logback-spring.xml does not work when deploy on tomcat

I hava create spring boot project with Java 8, and I am using external Tomcat container to deploy. I hava a logbakc-spring.xml as follows:

<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>INFO</level>
    </filter>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${LOG_PATH}/log/hfxn.%d{yyyy-MM-dd}.log</fileNamePattern>
    <maxHistory>90</maxHistory>
    </rollingPolicy>
    <encoder>
        <charset>utf-8</charset>
        <Pattern>%d %-5level [%thread] %logger{0}: %msg%n</Pattern>
    </encoder>
</appender>

But, when I build into war, and deploy on Tomcat, I cannot find the log file in the path where I specified, and , I don't know why?

A logback file named logback-spring.xml works well if your project is spring-boot compatible, but when you deploy your project as war into tomcat, this file is not picked because of naming a constraint on logback file.

A logback file can have only 1 of these 3 allowed names:

  • logback-test.xml
  • logback.groovy
  • logback.xml

As soon as you change the name of the file as one of the above, logback config will start working with war package deployed over Tomcat.

Do you see the logback file found in the console messages? Try naming the file logback.xml, which is a standard logback name that it searches for at startup. Also, ensure the file is at the top level in the jar, not nested in a subdirectory.
