Springboot Logback日志多文件输出(按日期和大小分割)

在早期的日志Slf4j+Log4j使用方式中,我们使用最多的就是LoggerFactory来获取一个Logger实例,logback的原理也一样。本文示例文件分割按照日志大小和日期进行分割。

目录

配置logback.xml

配置需要的propery属性

配置日志追加方式

配置日志级别

配置日志模板

logback 多日志文件操作

logback 官方按大小和时间分隔规则

日志未按照大小删除和控制文件总大小

示例效果


配置logback.xml

配置需要的propery属性

这部分可以配置到logback.properties 需要开启扫描才行,下面是直接在logback.xml配置

 <!--设置日志目录-->
    <property name="LOG_HOME" value="./applog"/>
    <!--这里需要将value改成项目名称-->
    <property name="LOG_NAME" value="patrol-mobile-service"/>

配置日志追加方式

配置appender标签包括文件生成规则,内容的输出规则等

  <!--控制台日志格式-->
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{35} | %msg%n</pattern>
        </encoder>
    </appender>
    <!-- 文件日志策略:每天生成一个日志文件,保存30天的日志文件-->
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/${LOG_NAME}.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <maxFileSize>100MB</maxFileSize>
            <maxHistory>30</maxHistory>
            <totalSizeCap>10GB</totalSizeCap>
            <cleanHistoryOnStart>true</cleanHistoryOnStart>
        </rollingPolicy>
         
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{35} | %msg%n</pattern> 
        </encoder>
    </appender>

配置日志级别

注意:日志级别不区分大小写

  <!--默认日志级别,大小写无关:TRACE, DEBUG, INFO, WARN, ERROR, ALL和OFF-->
    <root level="info">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
    </root>

配置日志模板

 logger的配置就是LoggerFactory需要的模板,只有配置了工厂获取才会生效。

  <!--业务操作日志-->
    <logger name="POSITION_LOG" level="info" additivity="false">
        <appender-ref ref="POSITION_LOG_APPENDER"/>
    </logger>
    <logger name="EVENT_LOG" level="info" additivity="false">
        <appender-ref ref="EVENT_LOG_APPENDER"/>
    </logger>
    <logger name="TRACK_LOG" level="info" additivity="false">
        <appender-ref ref="TRACK_LOG_APPENDER"/>
    </logger>
    <logger name="FILE_LOG" level="info" additivity="false">
        <appender-ref ref="FILE_LOG_APPENDER"/>
    </logger>
    <logger name="RESTART_LOG" level="info" additivity="false">
        <appender-ref ref="RESTART_LOG_APPENDER"/>
    </logger>

logback 多日志文件操作

logback 官方按大小和时间分隔规则

http://logback.qos.ch/manual/appenders.html

<configuration>
  <appender name="ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>mylog.txt</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
      <!-- rollover daily -->
      <fileNamePattern>mylog-%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
       <!-- each file should be at most 100MB, keep 60 days worth of history, but at most 20GB -->
       <maxFileSize>100MB</maxFileSize>    
       <maxHistory>60</maxHistory>
       <totalSizeCap>20GB</totalSizeCap>
    </rollingPolicy>
    <encoder>
      <pattern>%msg%n</pattern>
    </encoder>
  </appender>


  <root level="DEBUG">
    <appender-ref ref="ROLLING" />
  </root>

</configuration>

日志未按照大小删除和控制文件总大小 

参考官方说明:http://logback.qos.ch/manual/appenders.html#TimeBasedRollingPolicy

需要配置:cleanHistoryOnStart标签值为true默认是false.

<!-- 文件日志策略:每天生成一个日志文件,保存30天的日志文件-->
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/${LOG_NAME}.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <maxFileSize>100MB</maxFileSize>
            <maxHistory>30</maxHistory>
            <totalSizeCap>10GB</totalSizeCap>
            <cleanHistoryOnStart>true</cleanHistoryOnStart>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{35} | %msg%n</pattern> 
        </encoder>
    </appender>

Java日志工具类

日志枚举根据自己项目的需要进行自定义即可。

package com.patrol.beans.util;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * @Copyright: 2019-2021
 * @FileName: LoggerUtils.java
 * @Author: PJL
 * @Date: 2020/9/8 10:34
 * @Description: 日志管理工具
 */
public class LoggerUtils {

    /**
     * 打印到指定的文件下
     *
     * @param patrolLoggerType 日志文件类型
     * @return
     */
    public static Logger getLogger(PatrolLoggerType patrolLoggerType) {
        return LoggerFactory.getLogger(patrolLoggerType.getLogFileName());
    }

    /**
     * @Copyright: 2019-2021
     * @FileName: PatrolLoggerType.java
     * @Author: PJL
     * @Date: 2020/9/8 10:10
     * @Description: 巡护日志类型枚举
     */
    public enum PatrolLoggerType {
        /**
         * 重启日志
         */
        RESTART("RESTART_LOG"),
        /**
         * 实时位置
         */
        POSITION("POSITION_LOG"),
        /**
         * 用户事件
         */
        EVENT("EVENT_LOG"),
        /**
         * 用户轨迹
         */
        TRACK("TRACK_LOG"),
        /**
         * 事件附件
         */
        FILE("FILE_LOG");

        private String logFileName;

        PatrolLoggerType(String fileName) {
            this.logFileName = fileName;
        }

        public String getLogFileName() {
            return logFileName;
        }


    }
}

系统启动日志示例

在Application启动类调用日志输出。

package com.patrol.mobile;

import com.patrol.beans.util.LoggerUtils;
import org.slf4j.Logger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import javax.annotation.PostConstruct;

/**
 * 开启异步请求
 */
@EnableAsync
/**
 * 开启接口缓存
 */
@EnableCaching
/**
 * 开启定时任务调度
 */
@EnableScheduling
/**
 * 开启接口文档描述
 */
@EnableSwagger2
/**
 * @SpringBootApplication
 * <p>相当于@Configuration,@EnableAutoConfiguration和 @ComponentScan </p>
 */
@SpringBootApplication
public class PatrolMobileServiceApplication {
    /**
     * 系统重启日志输出(指定日志文件输出)
     */
    @PostConstruct
    public void printLog() {
        Logger logger = LoggerUtils.getLogger(LoggerUtils.PatrolLoggerType.RESTART);
        logger.info(">>>系统重启!");
    }

    public static void main(String[] args) {
        SpringApplication.run(PatrolMobileServiceApplication.class, args);
    }

}

示例效果
