GSON is a very popular Java library for work with JSON. JavaScript Object Notation (JSON) is a lightweight data exchange format. Like XML, JSON provides a way of representing object that is both human readable and machine processable. In the Java ecosystem, there are several libraries that you can use to serialize Java objects to […]Continue reading
I have met many developers who refer to tests as “Unit Tests” when they are actually integration tests. In service layers, I’ve seen tests referred to as unit tests, but written with dependencies on the actual service, such as a database, web service, or some message server. Those are part of integration testing. Even if […]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
It’s not uncommon for computers to need to communicate with each other. In the early days, this was done with simple string messages. Which was problematic. There was no standard language. XML evolved to address this and provides a very structured way of sharing data between systems. XML is so structured, but many find it […]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
Logback is designed to be faster and have a smaller memory footprint than the other logging frameworks around. If you are new to Logback, you should checkout my introductory post on Logback: Logback Introduction: An Enterprise Logging Framework. Logback supports configuration through XML and Groovy. I explained XML configuration in my previous post, Logback Configuration: using […]Continue reading
The whole purpose of logging gets defeated when the underlying logging framework becomes a bottleneck. Logging frameworks need to be fast, have a small memory footprint, and easily configurable. Logback is a logging framework with those qualities. If you are new to Logback, I suggest going through my introductory post on Logback: Logback Introduction: An Enterprise […]Continue reading
The majority of the time when you’re working with Maps in Java, you’ll be accessing the map values via the key. There are times you need to walk the map like a list. There’s a number of ways to do this in Java, which have grown over time as the language has evolved. Let’s take […]Continue reading
