【spring-boot】logback+slf4j 日志组合

现在主流的都使用logback+slf4j进行日志打印。

slf4j 需要配置maven

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>

logback-spring.xml

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %d{HH:mm:ss.SSS} %-5level %logger{80} - %msg%n
            </pattern>
        </layout>

    </appender>

    <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>

            <onMismatch>ACCEPT</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %msg%n
            </pattern>
        </encoder>
        <!--        滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--            文件路径-->
            <fileNamePattern>
                /mfw_data/imooc_log/study/springboot/info.%d.log
            </fileNamePattern>

        </rollingPolicy>
    </appender>


    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--        根据范围过滤-->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>

        <encoder>
            <pattern>
                %msg%n
            </pattern>

        <!--        滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--            文件路径-->
            <fileNamePattern>
                /mfw_data/imooc_log/study/springboot/error.%d.log
            </fileNamePattern>

        </rollingPolicy>
    </appender>

    <root level="info">
        <appender-ref ref="consoleLog"></appender-ref>
        <appender-ref ref="fileInfoLog"></appender-ref>
        <appender-ref ref="fileErrorLog"></appender-ref>
    </root>
</configuration>
