SpringBoot使用admin+actuator实现日志可视化的方法
作者：天宇_任
如何在SpringBoot中使用Admin和Actuator实现日志可视化,需配置pom依赖、yml参数及logback路径,确保两者一致,启动服务后通过指定端口访问日志界面,并检查404错误原因,感兴趣的朋友一起看看吧
1：创建admin服务端
pom文件依赖如下
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-server</artifactId>
<version>2.3.1</version>
</dependency>yml配置如下
server: port: 8081
management:
trace:
http:
enabled: true
endpoints:
web:
exposure:
include: "*"
endpoint:
health:
show-details: always如果需要注册到nacos或者其他注册中心，可以按需添加
启动类需要加上
@EnableAdminServer注解启动
2：服务端配置
pom配置如下
dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
<version>2.3.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.3.7.RELEASE</version>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-client</artifactId>
<version>2.3.1</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
<version>2.3.7.RELEASE</version>
</dependency>yml配置如下
server:
port: 8080 # 微服务端口
spring:
application:
name: clientServer # 服务名称
boot:
admin:
client:
url: http://localhost:8081 # Admin Server地址logging:
config: classpath:logback-spring.xml
file:
name: logs/clientServer/debug.log
pattern:
file: "%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n"
management:
endpoints:
web:
exposure:
include: "*" # 暴露所有Actuator端点（生产环境建议按需配置）
endpoint:
health:
show-details: always
logfile:
external-file: ${logging.file.name}
enabled: truelogback-spring中的地址要和yml地址一致，例：
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="false">
<springProperty scop="context" name="spring.application.name" source="spring.application.name" defaultValue=""/>
<property name="log.path" value="logs/clientServer" />
<!-- 彩色日志格式 -->
<property name="CONSOLE_LOG_PATTERN"
value="${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${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}" />
<!-- 彩色日志依赖的渲染类 -->
<conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter" />
<conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />
<conversionRule conversionWord="wEx"
converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />
<!-- Console log output -->
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>${CONSOLE_LOG_PATTERN}</pattern>
</encoder>
</appender>
<!-- Log file debug output -->
<appender name="debug" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${log.path}/debug.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>${log.path}/%d{yyyy-MM}/debug.%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
<maxFileSize>50MB</maxFileSize>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date [%thread] %-5level [%logger{50}] %file:%line - %msg%n</pattern>
</encoder>
</appender>
<!-- Log file error output -->
<appender name="error" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${log.path}/error.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>${log.path}/%d{yyyy-MM}/error.%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern>
<maxFileSize>50MB</maxFileSize>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date [%thread] %-5level [%logger{50}] %file:%line - %msg%n</pattern>
</encoder>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>
</appender>
<!-- Level: FATAL 0 ERROR 3 WARN 4 INFO 6 DEBUG 7 -->
<root level="INFO">
<appender-ref ref="console" />
<appender-ref ref="debug" />
<appender-ref ref="error" />
</root>
</configuration>启动服务端，打开http://localhost:8081/
就可以看到注册进去的服务了
点击对应的服务名可以看到服务对应的日志
如果日志页面报错404，一定要检查yml配置的日志路径和logback-spring.xml中的路径是否一致
