[NEW] Spring Framework 6: Beginner to Guru

This course is All Things Spring!

Do you wish to master Spring Framework 6 and Spring Boot 3? Then this is the course for you.

This course is for developers with no previous Spring Framework or Spring Boot experience.

You will master developing RESTful APIs with Spring Framework. Spring has three different options of creating RESTFul APIs: Spring MVC, Spring WebFlux, and Spring WebFlux.fn. You will see how to use each, and how to secure each using OAuth 2.0 with JWT.

Also covered in the course are popular persistence technologies. You will learn to use Spring Data JPA with Hibernate, Spring Data MongoDB, and Reactive with Spring R2DBC.

All examples in the course use Java 21 and Spring Boot 3.3.0.

Inside this course, you will learn about:

• Build a Spring Boot Web App

• Use Spring for Dependency Injection

• Create RESTful Web Services with Spring MVC

• Create RESTful Web Services with Spring Webflux

• Create RESTful Web Services with Spring Webflux.fn

• June 2024 – Using Spring Boot with Docker, Docker Compose and Kubernetes

Spring Core

At the core of the Spring Framework is the Spring IoC Container. Inversion of Control is a design pattern where control is inverted compared to procedural programming. In procedural programming, the software calls reusable components to complete tasks. In contrast, with IoC it is the framework which calls the reusable libraries. Development with IoC becomes very efficient since the focus is more on the custom business logic and common logic is left to the framework to perform.

Spring MVC

SpringMVC is Spring Framework’s original web application framework. Spring MVC implements the model-view-controller design pattern, where a model (data) is shared with with a controller which presents the data to the end user in the view (HTML, JSON, XML, etc).  In this course you will learn how to develop RESTful APIs using Spring MVC.

Spring Webflux

Spring Webflux was introduced to the Spring Framework in version 5. Spring Webflux is a reactive web application framework using non-blocking Java components for building efficient and scalable web applications.  Like Spring MVC, Spring Webflux also implements the model-view-controller design pattern. Spring Webflux closely follows the familiar syntax of Spring MVC. In this course you will learn to use Spring Webflux to create modern RESTful APIs.

Spring Webflux.fn

Spring Webflux.fn was also introduced in Spring Framework version 5. Spring Webflux.fn follows a functional programming paradigm. Through the use of functional programming, you can rapidly develop API endpoints. In this course you will learn how to use the functional programming paradigm of Spring Webflux.fn to develop RESTful APIs.

Spring Data

Spring Data is a family of Spring Framework projects for persistence operations to SQL and NoSQL databases. The Spring Data projects implement the easy to use Repository Pattern to persist objects to the database. In this course you will see how to use Spring Data JPA for persistence with SQL databases, how to use Spring Data Mongo for persistence to the NoSQL Mongo Database, and how to use Spring Data R2DBC for reactive/non-blocking SQL database persistence.

Spring Security

Spring Security is commonly used to secure Spring Framework applications. You will see how simple it is to use Spring Security for HTTP Basic authentication. You will also learn how to use Spring Security with OAuth 2.0 authentication.

Spring Authorization Server is a recent addition to the Spring Framework family of projects. Spring Authorization server is a lightweight alternative to other identity providers, such as Keycloak. You will learn to implement the OAuth 2.0 Client Credentials flow to obtain a JWT authorization token from the Spring Authorization Server and how to configure RESTful APIs in Spring MVC, Spring Webflux, and Spring Webflux.fn as OAuth 2 Resource Servers.

Spring Rest Clients

Spring Framework 6 now has 3 different rest clients which may be used to interact with RESTful APIs.

Spring RestTemplate was originally was introduced in Spring Framework version 3. You will learn to use Spring RestTemplate to authenticate with OAuth 2.0 and interact with RESTful APIs.

Spring WebClient was introduced in Spring Framework version 5. Spring WebClient is a reactive/non-blocking rest client. Like Spring Webflux.fn, Spring WebClient uses an efficient fluent API. In this course you will learn to use Spring WebClient to authenticate with OAuth 2.0 and interact with RESTful APIs.

Spring RestClient is the latest Rest Client for the Spring Framework. Spring RestClient was introduced to the Spring Framework with Spring Framework 6.1 in November of 2023. Spring RestClient uses the same synchronous libraries as Spring RestTemplate. But Spring RestClient uses the same functional API as Spring WebClient. You will learn to use Spring RestClient to authenticate with OAuth 2.0 and interact with RESTful APIs.

Spring Boot

Spring Boot was added to the Spring Framework family of projects in 2014. Spring Boot brings sensible ‘convention over configuration’ to the Spring Framework. Spring Boot helps minimize configuration tasks by providing an opinionated configuration through the use of Spring Boot starters. For many 3rd party libraries, Spring Boot will automatically provide sensible defaults and configuration of components.

Spring Boot also provides production-ready features such as metrics, health checks and externalized configuration.

Docker with Spring Boot

A very common way to deploy Spring Boot applications is to use Docker containers. You will see how easy it is to use the Spring Boot Maven plugin to generate a Docker image for your application. Once the image is created, you can run the image in a Docker container. You will learn the Docker commands to start 5 different Spring Boot applications.

Docker Compose with Spring Boot

Docker Compose is a tool for running multi-container applications. You will learn how to start the 5 Spring Boot Applications you build in this course, plus how to run MySQL and Mongo DB inside of a Docker network. Spring Cloud Gateway is used to control ingress to the RESTful Spring Boot services running in side the Docker network.

Kubernetes with Spring Boot

Kubernetes is a popular container orchestration platform. Originally developed by Google, Kubernetes is being adopted by companies all over the world. Using the same applications you learned to deploy with Docker and Docker Compose, you will learn how to deploy them in a Kubernetes context.
