Springboot Logback日志多文件输出(按日期和大小分割)

拼搏现实的明天。 2022-12-04 15:59 1073阅读 0赞

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

--------------------

# 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

<property name="LOG_HOME" value="./applog"/>
        
        <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

<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>
        
        <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

<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。

<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][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">
          
          <fileNamePattern>mylog-%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
           
           <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][http_logback.qos.ch_manual_appenders.html_TimeBasedRollingPolicy]

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

<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。

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