Java日志系统-logback配置



logback配置文件：logback.xml

<configuration debug="true" scan="true" scanPeriod="5 minutes">
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n%rEx</pattern>
        </encoder>
    </appender>

    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>logs/nexusy-api-%d{yyyy-MM-dd}.%i.gz</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>30</maxHistory>
        </rollingPolicy>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%t] %-5p %c{36} - %m%n</pattern>
            <immediateFlush>false</immediateFlush>
            <outputPatternAsHeader>true</outputPatternAsHeader>
        </encoder>
    </appender>

    <logger name="com.nexusy.demo.api" level="DEBUG" additivity="false">
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="FILE"/>
    </logger>

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

</configuration>

 logback默认现在classpath中查找logback.groovy，找不到再找logback-test.xml,找不到再找logback.xml。Maven等工具打包时会忽略logback-test.xml，因此可以在classpath下同时放logback-test.xml和logback.xml，logback-test.xml用于开发，logback.xml用于生成环境。
