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：

#loglogging.config=classpath:logback.xmllogging.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
