SpringBoot学习- 9、Slf4j日志

SpringBoot学习足迹

在上一篇学习中

 通过画红线的注解，可以直接在下面log.debug输出日志到控制台，但是写日志文件就没那么顺利了，一直不成功，找了N种配置，以下配置方法可行

首先确保已引入lombok及插件

1、在Resource目录下配置文件logback-spring.xml内容如下

<?xml version="1.0" encoding="UTF-8"?>
<configuration  scan="true" scanPeriod="10 seconds">

    <contextName>logbackcontextName>


    
    <property name="LOG_PATTERN" value="%date{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n" />

    
    <property name="FILE_PATH" value="D:/log/spring-log.%d{yyyy-MM-dd}.%i.log" />

    
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>INFOlevel>
        filter>
        <encoder>
            
            <pattern>${LOG_PATTERN}pattern>
        encoder>
    appender>

    
    <appender name="rollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">

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

            <fileNamePattern>${FILE_PATH}fileNamePattern>

            
            <maxHistory>30maxHistory>

            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                
                <maxFileSize>2MBmaxFileSize>
            timeBasedFileNamingAndTriggeringPolicy>

            
            <totalSizeCap>1GBtotalSizeCap>
        rollingPolicy>

        <encoder>
            <pattern>${LOG_PATTERN}pattern>
        encoder>
    appender>

    
    <logger name="net.sh.rgface.serive" level="ERROR" />

    
    <root level="INFO">
        <appender-ref ref="console" />
        <appender-ref ref="rollingFile" />
    root>
configuration>

 2、输出文件，证明写文件成功
