Logging is one of those things you don’t think much about—until something breaks. Then, suddenly, logs are your best friend. If you’ve worked on Java applications, you’ve probably heard of Apache Log4j . But what exactly is it, and why does it matter? Maybe you’ve struggled with messy log files, had trouble debugging an issue in production, or heard about Log4Shell , the security vulnerability that shook the internet. Whatever the case, this tutorial will walk you through Apache Log4j —from installation to best practices—so you can log like a pro. Let’s dive in. Check out my article on  Apache Camel Tutorial with Spring Boot What is Apache Log4j ? Apache Log4j is a Java-based logging library used to track application activity. Instead of using System.out.println() all over your code (which gets messy fast), Log4j gives you a structured way to log messages, filter them, and control where they go (console, files, databases, etc.). But here’s what makes Log4j special: ✔ Customizable...
