Sring Boot Admin 2.1.6一看就会的配置查看日志

## 背景 ##

因为公司的项目查看日志，需要连服务器跳机，再跳到各自部署的服务器上才能查看日志，很不方便，所以就想搞一个Spring Boot Admin（SBA） 来查看日志。  
[官网文档地址][Link 1]

最开始的时候，我全部都用的最新版，springboot 2.3.0.RELEASE ，SBA 2.2.3, spring cloud Hoxton.SR4，然而查看日志功能始终404，搞了我两天 [404问题描述][404]；百度，google都找了一下，关于2.2.3的SBA是少之又少，能查看日志的几乎没有。

## 解决 ##

最后我妥协了，换了个2.1.6版本（springboot 2.1.0.RELEASE ，SBA 2.1.6, spring cloud Finchley.SR2 ，可通过[Spring Initializr][]来验证版本兼容问题），再将client的配置稍改一下就解决了，而且这一改版本，还解决了2.2.3的一个问题，client重启时，server端不刷新client的状态。

因为是结合注册中心来做的，所以先上eureka的配置

## eureka-server ##

**pom.xml**

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>

**application.xml**

spring:
      application:
        name: eureka-server
    server:
      port: 8761
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8761/eureka
        register-with-eureka: false
        fetch-registry: false

**启动类(加上@EnableEurekaServer)**

@SpringBootApplication
    @EnableEurekaServer
    public class EurekaApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(EurekaApplication.class, args);
        }
    
    }

## admin-server ##

**pom.xml**

<properties>
         <java.version>1.8</java.version>
         <spring-boot-admin.version>2.1.6</spring-boot-admin.version>
         <spring-cloud.version>Finchley.SR2</spring-cloud.version>
     </properties>

<dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-server</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>

**application.yml**

spring:
      application:
        name: admin-server
    
    server:
      port: 8080
    eureka:
      client:
        registryFetchIntervalSeconds: 5
        service-url:
          defaultZone: http://localhost:8761/eureka/
      instance:
        leaseRenewalIntervalInSeconds: 10
        health-check-url-path: /actuator/health

admin-server启动类(加上  
**@EnableEurekaClient  
@EnableAdminServer**  
这两个注解  
)

@SpringBootApplication
    @EnableEurekaClient
    @EnableAdminServer
    public class AdminServerApplication { 
        public static void main(String[] args) { 
            SpringApplication.run(AdminServerApplication.class, args);
        }
    }

## admin-client ##

最关键的配置莫过于客户端  
**pom.xml**

<dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-web</artifactId>
     </dependency>
     <dependency>
         <groupId>de.codecentric</groupId>
         <artifactId>spring-boot-admin-starter-client</artifactId>
     </dependency>
     <dependency>
         <groupId>org.springframework.cloud</groupId>
         <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
     </dependency>

**application.yml**

spring:
      application:
        name: admin-customer1
    server:
      port: 8081
    eureka:
      client:
        registryFetchIntervalSeconds: 5
        service-url:
          defaultZone: http://localhost:8761/eureka/
      instance:
        leaseRenewalIntervalInSeconds: 10
        health-check-url-path: /actuator/health
    
    management:
      endpoints:
        web:
          exposure:
            include: "*" #暴露所有端点，默认只暴露health和info
          # CORS跨域支持
          cors:
            allowed-origins: "*"
            allowed-methods: GET,POST
      endpoint:
        health:
          show-details: ALWAYS
    
    logging:
      file: logs/output.log # 这个地方输入日志配置里的输出路径，如果不填，页面上则不显示logging-logfile模块，如果填错找不到，则报404
      # 2.2.x之后是logging.file.path 
      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"
        #输出日志格式

**启动类**

@SpringBootApplication
    @EnableEurekaClient
    public class AdminCustomer1Application { 
        public static void main(String[] args) { 
            SpringApplication.run(AdminCustomer1Application.class, args);
        }
    }

在application.yml平级创建**logback-spring.xml**，因为SpringBoot官方是推荐这个命名方式。

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
               <property name="APP_Name" value="adminTest" /> 
        　　　<contextName>${APP_Name}</contextName>
            
            
            <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="adminTest >> ${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(LN:%L){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}" />
            
               
            <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
                <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> 
                    <pattern>${CONSOLE_LOG_PATTERN}</pattern>
                    <charset>utf8</charset>
                </encoder> 
            </appender>
            
               
            <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
                
                <file>logs/output.log</file>   
                <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                    
                    <FileNamePattern>logs/output-%d{ yyyy-MM-dd}.log</FileNamePattern> 
                    
                    <MaxHistory>15</MaxHistory>
                </rollingPolicy>   
                <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> 
                     
                    <pattern>%d{ yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{ 50}:%L - %msg%n</pattern>   
                </encoder> 
            </appender>
    
            
            <root level="INFO">
                <appender-ref ref="STDOUT" />
                <appender-ref ref="FILE" />
            </root>
            </configuration>

这样就全部搭建好了，启动看效果，先启eureka，其他模块随意。
