You can read more about how to use it for logging Java applications from our Log4j 2 tutorial. If you are starting a new project and you are looking for a library of choice Log4j 2 should be the main focus. It incorporates lots of improvements over its predecessor and promises to provide Logback improvements while fixing issues with some of its architectural problems. Log4j 2 is the newest in the list of all the mentioned Java logging frameworks. If you are still using this framework, check out our Log4j tutorial where we go over its functionality.
Log4j reached its end of life on 5th of August 2015 and users are recommended to use Log4j 2. Log4j is one of the most widely known Java logging libraries and the predecessor for such projects as Logback or Log4j 2. If this is your framework of choice, check out our Logback tutorial where we go over how it works and how to configure it for logging Java applications. It is built out of three main modules and integrates with Servlet containers such as Tomcat or Jetty to provide HTTP-access log functionality. Logback started as an intended successor to the first version of the Log4j project claiming faster implementation, better tests, native SLF4J integration, and more. It comes bundled with the Java Development Kit and is available for every developer using Java since Java 1.4. The package provides the classes and interfaces for Java core logging facilities. In our SLF4J tutorial, we explain everything there is to know about the abstraction layer so that you can log easier and smarter. If you’re new to SLF4J, we have just the blog post for you. This enables quick and easy change of logging framework of choice when it is needed. The Simple Logging Facade for Java or simply SLF4J is an abstraction layer for various logging frameworks allowing us, as users, to choose the logging framework during the deploy time, rather than during the development time. Let’s get started! Java Logging Frameworks SLF4J Out of the box Java logging capabilities.

In this blog post, we will focus on how to properly set up logging for your code to avoid all those mistakes that we already did. Sounds complicated? It doesn’t have to be. This can come in handy if you ever need to replace your logging library for whatever reason – for example performance, configuration, or even simplicity. On top of that, there are also abstraction layers that enable easy switching of the underlying framework without the need of changing the implementation. There are frameworks for Java that provide the object, methods, and unified configuration methods that help setting up logging, store logs, and in some cases even ship them to a log centralization solution. Logging in Java could be done just by easily writing data to a file, however, this is not the simplest or most convenient way of logging. Today, we’re going to focus on your Java application logs. To fully understand the environment you also need Java logs and traces. When it comes to troubleshooting Java application performance, JVM metrics are no longer enough.
