Java Logging Frameworks: The Complete Guide

This free online course will help you gain an understanding of java logging frameworks that will simplify logging.

Publisher: Quaatso
All software application requires consistency of their runtime behavior for debugging of issue, analysis and audit. How do we achieve this without having to write extra code? By taking this course, you'll learn the standard method and procedure to log anything without having to write extra code using Java logging frameworks. We'll show you various open-source logging frameworks for Java such as JUL, Log4j, Logback and SLF4j and how to use them.

Logging is the process of recording the different states of software during its execution and is an important feature that helps developers and programmers to trace out and analyze errors in Java. This course covers the basics of java logging including how to create logs and the common logging frameworks in use today. The course begins by introducing you to logging, its benefits and its usage. You will learn about the problems associated with consoles, the flow of the logging process, logging levels, loggers and more. Furthermore, you will study the objects of the in-built java API such as handlers, formatters, filters and hierarchy. Discover the different types of handlers that exist in Java Util Logging (JUL) and use them to receive messages from a logger to a target. Moving on from there, we will show you how to format log messages and set log levels to filter out log messages. 

Logging in Java often requires using one or more logging frameworks. These frameworks provide the objects, methods, and configuration necessary to create and send log messages to a target like consoles, files, or a database. There are many third-party frameworks that can be used to achieve this. These frameworks (the most common) include but are not limited to log4j, slf4j and logback. Which logging framework should you use? Choosing a logging framework depends on a number of factors such as the available functionalities of the framework, the complexity of your logging needs, ease of use, and personal choice. In this course, you will gain an understanding of log4j, its benefits and advantages over the in-built java API. Learners will explore the features of log4j as well as its handler implementations. On top of that, you will be shown how to configure log4j in order to publish your logs in the console or any other target as well as how to add dependency of log4j to a project. 

Next, you will explore the appenders associated with log4j, and different appender implementations given by log4j. Learners will also gain a deep understanding of log4j layouts and its uses. What do you do when you need to change from one logging framework to another in real-time? Instead of the direct use of a particular framework. A standard interface gives us the flexibility of switching to any of the frameworks at any point in time instead of the direct use of a particular framework at all times. This is where slf4j comes into play. Discover how to use slf4j and its binding implementation. Some projects in Java demand quick execution and this course will teach you about the fastest logging framework (logback) as well as its essential functions such as installation, log capture and execution. Basic knowledge of the Java programming language, a computer with any OS and Java is required for this course. This course is important for developers, programmers, college students, project managers and freshers who want to broaden their knowledge and increase their scope in the Java programming language.
