Spring-boot with logback printing some system logs into Application log

Question

I previously has issue,while application printing all logs in console. Then after following some post I was able to print the logs into separate application log.

Now while restarting application server (IBM WAS 8.5) it is printing some SystemOut logs into newly created application log.

Gradle build , Excluded some jars as they were coming from other dependency

            exclude(group: 'org.slf4j', module:'slf4j-nop')
            all*.exclude group: "javax.servlet", module: "servlet-api"
            all*.exclude group: "org.slf4j", module: "log4j-over-slf4j"
            all*.exclude group: "org.slf4j", module: "slf4j-log4j12"
            all*.exclude group: "log4j", module: "log4j"

application.properties :-

        logging.file=MySpringBoot-applicaiton.log

and logback.xml :-

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
        <include resource="org/springframework/boot/logging/logback/defaults.xml" />
        <property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>
        <include resource="org/springframework/boot/logging/logback/file-appender.xml" />

        <root level="INFO">
            <appender-ref ref="FILE" />
        </root>
    </configuration>

MySpringBoot-applicaiton.log:

Here in the last two line of logs, it is a message from server ,which is printing into application log now.

=================================================================== UPDATE:

2018-11-06 15:40:24.291  WARN 27132 --- [P=756984:O=0:CT] com.ibm.ws.runtime.WsServerImpl          : WSVR0001I: Server server1 open for e-business

The above line is now printing into applicaiton log while using logback with springboot. No logback xml configuration just added the logging.file= into applicaiton.properties file.

The above log is a IBM WebSphere log. how that is coming to my applicaiton log.

I ran into similar problem. You can redirect the server startup related information from the application log to the websphere stdout.log by adding the following in the logback.xml :-

<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>

<logger name="com.ibm.ws.runtime" level="warn"
    additivity="false">
    <appender-ref ref="STDOUT" />
</logger>

<root level="WARN">
    <appender-ref ref="STDOUT" />
</root>
