logback日志框架简单使用

依赖 

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

配置：logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">

    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
    <property name="LOG_HOME" value="./logs/" />

    <!--控制台日志 -->
    <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="defaultAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${LOG_HOME}/test.log</File>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${LOG_HOME}/test.%d{yyyy-MM-dd}.%i.log.zip</FileNamePattern>
            <MaxHistory>30</MaxHistory>
            <cleanHistoryOnStart>false</cleanHistoryOnStart>
            <TimeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <MaxFileSize>1GB</MaxFileSize>
            </TimeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
    </appender>

    <!-- 日志输出级别 -->
    <root level="INFO">
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="defaultAppender"/>
    </root>

</configuration>
           

代码中使用：

private static final Logger LOGGER = LoggerFactory.getLogger(xxx.class);
