logback.xml动态配置程序路径的操作

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"/>

<!-- 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"

<springProperty scope="context" name="logPath" source="logback.logPath"/>

<springProperty scope="context" name="subLogPath" source="logback.subLogPath"/>

<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">

</logger>

<logger name="org.apache.zookeeper.ZooKeeper" level="WARN" additivity="true"></logger>

<root level="DEBUG">

<appender-ref ref="FILE"/>

<appender-ref ref="ERRORFILE"/>

</root>

</configuration>

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>
