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>
</div>
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</div>
3.这时就可以使用log对象了
private final Logger log = Logger.getLogger(this.getClass());
log.info("你好");
</div>
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
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
