如何配置logback以自动gzip我的日志？

Question

我在我的java web appliaction中使用logback.这是我的"logback.xml"文件.

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

    <property name="LOG_DIR" value="/home/ying/.jetty_logs/vehicle" />

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%date [%thread] %-5level %logger{36}[%L] - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="LAST" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_DIR}/last.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>last.%d{yyyy-MM}.gz</fileNamePattern>
            <maxHistory>24</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%date:%msg%n</pattern>
        </encoder>
    </appender>

    <logger name="org.springframework" level="WARN" />
    <logger name="org.apache.shiro" level="WARN" />
    <logger name="org.hibernate" level="WARN" />

    <logger name="ying.car.interceptor.AutoLoginInterceptor" additivity="false" level="INFO">
        <appender-ref ref="LAST" />
    </logger>
    <logger name="ying.car.controller.LoginController" additivity="false" level="INFO">
        <appender-ref ref="LAST" />
    </logger>
    <logger name="ying.car.controller.LogoutController" additivity="false" level="INFO">
        <appender-ref ref="LAST" />
    </logger>

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

</configuration>

今天是2013年6月1日,所有我的旧日志都被覆盖,没有创建*.gz.请有人帮助我.

Answer 1

试着这样做,希望它能为你效劳.

<appender name="FILE"
    class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>${LOGDIR}/filename.log</File>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- rollover daily -->
        <FileNamePattern>${LOGDIR}/file.%d{yyyy-MM-dd}.%i.log.gz
        </FileNamePattern>
        <!-- keep 30 days' worth of history -->
        <MaxHistory>30</MaxHistory>
        <!-- or whenever the file size reaches 10MB -->
        <timeBasedFileNamingAndTriggeringPolicy
            class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>%date [%thread] %-5level %logger{36} - %msg%n
        </Pattern>
    </encoder>
</appender>

上面的代码将在当天压缩您的文件或如果日志文件大小超过10MB.

注意:我在filePattern中添加了"%i",它会将文件名重复为file1,file2等.

尝试添加<cleanHistoryOnStart>true</cleanHistoryOnStart>以便在下次启动时发生翻转,就好像它在翻滚时没有运行一样,它不会发生.
