Log file is created automatically by springboot

Question

I wanted to use 2 log file for my springboot project.So, I created a logback.xml which is suitable for that purpose.

<?xml version = "1.0" encoding = "UTF-8"?> <configuration>

<timestamp key="timestamp" datePattern="ddMMyyyy"/>

    <appender name="STDOUT"
            class="ch.qos.logback.core.ConsoleAppender">
            <layout class="ch.qos.logback.classic.PatternLayout">
                    <Pattern>
                            %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
                    </Pattern>
            </layout>
    </appender>

    <appender name="FILE"
            class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>logs/student${timestamp}.log</file>
            <encoder
                    class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                    <Pattern>
                            %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
                    </Pattern>
            </encoder>

            <rollingPolicy
                    class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                    <!-- rollover daily -->
                    <fileNamePattern>logs/student_.%d{ddMMyyyy}.log
                    </fileNamePattern>
            </rollingPolicy>
    </appender>

    <appender name="FILE-AUDIT"
            class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>logs/teacher${timestamp}.log</file>
            <encoder
                    class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                    <Pattern>
                            %d{yyyy-MM-dd HH:mm:ss};%msg%n
                    </Pattern>
            </encoder>

            <rollingPolicy
                    class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                    <!-- rollover daily -->
                    <fileNamePattern>logs/teacher_.%d{ddMMyyyy}.log
                    </fileNamePattern>
            </rollingPolicy>
    </appender>

    <logger name="com.training.application" level="info"
            additivity="false">
            <appender-ref ref="FILE" />
            <appender-ref ref="STDOUT" />
    </logger>

    <logger name="audit-log" level="info" additivity="false">
            <appender-ref ref="FILE-AUDIT" />
            <appender-ref ref="STDOUT" />
    </logger>

    <root level="error">
            <appender-ref ref="FILE" />
            <appender-ref ref="STDOUT" />
    </root>

My logger variables are like that :

private static Logger LOG = LoggerFactory.getLogger(TrainingBatch.class);//studentlog

private static Logger audit = LoggerFactory.getLogger("audit-log");//teacher log

My spring-boot applicatons runs with one argument.First one is bootstrap.sh start student or ./bootstrap.sh start teacher

My problem is when I give the command bootstrap.sh start student application log info is written student_... log file and also LOG.info etc.That is okey.It is correct.But another log file (student_...) is also created automatically.Or vica -versa.

How do we stop this situation?I want that If I give student command in command line,I want student log file should be created or If I give teachercommand in command line, teacher log file should be created.Server log info is not important for me.I wish they should not been written to any log file.

My bootstrap.sh =>

#!/bin/bash

Instead of using two file appenders use one file appender with a variable role. example

<appender name="FILE"
            class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>logs/{sys:role}${timestamp}.log</file>
            <encoder
                    class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                    <Pattern>
                            %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
                    </Pattern>
            </encoder>
            <rollingPolicy
                    class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                    <!-- rollover daily -->
                    <fileNamePattern>logs/{sys:role}_.%d{ddMMyyyy}.log
                    </fileNamePattern>
            </rollingPolicy>
    </appender>

change bootstrap.sh line

 nohup $JAVA_PATH -jar $JAVA_OPT $JARFILE $SECRET_KEY &

to

 nohup $JAVA_PATH -Drole="$2" -jar $JAVA_OPT $JARFILE $SECRET_KEY &
