如何在 logback-spring.xml 中包含自定义 xml？

Question

我已经创建了一个公共日志备份-common.xml。我想在另一个文件中使用此文件 - logback.spring.xml。请帮助我如何有效地使用它。

截至目前，应用程序正在启动，但控制台中未打印日志，也未将日志填充到日志文件中。请帮忙。不要将其标记为重复，因为我已经尝试了几乎所有的方法并且我已经为此投入了 2 天时间。与此相关的其他问题没有附加有效答案。

您需要使用下面的“资源”而不是“文件”来为您的子配置（因为它存在于类路径中）

<include resource="logback-common.xml"/>

当 logback 能够找到并加载所有配置文件时，您会看到控制台上打印的信息，因为 logback 在初始阶段被引导。

更新：- 关于您分享的错误 - 您还需要在子配置文件中使用 included 标签而不是 configuration 标签。测试了以下配置，它对我来说工作正常。

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <property resource ="application.yml"/>
    <springProperty name="NAME" source="spring.application.name" />
    <include resource="logback-common.xml"/>
</configuration>

子配置为

logback-common.xml

<?xml version="1.0" encoding="UTF-8"?>
<included>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
    <property name="LOGS" value="./logs" />
    <appender name="Console"
        class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%C{1.}): %msg%n%throwable
            </Pattern>
        </layout>
    </appender>

    <appender name="RollingFile"
        class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOGS}/${NAME}.log</file>
        <encoder
            class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
        </encoder>

        <rollingPolicy
            class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily and when the file reaches 10 MegaBytes -->
            <fileNamePattern>${LOGS}/archived/spring-boot-logger-%d{yyyy-MM-dd}.%i.log
            </fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy
                class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
    </appender>
    
    <!-- LOG everything at INFO level -->
    <root level="info">
        <appender-ref ref="RollingFile" />
        <appender-ref ref="Console" />
    </root>

    
    <logger name="com.ms" level="trace" additivity="false">
        <appender-ref ref="RollingFile" />
        <appender-ref ref="Console" />
