Audience

If you are looking to acquire a foundational understanding of web services and associated terminology and want to learn how to develop and design RESTful and SOAP web services, this course is perfect for you. Whether you are an experienced Java developer seeking to expand your skills, or a Spring expert looking to leverage your knowledge, this course has everything you need to take your web services proficiency to the next level.
