本文详细介绍了如何在项目中引入logback依赖，配置logback.xml以实现不同级别的日志输出，包括控制台和文件输出，并展示了如何在Spring Boot中指定logback配置。

1、logback需要引入的依赖

 　　　　 <!--logback-->
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.2.1</version>
        </dependency>
        <!--logback spring扩展-->
        <dependency>
            <groupId>org.logback-extensions</groupId>
            <artifactId>logback-ext-spring</artifactId>
            <version>0.1.4</version>
        </dependency>

2、logback.xml的配置

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <jmxConfigurator/>
    <!-- 控制台输出日志 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
        </layout>
    </appender>
    <appender name="ERROR-OUT" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>my-logs/error.log</file>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily -->
            <fileNamePattern>my-logs/error-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy
                    class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!-- or whenever the file size reaches 100MB -->
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
    </appender>
    <appender name="INFO-OUT" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>my-logs/info.log</file>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -

        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
