WHAT OUR LEARNERS ARE SAYING

5 STARS – This is the best course if you like to learn how REST API exactly works. The instructor is awesome. I had a great time watching his videos and doing coding for this course. It really helped me to do a coding assessment for the company.

5 STARS – This course gave me an excellent head start with creating Restful web services!

5 STARS – It is such an awesome course, I have now got an idea to create production level restful services

5 STARS – As an experienced JEE developer unfamiliar with Spring Boot and developing web services within it, this was simply an awesome course for becoming knowledgeable and comfortable in applying it in a real-world context.

5 STARS – This is my first spring boot course. I’ve thoroughly enjoyed it. Thank you very much Ranga for delivering such a high quality course. I’ve learned a lot spring boot from you. If someone want to learn spring boot, this is one of the best courses to pick up.

******* Course Overview *******

Developing SOAP and RESTful web services is fun. The combination of Spring Boot, Spring Web MVC, Spring Web Services and JPA makes it even more fun.

Architectures are moving towards microservices. RESTful web services are the first step to developing great microservices. Spring Boot, in combination with Spring Web MVC (also called Spring REST) makes it easy to develop RESTful web services.

There are two parts to this course – RESTful web services and SOAP Web Services.

In the first part of the course, you will learn the basics of RESTful web services developing resources for a social media application. You will learn to implement these resources with multiple features – versioning, exception handling, documentation (Swagger), basic authentication (Spring Security), filtering and HATEOAS. You will learn the best practices in designing RESTful web services.

You will be using 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 Tomcat Embedded Web Server. We will help you set up each one of these.

While the use of SOAP Web Services is on the way down, there are still considerable number of web services using this approach.

In the second part of the course, you will learn the basics of implementing SOAP Web Services developing a few web services for a course management application. You will learn to use a Contract first approach – defining XSD (XML Schema Definition) for your requests and responses. You will learn about WSDL (SOAP Header, SOAP Body and SOAP Fault), XSD (XML Schema Definition) and JAXB (Java API for XML Binding). You will implementing three SOAP web services with exception handling and basic security (with WS Security).

In this part of the course, you will be using Spring (Dependency Management), Spring Web Services , Spring Boot, Spring Security (Authentication and Authorization), Maven (dependencies management), Eclipse (IDE), Wizdler (SOAP Services Chrome Plugin) and Tomcat Embedded Web Server. We will help you set up each one of these.
