/tmp/spring.log file is generating on spring boot service startup e

[manjunadh]

Hi,
I am using spring boot 1.59 version.

I have logback-spring.xml with proper configurations still spring boot application is generating /tmp/spring.log file on application start up.

Below are my logback-spring.xml configurations.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
	<include resource="org/springframework/boot/logging/logback/base.xml"/>
	<jmxConfigurator/>
	
	<property name="CONSOLE_LOG_PATTERN"
        value="%d{MM/dd/yyyy HH:mm:ss.SSS XXX} ${LOG_LEVEL_PATTERN:-%5p} ${PID:- } -- [%thread] %logger{60} : %msg%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/>

	<!-- Appender to log to file -->
	<springProfile name="local,bamboo">​
	<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
		<file>logs/service.log</file>
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
		  <!-- daily rollover -->
		  <fileNamePattern>logs/service.%d{yyyy-MM-dd}_%i.gz</fileNamePattern>
		  <timeBasedFileNamingAndTriggeringPolicy
			  class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
			  <!-- or whenever the file size reaches 10MB -->
			<maxFileSize>10MB</maxFileSize>
		  </timeBasedFileNamingAndTriggeringPolicy>
		  <!-- keep 7 days' worth of history -->
		  <maxHistory>7</maxHistory>
		</rollingPolicy>
		<encoder>
			<pattern>${CONSOLE_LOG_PATTERN}</pattern>
			<charset>utf8</charset>
		</encoder>
	</appender>
	<root >
		<appender-ref ref="file" level="INFO" />
	</root>
​	</springProfile>

</configuration>

Please suggest some fix

[wilkinsona]

It's difficult to suggest a fix when we can't see everything. Can you please provide a minimal, complete, and verifiable example of the behaviour that you have described?

[manjunadh]

you can replicate with below project

[wilkinsona]

Thanks for the sample. Your logback-spring.xml is including org/springframework/boot/logging/logback/base.xml. That, in turn, includes Boot's default file appender configuration which writes to /tmp/spring.log by default.

[manjunadh]

please suggest the replacement for org/springframework/boot/logging/logback/base.xml in logback-spring.xml

[wilkinsona]

The replacement should be whatever is appropriate for how you want your logging to be configured and that doesn't include a file appender that logs to /tmp/spring.log by default. Only you can know what that is and only you know what your requirements are.
