**maven工程集成logback日志框架主要分为以下三步：**

# 一、新建一个空的maven 工程，并引入以下logback日志框架依赖： #

在pom加入以下依赖坐标：

<properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <logback.version>1.1.7</logback.version>
            <slf4j.version>1.7.21</slf4j.version>
        </properties>
    
        <dependencies>
            <dependency>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
                <version>${slf4j.version}</version>
                <scope>compile</scope>
            </dependency>
            <dependency>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-core</artifactId>
                <version>${logback.version}</version>
            </dependency>
            <dependency>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-classic</artifactId>
                <version>${logback.version}</version>
            </dependency>
        </dependencies>

# 二、在resources目录下新建logback配置文件 #

logback.xml的配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
    <configuration debug="false">
        
        <property name="LOG_HOME" value="./logs/" />
        
        <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="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <FileNamePattern>${LOG_HOME}/logs-stuy.log.%d{yyyy-MM-dd}.log</FileNamePattern>
                
                <MaxHistory>30</MaxHistory>
            </rollingPolicy>
            <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>
            
            <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
                <MaxFileSize>10MB</MaxFileSize>
            </triggeringPolicy>
        </appender>
    
    
        
        <root level="INFO">
            <appender-ref ref="STDOUT" />
            <appender-ref ref="FILE" />
        </root>
    </configuration>

# 三、新建日志测试类 #

一定注意不要导错包了呀

import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    /** * @业务描述： * @package_name： PACKAGE_NAME * @project_name： logs-study * @author： ratelfu@qq.com * @copyright (c) ratelfu 版权所有 */
    public class LogBackTest { 
        private static final Logger logger = LoggerFactory.getLogger(LogBackTest.class);
    
        public static void main(String[] args) { 
            logger.debug("这是debug");
            logger.info("这是info");
            logger.warn("这是warn");
            logger.error("这是error");
        }
    }

运行这个测试类则会在项目的根路径下按天生成日志文件
