SpringBoot学习笔记之日志处理

今天药忘吃喽~ 2022-06-08 08:17 222阅读 0赞

spring boot内部使用Commons Logging来记录日志，但也保留外部接口可以让一些日志框架来进行实现，例如Java Util Logging,Log4J2还有Logback。如果你想用某一种日志框架来进行实现的话，就必须先配置，默认情况下，spring boot使用Logback作为日志实现的框架。

$\{LOG\_PATH\}, Spring Boot配置文件中logging.path的值

配置logging.level.\*来具体输出哪些包的日志级别

logging.level.root=INFO

logging.level.org.springframework.web=DEBUG

logging.level.org.hibernate=ERROR

将日志输出到文件中

logging.path=D:\\\\demo

logging.file=demo.log

logging.level.root=info

推荐采用下面的方式

\#日志配置

logging.config=classpath:logback.xml

logging.path=D:/java/logs

logback.xml 内容如下：

<configuration scan="true" scanPeriod="10 seconds">  
    <include resource="org/springframework/boot/logging/logback/base.xml" />  
  
    <appender name="INFO\_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">  
        <File>$\{LOG\_PATH\}/info.log</File>  
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  
            <fileNamePattern>$\{LOG\_PATH\}/info-%d\{yyyyMMdd\}.log.%i</fileNamePattern>  
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">  
                <maxFileSize>500MB</maxFileSize>  
            </timeBasedFileNamingAndTriggeringPolicy>  
            <maxHistory>2</maxHistory>  
        </rollingPolicy>  
        <layout class="ch.qos.logback.classic.PatternLayout">  
            <Pattern>%d\{yyyy-MM-dd HH:mm:ss.SSS\} \[%thread\] %-5level %logger\{36\} -%msg%n  
            </Pattern>  
        </layout>  
    </appender>  
  
    <appender name="ERROR\_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">  
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">  
            <level>ERROR</level>  
        </filter>  
        <File>$\{LOG\_PATH\}/error.log</File>  
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  
            <fileNamePattern>$\{LOG\_PATH\}/error-%d\{yyyyMMdd\}.log.%i  
            </fileNamePattern>  
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">  
                <maxFileSize>500MB</maxFileSize>  
            </timeBasedFileNamingAndTriggeringPolicy>  
            <maxHistory>2</maxHistory>  
        </rollingPolicy>  
        <layout class="ch.qos.logback.classic.PatternLayout">  
            <Pattern>%d\{yyyy-MM-dd HH:mm:ss.SSS\} \[%thread\] %-5level %logger\{36\} -%msg%n  
  
            </Pattern>  
        </layout>  
    </appender>  
    <root level="INFO">  
        <appender-ref ref="INFO\_FILE" />  
        <appender-ref ref="ERROR\_FILE" />  
    </root>  
      
    <logger name="org.springframework.boot" level="DEBUG"/>  
      
</configuration>

说明：$\{LOG\_PATH\} 为application.properties中配置的logging.path
