一、说明

Spring Boot Admin是一个开源社区项目，用于管理和监控SpringBoot应用程序。

二、新建一个 Spring Boot Admin Server

1、先新建一个 client ，向服务注册中心注册，然后添加依赖

        <!-- spring boot admin server -->
        <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-server</artifactId>
            <version>2.0.3</version>
        </dependency>

注意版本号

这里的版本号需要注意一下

2、添加配置文件

spring:
  application:
    name: sc-admin-server
server:
  port: 8768
eureka:
  client:
    registryFetchIntervalSeconds: 5
    service-url:
      defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS

3、启动类添加注解 @EnableAdminServer

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

/**
 * 加上 @EnableAdminServer 注解，开启 admin server 的功能
 */

@SpringBootApplication
@EnableAdminServer
@EnableEurekaClient
public class ScAdminServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ScAdminServerApplication.class, args);
    }

}

三、新建一个 Spring Boot Admin Client

1、先新建一个 client ，向服务注册中心注册，然后添加依赖

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

这里的版本号也需要注意一下

2、修改配置文件

spring:
  application:
    name: sc-admin-client
eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health
    # 为了在服务注册中心里显示实际的 IP 地址，需添加下面的配置
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true
  client:
    registryFetchIntervalSeconds: 5
    service-url:
      defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS
server:
  port: 8762

四、启动 Eureka Server、Spring Boot Admin Server、Spring Boot Admin Client

eureka server

访问 Spring Boot Admin Server http://localhost:8768/

spring boot admin server

五、补充

1、版本

2、配置文件

3、功能
