如果对slf4j有不太了解的，可以参考本人另外一片文章[日志框架之2 slf4j+logback实现日志架构][2 slf4j_logback]

## 实现 ##

### 添加依赖 ###

<dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.25</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <version>1.2.3</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.2.3</version>
    </dependency>

### 修改配置文件 ###

在resources下面创建logback.xml配置文件

<?xml version="1.0" encoding="utf-8"?>
    <configuration scan="true" scanPeriod="1 seconds" debug="true">
    
        <timestamp key="byDay" datePattern="yyyy-MM-dd"/>
        <timestamp key="byHour" datePattern="yyyyMMdd_HH"/>
        <timestamp key="byMinute" datePattern="yyyyMMdd'T'HH:mm"/>
        <timestamp key="bySecond" datePattern="yyyyMMdd'T'HHmmss"/>
    
        <property name="pattern" value="%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} [%file:%line] - %msg%n"/>
        <property name="charsetEncoding" value="UTF-8"/>
    
        
        <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>${pattern}</pattern>
                <charset>${charsetEncoding}</charset>
            </encoder>
        </appender>
    
        
        <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>./logback/mylog.log</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>./logback/mylog.%d{yyyy-MM-dd_HH}.log</fileNamePattern>
                <maxHistory>30</maxHistory>
                <totalSizeCap>3GB</totalSizeCap>
            </rollingPolicy>
    
            <encoder>
                <pattern>${pattern}</pattern>
            </encoder>
        </appender>
    
        
        <root level="debug">
            <appender-ref ref="console"/>
            <appender-ref ref="file"/>
        </root>
    </configuration>

### 代码实现 ###

新建TestLogger.java

public class TestLogger { 
        private static final Logger _logger = LoggerFactory.getLogger(TestLogger.class) ;
        public static void main(String[] args) {
            for(int i=0;i<10;i++){
                _logger.info("服务器日志{}",i);
            }
        }
    }

## 运行 ##

运行TestLogger.java文件，效果如图
