Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Running BrownField services on EC2

In this section, we will set up BrownField microservices on the EC2 instances created. In this case, the build is set up in the local desktop machine and the binaries will be deployed into AWS. Follow these steps to set up services on the EC2 instance:

  1. Change all IP addresses in *.properties to reflect the IP address of the EC2 instance.
  2. Change the Java files mentioned earlier under and to reflect the IP addresses.
  1. On the local machine, recompile all projects and create Docker images for all microservices. Push all of them to the Docker Hub registry.
  2. Set up Java 8 on the EC2 instance.
  3. Execute the following commands in sequence:
sudo docker run --net=host rabbitmq:3
      sudo docker run -p 8090:8090 rajeshrv/search:1.0
      sudo docker run -p 8001:8001 rajeshrv/website:1.0
  1. Validate whether all services are working by opening the URL of the website and execute search. Note that we will be using the public IP of the EC2 instance in...
