Springboot logback-spring.xml无法加载
现象
SpringBoot项目,启动后,日志文件没有出现在logback-spring.xml指定的目录下
且启动日志开头如下:
"C:\Program Files\Java\jdk1.8.0_144\bin\java"...
Connected to the target VM, address: '127.0.0.1:52494', transport: 'socket'
18:34:58,011 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]

logback-spring.xml文件一直未改动过,如下:
<?xml version="1.0" encoding="UTF-8"?> <Configuration status="INFO"> <springProperty scope="context" name="logPath" source="log.path"/> <springProperty scope="context" name="logLevel" source="log.level"/> <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern> %d{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] %logger{36} %line - %msg%n</pattern> </layout> </appender> <appender name="fileLog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!--滚动策略--> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!--输出路径--> <fileNamePattern>${logPath}/server.%d.log</fileNamePattern> </rollingPolicy> <encoder> <pattern> %d{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] %logger{36} %line - %msg%n</pattern> <charset>UTF-8</charset> </encoder> </appender> <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <!--滚动策略--> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!--输出路径--> <fileNamePattern>${logPath}/server.%d.error</fileNamePattern> </rollingPolicy> <encoder> <pattern> %d{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] %logger{36} %line - %msg%n</pattern> <charset>UTF-8</charset> </encoder> </appender> <root level="${logLevel}"> <appender-ref ref="consoleLog"/> <appender-ref ref="fileLog"/> <appender-ref ref="fileErrorLog"/> </root> </Configuration>
原因分析
1.配置文件位置正确
classes/ ├── application.properties ├── com │ └── nero │ └── test │ ├── api │ │ ├── Api.class
2.分析启动日志,分析可能是依赖的jar中有logback.xml配置,冲突导致的问题
解决方案
在application.properties中加入配置:
logging.config=classpath:logback-spring.xml
通过该配置,强制指定日志的配置文件,问题得以解决
springboot logback-spring.xml 配置, 使用不同配置文件中的配置
application.yml
spring: profiles: active: prod # active 哪一个配置文件
application-dev.yml
logging: file: path: d:/var/log
application-prod.yml
logging: file: path: /var/log/question
logback-spring.xml
<?xml version="1.0" encoding="UTF-8"?> <configuration scan="true" scanPeriod="60 seconds" debug="false"> <contextName>wechat-service</contextName> <!-- !!!!!!!!!获取 application-{xxx}.yml 的配置 !!!!!--> <springProperty scope="context" name="log.path" source="logging.file.path"/> <!--<property name="log.path" value="log" />--> <property name="log.maxHistory" value="15" /> <property name="log.colorPattern" value="%d{yyyy-MM-dd HH:mm:ss} | %highlight(%-5level) | %boldYellow(%thread) | %boldGreen(%logger) | %msg%n"/> <property name="log.pattern" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n" /> <!--输出到控制台--> <appender name="console" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${log.colorPattern}</pattern> </encoder> </appender> <!--输出到文件 info 级别的 log--> <appender name="file_info" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${log.path}/info/info.%d{yyyy-MM-dd}.log</fileNamePattern> <MaxHistory>${log.maxHistory}</MaxHistory> </rollingPolicy> <encoder> <pattern>${log.pattern}</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>INFO</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <!--输出到文件 error 级别的 log--> <appender name="file_error" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${log.path}/error/error.%d{yyyy-MM-dd}.log</fileNamePattern> </rollingPolicy> <encoder> <pattern>${log.pattern}</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <root level="debug"> <appender-ref ref="console" /> </root> <root level="info"> <appender-ref ref="file_info" /> <appender-ref ref="file_error" /> </root> </configuration>
从application-xxx.yml 中拿配置
<springProperty scope="context" name="log.path" source="logging.file.path"/>
