你能为同一个包提供两个级别吗

Question

我们可以在appender级别设置ERROR和INFO级别吗？

我使用logback.xml

我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> 

我可以知道附加器将执行写入部件（输出）.logger将其重定向到正确的appender与它的属性。

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。

我的目标是在一个文件中写入ERROR数据，在另一个文件中写入INFO数据。

你需要的是levelfilter在附加器，配置级过滤错误日志

<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> 

我假设你正在寻找只记录以下

 <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> 

而对于信息显示错误出的appender信息和错误记录在两个单独的文件中，否则您可能需要扩展过滤器。
