java - 如何在一个文件中记录错误并在另一文件中记录积压的信息

Question

如何根据级别将日志分成两个文件？我发现有人在做一些非常接近的事情，但在一个级别中使用控制台，在另一个级别中使用文件 (logging to different places throw filters) 。另外，我发现了一个非常感兴趣的问题(logging to different places by setup two separate loggers)但是，据我所知，答案是创建两个 Logger 实例，如果我可以按级别过滤，这似乎是不必要的。请参阅以下我迄今为止所做的三件事:

1. 它正在工作，但所有信息都进入同一个文件，
2. 我尝试通过尝试创建两个根标签来根据级别进行分离，但它只是创建了两个空文件
3. 为了缩小我的问题范围，我尝试至少将相同的信息复制到两个不同的文件，但它也只是创建两个空文件

Answer 1

我认为您正在寻找的是新附加程序中的 filter 元素，该元素仅将给定日志级别以上的级别写入新文件。然后您可以在同一个记录器中处理这两个附加程序。

这是一个例子:

<configuration>
    <appender name="RollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>log/app.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/app.%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>14</maxHistory>
        </rollingPolicy>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="ErrorRollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>log/app-warn.log</file>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/app.%d{yyyy-MM-dd}-warn.log</fileNamePattern>
            <maxHistory>14</maxHistory>
        </rollingPolicy>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yy/MM/dd HH:mm:ss.SSS} %-5level %-38logger{38} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="WARN">
        <appender-ref ref="STDOUT"/>
    </root>

    <logger name="com.my.package" level="INFO">
        <appender-ref ref="RollingFile"/>
        <appender-ref ref="ErrorRollingFile"/>
    </logger>
</configuration>
