logback.xml動態配置程序路徑的操作
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"/> <!-- 該值由啟動程序時候動態傳入 --> <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>${LOG_PATTERN}</pattern> <immediateFlush>true</immediateFlush> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <root level="info"> <appender-ref ref="STDOUT"/> <appender-ref ref="FILE"/> <appender-ref ref="ERRORFILE"/> </root> </configuration>
property標簽由name和value組成,上邊定義的name可以在下邊通過${name}引用。
value的值可以直接在xml中寫死,也可以通過程序啟動時候通過jvm虛擬機參數配置來傳入,比如此處是-DSUB_LOG_HOME=xxx。
idea中配置:
2.spring boot應用
spring boot應用中將logback-spring.xml放置在resources目錄,內容如下:
<?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="${logPath}"/> <!-- 該值由啟動程序時候動態傳入 --> <property name="SUB_LOG_HOME" value="${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>
該配置文件中除瞭使用<property>還使用瞭<springProperty>其中source為引用的spring配置中的變量,比如此處是logback.logPath和logback.subLogPath這兩個值的傳入可以通過spring boot配置文件傳入,也可以通過程序啟動時候動態傳入,比如–logback.subLogPath=xxx
補充:logback.xml 自動讀取日志存儲路徑
文件的命名和加載順序有關logback.xml早於application.yml加載,logback-spring.xml晚於application.yml加載
如果logback配置需要使用application.yml中的屬性,需要命名為logback-spring.xml
logback使用application.yml中的屬性
使用springProperty才可使用application.yml中的值 可以設置默認值

以上為個人經驗,希望能給大傢一個參考,也希望大傢多多支持WalkonNet。如有錯誤或未考慮完全的地方,望不吝賜教。
