Overview of this book

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.

Running the Redis instance


The image was downloaded, then we will start the Redis instance for our application. The command can be:

docker run -d --name redis --net twitter -p 6379:6379 redis:4.0.6-alpine

We have interesting attributes here. We named our Redis instance with redis, it will be useful for running our application in containers in the next chapters. Also, we exposed the Redis container ports to the host machine, the command argument used for that is -p. Finally, we attached the container to our Twitter network.

Good, the Redis instance is ready to use. Let's check out the Spring Data Reactive Redis stuff.

Configuring the redis-cli  tool

There is an excellent tool to connect with the Redis instance which is called redis-cli. There are some Docker images for that, but we will install it on our Linux machine.

To install it, we can execute the following command:

sudo apt-get install redis-tools -y

Excellent, now we can connect and interact with our Redis container. The tool can perform the...
