logback配置

1.maven配置pom.xml：

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jcl-over-slf4j</artifactId>
            <version>${slf4j.version}</version>
            <type>jar</type>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>${logback.version}</version>
        </dependenc

2.在resource目录添加logback.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
    </appender>
    <appender name="info" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${catalina.base}/logs/systemInfo.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${catalina.base}/logs/systemInfo-%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>15</maxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%-5p [%d][%mdc{mdc_userId}] %C:%L - %m %n</pattern>
            <charset>utf-8</charset>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>INFO</level>
        </filter>
    </appender>
    
    <root level="INFO">
        <appender-ref ref="info" />
    </root>
</configuration>
