Java : logback简单配置

需要把logback.xml文件放在类路径下,如果是spring boot项目可以用 logging.config=classpath:log/xxxxxx.xml来指定配置文件

logback layout可以参考: https://logback.qos.ch/manual/layouts.html

以下是配置文件示例:

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="false" scanPeriod="120 seconds" debug="false">
    <contextName>myLog</contextName>
    <property name="LOG_ROOT" value="C:\Users\cy\Desktop\ssm1\duo" />

    <!-- 控制台STDOUT -->
    <appender name="STDOUT-APPENDER" class="ch.qos.logback.core.ConsoleAppender">
        <param name="target" value="System.out"/>
        <encoder charset="UTF-8">
            <pattern>%d [%t] %-5p %c - [%msg]%n</pattern>
        </encoder>
    </appender>

    <!-- 控制台STDERR -->
    <appender name="STDERR-APPENDER" class="ch.qos.logback.core.ConsoleAppender">
        <param name="target" value="System.err"/>
        <encoder charset="UTF-8">
            <pattern>%d [%t] %-5p %c - [%msg]%n</pattern>
        </encoder>
    </appender>

    <!--默认记录-->
    <appender name="DEFAULT-APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_ROOT}/log/default.log</file>
        <append>true</append>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_ROOT}/log/backup/default.%d{yyyyMMdd}.log</fileNamePattern>
            <maxHistory>3</maxHistory>
        </rollingPolicy>
        <encoder charset="UTF-8">
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5p %c - [%msg]%n</pattern>
        </encoder>
    </appender>

    <!--分类文件记录,如果日志太多默认记录不满足需求,可以分类存储-->
    <appender name="ES-APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_ROOT}/log/es.log</file>
        <append>true</append>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_ROOT}/log/backup/es.%d{yyyyMMdd}.log</fileNamePattern>
            <maxHistory>3</maxHistory>
        </rollingPolicy>
        <encoder charset="UTF-8">
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5p %c - [%msg]%n</pattern>
        </encoder>
    </appender>

    <!--文件异常记录-->
    <appender name="ERROR-APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_ROOT}/log/error.log</file>
        <append>true</append>
        <!--过滤掉ERROR级别以下的日志信息-->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_ROOT}/log/backup/error.%d{yyyyMMdd}.log</fileNamePattern>
            <maxHistory>3</maxHistory>
        </rollingPolicy>
        <encoder charset="UTF-8">
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5p %C - [%msg]%n</pattern>
        </encoder>
    </appender>

    <!--控制台标准输出-->
    <logger name="STDOUT" level="INFO" additivity="false">
        <appender-ref ref="STDOUT-APPENDER"/>
    </logger>
    <!--控制台错误输出-->
    <logger name="STDERR" level="ERROR" additivity="false">
        <appender-ref ref="STDERR-APPENDER"/>
    </logger>
    <!--分类INFO输出,到文件-->
    <logger name="ES" level="INFO" additivity="false">
        <appender-ref ref="ES-APPENDER"/>
    </logger>
    <!--所有ERROR输出-->
    <logger name="ERROR" level="ERROR" additivity="false">
        <appender-ref ref="ERROR-APPENDER"/>
    </logger>

    <root level="INFO">
        <!--默认记录输出到DEFAULT-APPENDER-->
        <appender-ref ref="DEFAULT-APPENDER"/>
