Spring启动多个日志文件

Question

在我的带有"@ Slf4j"注释类的Spring启动项目中,对于某些类,我想要记录到不同的文件.但无法弄清楚如何做到这一点.我有一个logback-spring.xml文件,它从我的属性文件中引用,如下所示:

logging.config= path/to/logback-spring.xml
logging.file=myCurrentLogFile.log

我现在必须创建另一个logback-spring.xml文件吗？或者我可以在当前文件中配置它,如果那样,我该如何选择使用哪个记录器.

Answer 1

只需添加另一个记录器和追加器.例如,我使用以下内容logback.xml

<property name="LOGS_HOME" value="/var/applications/myProject/applogs/" />

<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>

<appender name="FILE"
    class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${LOGS_HOME}myProject_log.log</file>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>
            %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
        </Pattern>
    </encoder>

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- rollover daily -->
        <fileNamePattern>${LOGS_HOME}myProject_log.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>100MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
</appender>

<appender name="FILE-AUDIT" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${LOGS_HOME}myProject_audit.log</file>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>
            %d{yyyy-MM-dd HH:mm:ss};%msg%n
        </Pattern>
    </encoder>

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- rollover daily -->
        <fileNamePattern>${LOGS_HOME}myProject_audit.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>100MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
</appender>

<logger name="com.myCompany.myProject" level="info" additivity="false">
    <appender-ref ref="FILE" />
    <appender-ref ref="STDOUT" />
</logger>

<logger name="audit-log" level="info" additivity="false">
    <appender-ref ref="FILE-AUDIT" />
    <appender-ref ref="STDOUT" />
</logger>

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

在代码中,您可以使用以下命令访问记录器:

private static Logger audit = LoggerFactory.getLogger("audit-log");

这将获得audit-log记录器和使用FILE-AUDITappender.

"standart"appender与指定包中的任何类一起使用:

private static Logger logger = LoggerFactory.getLogger(MyApplication.class);

这将使用<logger name="com.myCompany.myProject" level="info" additivity="false">和显而易见的FILE appender.
