springboot集成logback

1、引入maven依赖

        <!--logback日志-->
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.2.3</version>
        </dependency>

2、再resource下面新建一个文件名称为 logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="10 seconds">
 
    
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
 
    <!-- 日志级别从低到高分为TRACE < DEBUG < INFO < WARN < ERROR < FATAL，如果设置为WARN，则低于WARN的信息都不会输出 -->
    <!-- scan:当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true -->
    <!-- scanPeriod:设置监测配置文件是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。 -->
    <!-- debug:当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。 -->
 
    <springProperty scope="context" name="module_name" source="spring.application.name"/>
 
    <!-- 时间滚动输出 level为 INFO 日志 -->
    <appender name="RollingFileInfo" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!-- 此日志文件只记录info级别的 -->
        <file>../logs/${module_name}-info.log</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ssS} %5p [%c]:%L-%m%n</pattern>
            <charset class="java.nio.charset.Charset">UTF-8</charset>
        </encoder>
        <prudent>false</prudent>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>../logs/${module_name}-%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>15</maxHistory>
        </rollingPolicy>
    </appender>
 
 
    <appender name="RollingFileERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>../logs/${module_name}-error.log</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ssS} %5p [%c]:%L-%m%n</pattern>
            <charset class="java.nio.charset.Charset">UTF-8</charset>
        </encoder>
        <prudent>false</prudent>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>../logs/${module_name}.%d{yyyy-MM-dd}.log.gz</fileNamePattern>
            <maxHistory>7</maxHistory>
        </rollingPolicy>
    </appender>
 
 
    <!--additivity:是否继承root节点，默认是true继承。默认情况下子Logger会继承父Logger的appender，
    也就是说子Logger会在父Logger的appender里输出。
    若是additivity设为false，则子Logger只会在自己的appender里输出，而不会在父Logger的appender里输出。-->
<!--    <logger name="com.lx" level="INFO" additivity="false">-->
<!--        <appender-ref ref="RollingFileInfo"/>-->
<!--    </logger>-->
<!--    指定包下 日志输出级别-->
    <logger name="com.lx" level="info" />
    <!-- 从低到高为：All < Trace < Debug < Info < Warn < Error < Fatal < OFF-->
    <root level="warn">
        <appender-ref ref="RollingFileERROR"/>
    </root>
</configuration>
