Logback 缺少 RollingFileAppender 和 AysncAppender 的条目

Logback missing entries for RollingFileAppender and AysncAppender

您好,我使用的是 logback 版本 1.1.10,我的配置如下: 我在记录事件时遇到了一个大问题,找不到所需的日志。

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

<configuration>

  <appender name="abc_req" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>${log}/abc/request/request.log</File>

    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>${log}/abc/request/request.log.%d{yyyy-MM-dd-HH}</fileNamePattern>
    </rollingPolicy>
  </appender>

  <appender name="abc1_res" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>${log}/abc1/response/response.log</File>
    <encoder>
      <pattern>%m%n</pattern>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>${log}/abc1/response/response.log.%d{yyyy-MM-dd-HH}</fileNamePattern>
    </rollingPolicy>
  </appender>

  <appender name="abc2_error" class="ch.qos.logback.core.rolling.RollingFileAppender">

    </rollingPolicy>
  </appender>

  <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">

  </appender>


  <logger name="abcLogRequest" level="INFO" additivity="false">

    </appender>

    <appender name="responseQueue" class="ch.qos.logback.classic.AsyncAppender">
        <discardingThreshold>0</discardingThreshold>
        <queueSize>1000</queueSize>
        <appender-ref ref="abc1_res"/>
    </appender>

    <appender name="errorQueue" class="ch.qos.logback.classic.AsyncAppender">
        <discardingThreshold>0</discardingThreshold>
        <queueSize>500</queueSize>
        <appender-ref ref="abc2_error"/>
    </appender>
  <!-- 
  <shutdownHook class="ch.qos.logback.core.hook.DelayingShutdownHook"/> -->

  <root level="INFO">
    <appender-ref ref="stdout"/>
  </root>
</configuration>

但是在签入滚动文件时,文件中丢失了很多日志条目。

在上述情况下确实需要帮助。

任何help/suggestion真的可以帮到我很多!

终于解决了!

问题:有 2 个 JVM 试图写入一个公共文件。

所以只需在 RollingFileAppender 中添加以下内容

<prudent>true</prudent>

并在配置中删除文件参数。

<appender name="abc_req" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <prudent>true</prudent>
    <encoder>
      <pattern>%m%n</pattern>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>${log}/abc/request/request.log.%d{yyyy-MM-dd-HH}</fileNamePattern>
    </rollingPolicy>
  </appender>

另外,通过 rollingPolicy 中的 fileNamePattern,我能够提供正确的文件路径。
