Build Spring Microservices and Dockerize Them for Production
In this post, you’ll learn about microservices architecture and how to implement it using Spring Boot. After creating some projects with the technique, you will deploy the artifacts as Docker containers and will simulate a container orchestrator (such as Kubernetes) using Docker Compose for simplification. The icing on the cake will be authentication integration using Spring Profiles; you will see how to enable it with a production profile. But first, let’s talk about microservices. Understand...
Spring Boot with PostgreSQL, Flyway, and JSONB
In this tutorial, you are going to learn more about PostgreSQL and how to integrate it with a Spring Boot application. You will learn how to install a simple PostgreSQL instance using Docker and how to connect a Spring Boot application to it. After that, you’ll create a simple database schema and add some data to it. Next, I’ll show you how to create SQL files to deliver database changes, which are more suitable for...
Data Persistence with Hibernate and Spring
Java developers typically encounter the need to store data on a regular basis. If you’ve been developing for more than 15 years, you probably remember the days of JDBC in Java. Using JDBC can be tedious if you don’t like writing SQL. Not only that, but there’s nothing in JDBC that helps you create your database. Hibernate came along and changed everything by allowing you to map POJOs (plain ol’ Java objects) to database tables....
