问题描述

使用SpringBootAdmin(sba)监控Springboot服务时，配置了logback日志框架，按天滚动生成日志，此时在sba的日志监控页面出现404，如下图所示：

解决方案

查看浏览器控制台以及查询sba文档可知，此处日志的显示主要是由spirngBoot的端点/actuator/logprofile控制日志显示的，因此从访问/actuator/logprofile端点开始解决。

创建一个测试项目

环境

IDEA

JDK 1.8

SpringBoot 2.3.3

引入meven依赖

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>

引入web依赖是由于/actuator/logfile端点只有在web下才会生效

修改application.yml文件

spring: application: name: actuator-logfile logging: level: root: info com.lzm: debug pattern: file: "%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%5p) %clr(${PID}){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n%wEx" file: # path: ./logs/${spring.application.name} # path和name设置一个即可，name的优先级高 name: ./logs/${spring.application.name}.logmanagement: endpoints: web: exposure: include: "*" # <1>

<1>处的代码表示开放所有的web端点，不开放的话会导致访问不到/actuator/logfile端点

访问/actuator/logfile端点

启动测试项目，浏览器输入/actuator/logfile，出现如下所示结果：

此时/actuator/logfile端点可以正常访问。

添加logback

引入logback文件如下

<?xml version="1.0" encoding="UTF-8"?> <configuration scan="true" scanPeriod="10 seconds"> <contextName>logback</contextName> <property name="log.path" value="logs" /> <property name="log.name" value="actuator-logfile" /> <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="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}" /> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <appender name="LOG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/${log.name}.log</file> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> <charset>UTF-8</charset> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${log.path}/${log.name}.%d{yyyy-MM-dd}.log</fileNamePattern> <maxHistory>1</maxHistory> </rollingPolicy> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>DEBUG</level> </filter> </appender> <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/${log.name}-error.log</file> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> <charset>UTF-8</charset>  </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${log.path}/${log.name}-error.%d{yyyy-MM-dd}.log</fileNamePattern> <maxHistory>1</maxHistory> </rollingPolicy> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <springProfile name="dev"> <root level="debug"> <appender-ref ref="CONSOLE" /> <appender-ref ref="LOG_FILE" /> <appender-ref ref="ERROR_FILE" /> </root> </springProfile>  <springProfile name="prod"> <root level="info"> <appender-ref ref="LOG_FILE" /> <appender-ref ref="ERROR_FILE" /> </root> </springProfile> <include resource="org/springframework/boot/logging/logback/console-appender.xml" /> <logger name="jdbc.sqlonly" level="OFF"></logger> <logger name="jdbc.audit" level="INFO"></logger> <logger name="jdbc.resultset" level="OFF"></logger> <logger name="jdbc.connection" level="OFF"></logger> <logger name="jdbc.sqltiming" level="OFF"> <appender-ref ref="CONSOLE" /> </logger> <logger name="org.springframework.web.servlet" level="info" /> <logger name="org.springframework.data.mongodb.core" level="DEBUG"/> </configuration>

修改logging配置

logging: level: root: info pattern: file: "%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%5p) %clr(${PID}){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n%wEx" # file: <1> # path: ./logs/${spring.application.name} # name: ./logs/${spring.application.name}.log config: classpath:logback-custom.xml <2>
