Extending, Securing, and Dockerizing Spring Boot Microservices

Build on your foundational knowledge of Spring. Learn how to extend, secure, and "dockerize" Spring Boot microservices, and turn them into production-ready applications.

Introduction

• Elevate a microservice
• What you should know
• Reviewing the Original Spring Boot microservice

1. Enhancing a Spring Boot Microservice

• Running the microservice
• Define the schema and default data
• Identify transactional business services boundaries

2. Hardening the Microservice

• Adding a runtime logger
• Unit testing with Mockito vs. integration testing
• Restful API testing with JUnit
• Documenting APIs with Swagger

3. Spring Security with JSON Web Tokens (JWT)

• Users and roles
• Spring Security authentication
• Password encryption
• Understanding JWT
• Configuring Spring Security for JWT for authorization
• Securing APIs

4. Leveraging Docker for MySQL Database Access

• What is Docker?
• Running the application with MySQL container
• Database migration with Flyway
• Selecting Spring profiles at runtime

5. Dockerizing Your Microservice

• Create and run a Java application Docker image
• Link the Java application and database Docker containers
• Separate application image from database migration
• Leverage a Docker Maven plugin
• Sharing images with Docker hub
