How do I set up Log4j for error tracking in my application?

To set up Log4j, first, include the Log4j library in your project. You can do this by adding the dependency in your build file.

What dependencies do I need to add?

If you're using Maven, add this to your pom.xml: <dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-core</artifactId><version>2.x.x</version></dependency>.

How do I configure the logging properties?

Create a log4j2.xml file in your resources folder. Define your loggers, appenders, and log levels there.

Can you give me an example of a log4j2.xml configuration?

Sure! Here's a simple example:

<Configuration>
  <Appenders>
    <Console name="Console" target="SYSTEM_OUT">
      <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %p %c{1} - %m%n"/>
    </Console>
  </Appenders>
  <Loggers>
    <Root level="info">
      <AppenderRef ref="Console"/>
    </Root>
  </Loggers>
</Configuration>
