Spring Boot Admin 用于管理和监控一个或者多个Spring Boot应用， Spring Boot Admin 分为Server端和Client端，Client通过http向Server端注册， 也可以结合Spring Cloud 的服务注册组件Eureka 进行注册。
SpringAdmin 的监测详细信息有如下：
- 显示健康状况
- JVM和内存指标
- micrometer.io指标
- 数据源指标
- 缓存指标
- 显示构建信息编号
- 关注并下载日志文件
- 查看jvm系统和环境属性
- 查看Spring Boot配置属性
- 支持Spring Cloud的postable / env-和/ refresh-endpoint
- 轻松的日志级管理
- 与JMX-beans交互
- 查看线程转储
- 查看http跟踪
- 查看auditevents
- 查看http-endpoints
- 查看计划任务
- 查看和删除活动会话（使用spring-session）
- 查看Flyway / Liquibase数据库迁移
- 下载heapdump
- 状态变更通知（通过电子邮件，Slack，Hipchat，……）
- 状态更改的事件日志（非持久性）
本文的所有工程的Spring Boot版本为2.2.2.RELEASE，SpringBootAdmin版本为2.2.1。
搭建Spring Boot Admin
搭建Spring Boot Admin Server
- 工程依赖如下：web，admin-server
<properties>
<java.version>1.8</java.version>
<spring-boot-admin.version>2.2.1</spring-boot-admin.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-server</artifactId>
</dependency>
</dependencies>
- 在工程的启动类AdminServerApplication加上@EnableAdminServer注解，开启AdminServer的功能
@SpringBootApplication
@EnableAdminServer
public class AdminServerApplication {
public static void main(String[] args) {
SpringApplication.run(AdminServerApplication.class, args);
}
}
- 在工程的配置文件application.yml中配置程序名和程序的端口，代码如下：
spring:
application:
name: admin-server
server:
port: 8769
这样Admin Server就创建好了。
创建Spring Boot Admin Client
- 工程依赖如下：web，admin-client
<properties>
<java.version>1.8</java.version>
<spring-boot-admin.version>2.2.1</spring-boot-admin.version>
</properties>
<dependencies>
<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.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>
- 配置文件application.yml中配置应用名和端口信息，以及向admin-server注册的地址为http://localhost:8769，最后暴露自己的actuator的所有端口信息，具体配置如下：
spring:
application:
name: admin-client
boot:
admin:
client:
url: http://localhost:8769
server:
port: 8768
management:
endpoints:
web:
exposure:
include: '*'
endpoint:
health:
show-details: ALWAYS
- 项目启动文件如下：
@SpringBootApplication
public class AdminClientApplication {
public static void main(String[] args){
SpringApplication.run(AdminClientApplication.class,args);
}
}
到此，SpringBoot-Admin-Client 工程创建完成。
启动Admin-Server，Admin-Client两个工程，在浏览器上输入localhost:8769 ，浏览器显示的界面如下：

点击wallboard，可以查看admin-client具体的信息，比如内存状态信息：

更多监控信息，自己体验。
SpringBoot Admin 结合Eureka注册中心使用
搭建Eureka注册中心
- 工程依赖如下：eureka-server
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Hoxton.SR1</spring-cloud.version>
</properties>
<dependencies>
<dependency>

<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
- 配置eureka-server的端口信息，以及defaultZone和防止自注册。最后系统暴露eureka-server的actuator的所有端口。
spring:
application:
name: eureka-server
server:
port: 8761
eureka:
client:
service-url:
defaultZone: http://localhost:8761/eureka
register-with-eureka: false
fetch-registry: false
management:
endpoints:
web:
exposure:
include: "*"
endpoint:
health:
show-details: always
- 在工程的启动文件EurekaServerApplication 加上@EnableEurekaServer注解开启Eureka Server.
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args){
SpringApplication.run(EurekaServerApplication.class,args);
}
}
eureka-server搭建完毕。
搭建admin-server

- 配置：配置admin-server的应用名、端口信息。并向注册中心注册，注册地址为http://localhost:8761，最后将actuator的所有端口暴露出来，配置如下：
spring:
application:
name: admin-server
server:
port: 8769
eureka:
client:
service-url:
defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/
instance:
leaseRenewalIntervalInSeconds: 10

@SpringBootApplication
@EnableAdminServer
@EnableDiscoveryClient
public class AdminServerApplication {
public static void main(String[] args) {
SpringApplication.run(AdminServerApplication.class, args);
}
}
到此admin-server 搭建完成。
搭建admin-client

- 在工程的配置文件配置应用名、端口、向注册中心注册的地址，以及暴露actuator的所有端口。
spring:
application:
name: admin-client
server:
port: 8762
eureka:
instance:
lease-renewal-interval-in-seconds: 10
# health-check-url-path: /actuator/health
client:
registry-fetch-interval-seconds: 5
service-url:
defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/
management:
endpoints:
web:
exposure:
include: '*'
endpoint:
health:
show-details: ALWAYS
- 在启动类加上@EnableDiscoveryClient注解，开启DiscoveryClient的功能。
@SpringBootApplication
@EnableDiscoveryClient
public class AdminClientApplication {
public static void main(String[] args) {
SpringApplication.run( AdminClientApplication.class, args );
}
}
到此，Eureka-Server,Admin-Server-Eureka-Client，Admin-Client-Eureka-Cleint 三个工程搭建完成
启动三个工程，在浏览器上访问localhost:8769，浏览器会显示和上一小节一样的界面。

Admin-Server集成spring security
在2.1.0版本中去掉了hystrix dashboard，登录界面默认集成到了spring security模块，只要加上spring security就集成了登录模块。
- 只需要改变下admin-server工程，需要在admin-server工程的pom文件引入以下的依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
- 在admin-server工的配置文件application.yml中配置spring security的用户名和密码，这时需要在服务注册时带上metadata-map的信息，如下：
spring:
security:
user:
name: "admin"
password: "admin"
eureka:
instance:
metadata-map:
user.name: ${spring.security.user.name}
user.password: ${spring.security.user.password}
- 写一个配置类SecuritySecureConfig继承WebSecurityConfigurerAdapter，配置如下：
@Configuration
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
private final String adminContextPath;
public SpringSecurityConfig(AdminServerProperties adminServerProperties) {
this.adminContextPath = adminServerProperties.getContextPath();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
successHandler.setTargetUrlParameter("redirectTo");
http.authorizeRequests()
.antMatchers(adminContextPath + "/assets/**").permitAll()
.antMatchers(adminContextPath + "/login").permitAll()
.antMatchers("/systemConfig/**").permitAll()
.antMatchers("/serveConfig/**").permitAll()
// .antMatchers("/admin/instances/*/actuator/metrics/process.uptime").permitAll()
.antMatchers("/admin/instances/*/actuator/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and()
.logout().logoutUrl(adminContextPath + "/logout").and()
.httpBasic().and()
.csrf().disable();
}
}
重启启动工程，在浏览器上访问：http://localhost:8769/，会被重定向到登录界面，登录的用户名和密码为配置文件中配置的，分别为admin和admin，界面显示如下：
