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"?>

<!-- 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">

</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>
