spring boot（三）logback日志配置

来源：互联网发布：2016淘宝标题优化技巧编辑：程序博客网时间：2024/06/04 18:35

spring boot中默认继承了logback的日志配置。

配置application.properties

# config logbacklogging.config=classpath:logback-spring.xmllogging.path=../webLog/demo-1.0.0logging.level.root=info

logging.path可以是相对路径，也可以是绝对路径
logging.config是logback的配置路径

添加loaback的配置文件 logback-spring.xml

<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>

logback的配置文件请自行百度。
这样在具体的class中使用
private Logger logger = LoggerFactory.getLogger(getClass());
就可以打印出日志啦。
