Empty log file created for every profile which is configured in spring logback

Question

I am using the below logback-spring.xml file in my spring boot application. Profile-specific Configuration is enabled in the xml file. But when my environment is test it is writing the the entries in example-wsrest_test.log file , but then also it is creating the other two log files example-wsrest_prod.log and example-wsrest_acc.log when server starts. Is it possible to create only single log file based on the profile.

You have to define appender inside spring profile tag. All appenders inside configuration tag are initialized but log is written to files based on spring profiles only. But to have a single log file per profile, each profile should have its own appender. Example below might help :

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

    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>

    <springProfile name="test">
        <appender name="FILE_APPENDER_TEST" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <encoder>
                <pattern>${FILE_LOG_PATTERN}</pattern>
                <charset>utf8</charset>
            </encoder>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>%d{yyyy-MM-dd}-test.log</fileNamePattern>
                <maxHistory>30</maxHistory>
            </rollingPolicy>
        </appender>
        <root level="TRACE">
            <appender-ref ref="FILE_APPENDER_TEST"/>
        </root>
    </springProfile>

    <springProfile name="prod">
        <appender name="FILE_APPENDER_PROD" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>%d{yyyy-MM-dd}-prod.log</fileNamePattern>
                <maxHistory>30</maxHistory>
            </rollingPolicy>
            <encoder>
                <pattern>${FILE_LOG_PATTERN}</pattern>
                <charset>utf8</charset>
            </encoder>
        </appender>
        <root level="INFO">
            <appender-ref ref="FILE_APPENDER_PROD"/>
        </root>
    </springProfile>

</configuration>
