java - 使用 Spring Boot 配置 Logback

Question

我在 Spring Boot 应用程序中使用 Logback 进行日志管理，我如何需要这些规范:

• 将所有内容记录到文件中
• 将重要内容记录到控制台
• 使用滚动策略，最大文件大小为 10MB

Answer 1

我使用了这个 logback.xml 配置文件，它运行得很好:

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

    <property name="DEV_HOME" value="logging"/>
    <appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <charset>UTF-8</charset>
            <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>
        </encoder>
    </appender>

    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${DEV_HOME}/debug.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- daily rollover. Make sure the path matches the one in the file element or else
             the rollover logs are placed in the working directory. -->
            <fileNamePattern>${DEV_HOME}/archived/debug.%d{yyyy-MM-dd}.%i.log</fileNamePattern>

            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>5MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <!-- keep 30 days' worth of history -->
            <maxHistory>30</maxHistory>
        </rollingPolicy>

        <encoder>
            <charset>UTF-8</charset>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="DEBUG">
        <appender-ref ref="FILE"/>
    </root>
    <root level="INFO">
        <appender-ref ref="consoleAppender" />
    </root>
</configuration>
