spring boot 日志配置详解

最近在学习spring boot框架的路上，今日看了一下spring boot日志配置，顺便留个笔记记录一下。

1.新建logback.xml文件

内容如下：

<!-- Logback configuration. See http://logback.qos.ch/manual/index.html -->
<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>

<!-- hibernate日志输入 -->
<!-- <logger name="org.hibernate.type.descriptor.sql.BasicBinder"
 level="TRACE" />
<logger name="org.hibernate.type.descriptor.sql.BasicExtractor"
 level="TRACE" />
<logger name="org.hibernate.SQL" level="INFO" />
<logger name="org.hibernate.engine.QueryParameters" level="INFO" />
<logger name="org.hibernate.engine.query.HQLQueryPlan" level="INFO" /> -->

<root level="INFO">
 <appender-ref ref="INFO_FILE" />
 <appender-ref ref="ERROR_FILE" />
</root>

</configuration>

2.然后在application.properties文件中假如如下代码：

#log
logging.config=classpath:logback.xml
logging.path=/workspace/rock/jpa-test/log

3.这时就可以使用log对象了

private final Logger log = Logger.getLogger(this.getClass());

log.info("你好");

注：由于我的项目在d盘，所以第二步设置的文件路径为：d:/workspace/rock/jpa-test/log

运行程序后，进入路径会有三个文件
