本文详细介绍如何使用Logback进行日志配置，包括Maven依赖引入、简单与复杂配置示例，以及通过SLF4J进行日志记录的测试代码。深入解析不同级别的日志输出策略，如错误、警告、信息等，并演示了如何将日志输出到控制台和不同的日志文件。

一、pom.xml

<!-- 实现slf4j接口并整合 -->
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.2</version>
</dependency>

二、logback.xml

1.简单配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="debug">
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>

2.详细配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <!-- 控制台 appender -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <!-- 出错日志 appender  -->
    <appender name="ERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- 按天回滚 daily -->
            <!-- log.dir 在maven profile里配置 -->
            <fileNamePattern>./log/error/daotong-error-%d{yyyy-MM-dd}.log</fileNamePattern>
            <!-- 日志最大的历史 60天 -->
            <maxHistory>60</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
        <!-- 只打印错误日志 -->
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <!-- 访问日志 appender  -->
    <appender name="WARN" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- 按天回滚 daily -->
            <fileNamePattern>./log/warn/daotong-warn-%d{yyyy-MM-dd}.log</fileNamePattern>
            <!-- 日志最大的历史 60天 -->
            <maxHistory>60</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
        <!-- 只打印WARN日志 -->
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>WARN</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <!-- info日志 appender  -->
    <appender name="INFO" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- 按天回滚 daily -->
            <fileNamePattern>./log/info/daotong-info-%d{yyyy-MM-dd}.log</fileNamePattern>
            <!-- 日志最大的历史 60天 -->
            <maxHistory>60</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
        <!-- 只打印错误日志 -->
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <!--日志打印的包的范围，及分类日志文件存储 -->
    <logger name="com.daotonginfo.manage" additivity="false">
        <level value="INFO" />
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="ERROR"/>
        <appender-ref ref="WARN"/>
        <appender-ref ref="INFO" />
    </logger>
    <!--控制台打印资源加载信息-->
    <root level="info">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

三、测试

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Te {

    private static final Logger logger = LoggerFactory.getLogger(Te.class);

    public static void main(String[] args) {

        logger.info("haha");

    }
