怎么在logback.xml中动态配置程序路径?相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。
1.普通java程序
如下配置的logback.xml
<?xml version="1.0" encoding="UTF-8"?><configuration> <property name="LOGS_HOME" value="/opt/program/app/logback-demo/logs"/> <!-- 该值由启动程序时候动态传入 --> <property name="SUB_LOG_HOME" value="" /> <property name="LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{25} - %msg%n"/> <property name="LOG_CHARSET" value="UTF-8"/> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${LOG_PATTERN}</pattern> <charset>${LOG_CHARSET}</charset> </encoder> </appender> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${LOGS_HOME}/${SUB_LOG_HOME}/logback-demo.log</file> <encoder> <pattern>${LOG_PATTERN}</pattern> <charset>${LOG_CHARSET}</charset> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${LOGS_HOME}/${SUB_LOG_HOME}/logback-demo-%d{yyyy-MM-dd}.log</fileNamePattern> <maxHistory>30</maxHistory> </rollingPolicy> </appender> <appender name="ERRORFILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${LOGS_HOME}/${SUB_LOG_HOME}/logback-demo.error.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${LOGS_HOME}/${SUB_LOG_HOME}/logback-demo-%d{yyyy-MM-dd}.error.log</fileNamePattern> <maxHistory>20</maxHistory> </rollingPolicy> <encoder> <pattern>${LOG_PATTERN}</pattern> <immediateFlush>true</immediateFlush> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <root level="info"> <appender-ref ref="STDOUT"/> <appender-ref ref="FILE"/> <appender-ref ref="ERRORFILE"/> </root> </configuration>
property标签由name和value组成,上边定义的name可以在下边通过${name}引用。
value的值可以直接在xml中写死,也可以通过程序启动时候通过jvm虚拟机参数配置来传入,比如此处是-DSUB_LOG_HOME=xxx。
idea中配置:
2.spring boot应用
spring boot应用中将logback-spring.xml放置在resources目录,内容如下:
<?xml version="1.0" encoding="UTF-8"?><configuration xmlns="http://ch.qos.logback/xml/ns/logback" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://ch.qos.logback/xml/ns/logback http://ch.qos.logback/xml/ns/logback/logback.xsd" debug="true" scan="false" scanPeriod="30 seconds"> <springProperty scope="context" name="logPath" source="logback.logPath"/> <springProperty scope="context" name="subLogPath" source="logback.subLogPath"/> <!--spring-boot-1.5.10.RELEASE.jar!/org/springframework/boot/logging/logback/defaults.xml--> <conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter" /> <conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" /> <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" /> <property name="LOG_HOME" value="${logPath}"/> <!-- 该值由启动程序时候动态传入 --> <property name="SUB_LOG_HOME" value="${subLogPath}" /> <property name="LOG_NAME" value="data-middleware-server-realtime"/> <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39} %line){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/> <property name="FILE_LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{25} %line - %msg%n"/> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${CONSOLE_LOG_PATTERN}</pattern> </encoder> </appender> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${LOG_HOME}/${SUB_LOG_HOME}/${LOG_NAME}.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/${SUB_LOG_HOME}/${LOG_NAME}.log-%d{yyyy-MM-dd}.%i.zip</fileNamePattern> <maxHistory>20</maxHistory> <maxFileSize>100MB</maxFileSize> </rollingPolicy> <encoder> <pattern>${FILE_LOG_PATTERN}</pattern> <immediateFlush>true</immediateFlush> </encoder> </appender> <appender name="ERRORFILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${LOG_HOME}/${SUB_LOG_HOME}/${LOG_NAME}.error.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/${SUB_LOG_HOME}/${LOG_NAME}.error.log-%d{yyyy-MM-dd}.