In my earlier Integration Testing with Spring and JUnit post, I discussed how to test a service bean facade with JUnit. I also posted a video, titled Testing Spring with JUnit on YouTube. In post, Spring Boot Web Application – Part 3 – Spring Data JPA, I showed how to test a Spring Data JPA […]Continue reading
Containers based deployments are rapidly gaining popularity in the enterprise. One of the more popular container solutions is Docker. Many view containers as virtual machines. They’re not. Well, kind of not. A container is a virtual walled environment for your application. It’s literally a ‘container’ inside the host OS. Thus your application works like it […]Continue reading
I’ve been playing with Docker a lot recently to deploy Spring Boot applications. Docker is very cool. I’ve been learning a lot about it. This is my unofficial Docker Cheatsheet. Use with caution! Got any tips and tricks? Comment below, and I’ll try to update this. List all Docker Images docker images -a List All Running […]Continue reading
Recently while working with Jackson within a Spring Boot project, I encountered an issue I’d like to share with you. Jackson is currently the leading option for parsing JSON in Java. The Jackson library is composed of three components: Jackson Databind, Core, and Annotation. Jackson Databind has internal dependencies on Jackson Core and Annotation. Therefore, adding […]Continue reading
When it comes to logging in enterprise applications, logback makes an excellent choice – it’s simple and fast, has powerful configuration options, and comes with a small memory footprint. I have introduced logback in my introductory post, Logback Introduction: An Enterprise Logging Framework. YAML is just one option you can use for Spring Boot configuration. […]Continue reading
In this post we will explore using Spring Boot’s default logging framework, Logback. Logback makes an excellent logging framework for enterprise applications. It’s fast, and has simple but powerful configuration options, and comes with a small memory footprint. I introduced logback in my introductory post, Logback Introduction: An Enterprise Logging Framework. In a series of […]Continue reading
Monitoring, diagnosing, and troubleshooting are key activities in any enterprise application lifecycle, and logging is the core part of these activities. Through logging you get to see what the application code is actually doing during these activities at runtime. Using System.out to print messages to the console is simply not sufficient for enterprise applications. Enterprise applications […]Continue reading
Similar to accompanying application development activities, such as unit testing and documentation, logging is an integral part of any enterprise application. And Spring Boot applications are no different. Through logging, you get to see what the Spring Boot application code is really doing during monitoring, troubleshooting, and debugging. Spring Boot makes using a logging framework […]Continue reading
Samy is my Hero A few months ago Tim Ferriss interviewed Samy Kamkar on his podcast. Samy’s large claim to fame is being the author of the MySpace Samy worm. This is a worm that infected over a million MySpace accounts in just 20 hours. MySpace actually shut down because of the worm. Hearing Samy’s […]Continue reading
Spring Boot makes it extremely convenient for programmers to quickly develop Spring applications using an in-memory database, such as H2, HSQLDB, and Derby. These databases are lightweight, easy to use, and emulates other RDBMS with the help of JPA and Hibernate. Obviously, they don’t provide persistent storage; but they a fast way to test persistent functions […]Continue reading
