Question

我们能否在appender级别设置ERROR和INFO级别？。

我正在使用logback.xml

我的logback.xml

    <configuration>
        <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>%5p [%t] %m%n</pattern>
            </encoder>
            <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
                <level>DEBUG</level>
            </filter>
        </appender>
        <appender name="default-out" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- Rolling file appender for rolling files -->
            <param name="File" value="logs/app-track-log.log" />
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- daily rollover -->
                <fileNamePattern>logs/app-track-log-%d{yyyy-MM-dd}.log</fileNamePattern>

                <!-- keep 30 days' worth of history -->
                <maxHistory>30</maxHistory>
            </rollingPolicy>
            <param name="encoding" value="UTF-8" />
            <encoder>
                <pattern>%-30([web] %d{HH:mm:ss.SSS} [%thread]) %-5level %logger{32} - %msg%n</pattern>
            </encoder>
        </appender>

        <appender name="error-out" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- Rolling file appender for rolling files -->
            <param name="File" value="logs/error/app-error.log" />
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- daily rollover -->
                <fileNamePattern>app-error.%d{yyyy-MM-dd}.log</fileNamePattern>
                <!-- keep 30 days' worth of history -->
                <maxHistory>30</maxHistory>
            </rollingPolicy>
            <param name="encoding" value="UTF-8" />
            <encoder>
                <pattern>%-30([web] %d{HH:mm:ss.SSS} [%thread]) %-5level %logger{32} - %msg%n</pattern>
            </encoder>
        </appender>
<!--here the logger to initiate the write operation -->
        <logger name="org.company.controllers" level="ERROR" >
            <appender-ref ref="error-out" /> 
        </logger>

    <logger name="org.company.controllers" level="INFO" >
    <appender-ref ref="default-out" /> 
    </logger>

        <root level="OFF">
            <appender-ref ref="default-out"  />
        </root>
    </configuration>

我知道appender将执行写入部分（输出）.logger会将其重定向到右侧的appender及其属性。

在我的情况下，我需要在不同的记录器级别（INFO / ERROR）中使用相同的包来提供不同文件中的数据。

我的目标是将ERROR数据写入一个文件，将INFO数据写入另一个文件。

你需要的是appender中的levelfilter，为下面显示的错误输出appender配置级别过滤器ERROR

       <appender name="error-out" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- Rolling file appender for rolling files -->
            <param name="File" value="logs/error/app-error.log" />
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- daily rollover -->
                <fileNamePattern>app-error.%d{yyyy-MM-dd}.log</fileNamePattern>
                <!-- keep 30 days' worth of history -->
                <maxHistory>30</maxHistory>
            </rollingPolicy>
            <param name="encoding" value="UTF-8" />
            <filter class="ch.qos.logback.classic.filter.LevelFilter">
                <level>ERROR</level>
                <onMatch>ACCEPT</onMatch>
                <onMismatch>DENY</onMismatch>
            </filter>
            <encoder>
                <pattern>%-30([web] %d{HH:mm:ss.SSS} [%thread]) %-5level %logger{32} - %msg%n</pattern>
            </encoder>
        </appender>

用于信息记录

<appender name="default-out" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- Rolling file appender for rolling files -->
            <param name="File" value="logs/app-track-log.log" />
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <!-- daily rollover -->
                <fileNamePattern>logs/app-track-log-%d{yyyy-MM-dd}.log</fileNamePattern>

                <!-- keep 30 days' worth of history -->
                <maxHistory>30</maxHistory>
            </rollingPolicy>
            <param name="encoding" value="UTF-8" />
            <filter class="ch.qos.logback.classic.filter.LevelFilter">
                <level>INFO</level>
                <onMatch>ACCEPT</onMatch>
                <onMismatch>DENY</onMismatch>
            </filter>
            <encoder>
                <pattern>%-30([web] %d{HH:mm:ss.SSS} [%thread]) %-5level %logger{32} - %msg%n</pattern>
            </encoder>
        </appender>

我假设您正在寻找仅在两个单独的文件中记录信息和错误日志，否则您可能需要扩展过滤器。

你能为同一个包提供两个级别吗？
