How To Set Up Logs with Rolling File Appender

This guide will help you to set up a rolling file appender with Logback-Spring.xml.

Step-by-Step Guide

1. Create a file in /NAME_OF_API_PROJECT/src/main/resources . The name of the file should be logback-spring.xml

2. Edit logback-spring.xml with the following code:

   <?xml version="1.0" encoding="UTF-8"?>
   <configuration scan="true">
   	<appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
   		<encoder>
   			<charset>UTF-8</charset>
   			<Pattern>%d %-4relative [%thread] %-5level %logger{35} - %msg%n</Pattern>
   		</encoder>
   	</appender>
   	<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
   		<file>C:\tmp\srv\logs\application.log</file>
   		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
   			<!-- daily rollover. Make sure the path matches the one in the file element or else
                the rollover logs are placed in the working directory. -->
   			<fileNamePattern>C:\tmp\srv\logs\application_%d{yyyy-MM-dd}.%i.log</fileNamePattern>
   			<!-- size of the log file-->
   			<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
   				<maxFileSize>5MB</maxFileSize>
   			</timeBasedFileNamingAndTriggeringPolicy>
   			<!-- keep 30 days' worth of history -->
   			<maxHistory>30</maxHistory>
   		</rollingPolicy>
   		<encoder>
   			<charset>UTF-8</charset>
   			<pattern>%d %-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
   		</encoder>
   	</appender>
   	<root level="INFO">
   		<appender-ref ref="consoleAppender" />
   		<appender-ref ref="FILE"/>
   	</root>
   	<logger name="org.openlegacy.impl.rpc.support.DefaultRpcSession" level="DEBUG"/>
   </configuration>
