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。

添加另一个记录器和追加器。
例如,我使用了以下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
记录器并使用FILE-AUDIT
appender。
“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obviosly FILE appender。

如果要具有两个不同的文件,则需要在标签<appender>
下添加以下代码:
<File name="FILE-AUDIT-SUIVI" fileName="${LOGS_HOME}myProject_audit.log">
<PatternLayout>
<pattern>
${LOGS_HOME}
</pattern>
</PatternLayout>
</File>
<RollingFile name="FileAppender" fileName="${LOGS_HOME}archived/myProject_audit.log"
filePattern="${LOGS_HOME}archived/myProject_audit.%d{yyyy-MM-dd}.%i.log">
<PatternLayout>
<Pattern>${LOGS_HOME}</Pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy size="10MB" />
</Policies>
<DefaultRolloverStrategy max="1" />
</RollingFile>
