本文主要讲述logback的详细配置

首先在pom.xml中引入loback依赖的jar包，代码如下所示：

<dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.0.13</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <version>1.0.13</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.7</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.7</version>
    </dependency>

一份自动回滚日志的配置文件，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
        
        <property name="LOG_HOME" value="D://logs"/>
    
    
        
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            
            <Encoding>UTF-8</Encoding>
            <layout class="ch.qos.logback.classic.PatternLayout">
                
                <pattern>
                    %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{
       5} - %msg%n
                </pattern>
            </layout>
        </appender>
    
    
        
        <appender name="monitorAppender"

        </appender>
        <logger name="monitor" level="INFO">

        </logger>

以上配置文件，声明了四种类型的日志输入类型，并按照小时自动回滚日志。