%i.zip</fileNamePattern> <maxHistory>20</maxHistory> <maxFileSize>100MB</maxFileSize> </rollingPolicy> <encoder> <pattern>${FILE_LOG_PATTERN}</pattern> <immediateFlush>true</immediateFlush> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <appender name="REALTIME_IMPORT_APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${LOG_HOME}/${SUB_LOG_HOME}/import/${LOG_NAME}.log</file> <encoder> <pattern>${FILE_LOG_PATTERN}</pattern> <immediateFlush>true</immediateFlush> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/${SUB_LOG_HOME}/import/${LOG_NAME}-%d{yyyy-MM-dd}.log</fileNamePattern> <maxHistory>7</maxHistory> </rollingPolicy> </appender> <logger name="REALTIME_IMPORT_LOGGER" level="INFO" additivity="false"> <appender-ref ref="REALTIME_IMPORT_APPENDER"/> </logger> <logger name="org.apache.zookeeper.ZooKeeper" level="WARN" additivity="true"></logger> <logger name="org.apache.zookeeper.ClientCnxn" level="WARN" additivity="true"></logger> <root level="DEBUG"> <appender-ref ref="STDOUT"/> <appender-ref ref="FILE"/> <appender-ref ref="ERRORFILE"/> </root></configuration>
该配置文件中除了使用<property>还使用了<springProperty>其中source为引用的spring配置中的变量,比如此处是logback.logPath和logback.subLogPath这两个值的传入可以通过spring boot配置文件传入,也可以通过程序启动时候动态传入,比如--logback.subLogPath=xxx
补充:logback.xml 自动读取日志存储路径
文件的命名和加载顺序有关logback.xml早于application.yml加载,logback-spring.xml晚于application.yml加载
如果logback配置需要使用application.yml中的属性,需要命名为logback-spring.xml
logback使用application.yml中的属性
使用springProperty才可使用application.yml中的值 可以设置默认值
<?xml version="1.0" encoding="UTF-8"?><configuration> <!-- 说明: 1. 文件的命名和加载顺序有关 logback.xml早于application.yml加载,logback-spring.xml晚于application.yml加载 如果logback配置需要使用application.yml中的属性,需要命名为logback-spring.xml 2. logback使用application.yml中的属性 使用springProperty才可使用application.yml中的值 可以设置默认值 --> <springProperty scope="context" name="logName" source="ruoyi.logPath" defaultValue="default"/> <property name="log.path" value="${logName}" /> <!-- 日志存放路径 --><!-- <property name="log.path" value="D:/zmSmartClassroom/logs"/>--> <!-- <property name="log.path" value="/home/zmSmartClassroom/logs"/>--> <!-- 日志输出格式 --> <property name="log.pattern" value="%d{HH:mm:ss.SSS} [%thread] %-5level %logger{20} - [%method,%line] - %msg%n"/> <!-- 控制台输出 --> <appender name="console" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${log.pattern}</pattern> </encoder> </appender> <!-- 系统日志输出 --> <appender name="file_info" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/sys-info.log</file> <!-- 循环政策:基于时间创建日志文件 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 日志文件名格式 --> <fileNamePattern>${log.path}/sys-info.%d{yyyy-MM-dd}.log</fileNamePattern> <!-- 日志最大的历史 60天 --> <maxHistory>60</maxHistory> </rollingPolicy> <encoder> <pattern>${log.pattern}</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <!-- 过滤的级别 --> <level>INFO</level> <!-- 匹配时的操作:接收(记录) --> <onMatch>ACCEPT</onMatch> <!-- 不匹配时的操作:拒绝(不记录) --> <onMismatch>DENY</onMismatch> </filter> </appender> <appender name="file_error" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/sys-error.log</file> <!-- 循环政策:基于时间创建日志文件 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 日志文件名格式 --> <fileNamePattern>${log.path}/sys-error.%d{yyyy-MM-dd}.log</fileNamePattern> <!-- 日志最大的历史 60天 --> <maxHistory>60</maxHistory> </rollingPolicy> <encoder> <pattern>${log.pattern}</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <!-- 过滤的级别 --> <level>ERROR</level> <!-- 匹配时的操作:接收(记录) --> <onMatch>ACCEPT</onMatch> <!-- 不匹配时的操作:拒绝(不记录) --> <onMismatch>DENY</onMismatch> </filter> </appender> <!-- 用户访问日志输出 --> <appender name="sys-user" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/sys-user.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 按天回滚 daily --> <fileNamePattern>${log.path}/sys-user.%d{yyyy-MM-dd}.log</fileNamePattern> <!-- 日志最大的历史 60天 --> <maxHistory>60</maxHistory> </rollingPolicy> <encoder> <pattern>${log.pattern}</pattern> </encoder> </appender> <!-- 系统模块日志级别控制 --> <logger name="com.ruoyi" level="info"/> <!-- Spring日志级别控制 --> <logger name="org.springframework" level="warn"/> <root level="info"> <appender-ref ref="console"/> </root> <!--系统操作日志--> <root level="info"> <appender-ref ref="file_info"/> <appender-ref ref="file_error"/> </root> <!--系统用户操作日志--> <logger name="sys-user" level="info"> <appender-ref ref="sys-user"/> </logger></configuration>
