Java 回写：消除isn'；t在后台工作

我正在做一个项目，我使用slf4j和logback进行日志记录。问题是日志的级别是动态的，由用户选择。因此，用户也可以停止日志记录，这样他就可以获得空间（我们记录了很多东西，如果流量很大，很快就会非常昂贵）

为此，我将一些变量保存在属性文件中，每次更改时都重新加载它。但我并没有像上面所说的那个样，成功地使它和leveloff（用于禁用日志）一起工作

这是我的logback.xml：

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

<configuration scan="false"> 
<!-- We don't need the logback.xml to be checked every time, we will trigger in java
the reload if we need it -->

    <property file="/opt/program/log.properties"/>

    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>

    <!-- To enable JMX Management -->
    <jmxConfigurator/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${PATTERN_LOGS}</pattern>
        </encoder>
    </appender>

     <appender name="generalFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
         <file>${LOG_GENERAL_PATH}.log</file>
         <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
            <fileNamePattern>${LOG_GENERAL_FILENAME}.%d{yyyy-MM-dd}.log</fileNamePattern>
            <MaxHistory>30</MaxHistory>
          </rollingPolicy>
        <encoder>
            <pattern>${PATTERN_LOGS}</pattern>
        </encoder>
      </appender>

      <appender name="httpFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
         <file>${LOG_HTTP_PATH}.log</file>
         <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
            <fileNamePattern>${LOG_HTTP_FILENAME}.%d{yyyy-MM-dd}.log</fileNamePattern>
            <MaxHistory>30</MaxHistory>
          </rollingPolicy>
        <encoder>
            <pattern>${PATTERN_LOGS}</pattern>
        </encoder>
      </appender>

       <appender name="errorFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
         <file>${LOG_ERROR_PATH}.log</file>
         <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
            <fileNamePattern>${LOG_ERROR_FILENAME}.%d{yyyy-MM-dd}.log</fileNamePattern>
            <MaxHistory>30</MaxHistory>
          </rollingPolicy>
        <encoder>
            <pattern>${PATTERN_LOGS}</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
      </appender>

     <logger name="http" level="DEBUG" additivity="false">
        <appender-ref ref="httpFile"/>
        <appender-ref ref="generalFile"/>
        <appender-ref ref="console"/>
    </logger>

    <root level="${LEVEL_ROOT}">
        <appender-ref ref="console"/>
        <appender-ref ref="generalFile"/>
        <appender-ref ref="errorFile"/>
    </root>
</configuration>

根据您提供的logback状态消息，根记录器将按预期设置为水平。然而，名为“http”的记录器被设置为DEBUG，我怀疑这是问题的根源

---

在任何情况下，从不同的记录器引用相同的appender都是一个坏主意。此外，配置文件会执行两次，附加程序名为“generalFile”和“errorFile”同样，从不同的记录器引用同一个appender是一个坏主意，不受支持。

状态消息会说什么？请看详细情况。在我的问题上能得到你的帮助是我的荣幸。我已经在我的问题中添加了日志。谢谢，它正在工作。现在我遇到了一个问题，因为当我从记录器http中删除appender

generalFIle

和

console

时，我在“generalFIle”和“console”中丢失了

http

日志。在名为http的记录器中，将additivity设置为true，或者只是删除additivity属性，它将默认为true。
