MDC or Mapped Diagnostic Context is a lighter technique consists of uniquely stamping each log request servicing a given client. To uniquely stamp…

Introduction In this tutorial I will show you how to configure log4j2 in Java, Spring and Spring Boot applications. The same log4j2 configuration will work for Java, Spring and Spring Boot applications. I am not going to show you how to use logback API in Spring Boot application, instead I will exclude logback API from…

Log4j is a logging library for Java applications and the purpose of inserting log statements into the code is a low-tech method for debugging it. It may also be the only way because debuggers are not always available or applicable. This is often the case for distributed applications.

Introduction The purpose of inserting log statements into the code is a low-tech method for debugging it. It may also be the only way because debuggers are not always available or applicable. This is often the case for distributed applications. Features of Log4j We can enable logging at runtime without modifying the application binary. We…

Introduction We will see here an example on simple log4j configuration in Java. The purpose of inserting log statements into the code is a low-tech method for debugging it. It may also be the only way because debuggers are not always available or applicable. This is often the case for distributed applications.
