java日志管理

一. logback日志

1.pom.xml导入包

<!-- 1.日志 -->
        <!-- 实现slf4j接口并整合 -->
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.2.1</version>
        </dependency>

2.日志的配置文件配置：logback.xml 配置方式多种可以百度

 

 

<?xml version="1.0" encoding="UTF-8" ?>
<!--
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。
-->

<configuration scan="true" scanPeriod="60 seconds" debug="false">
