Spring Boot Admin 监控集成，naocs作为注册中心

### Server端 ###

1.添加依赖

<dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-server</artifactId>
        <version>2.1.4</version>
    </dependency>

2.启动类添加@EnableAdminServer 注解，有注册中心的话需要把该服务添加到注册服务，以便发现其他服务

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

3.yml配置

spring:
      application:
        name: admin-server
      cloud:
        nacos:
          discovery:
            server-addr: localhost:8848
    server:
      port: 7777

### Client端 ###

1.添加依赖

<dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-client</artifactId>
        <version>2.1.4</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

2.添加服务发现注解

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

3.在yml中配置以下参数，注意boot.admin.client.url 必须以http://开头，不然注册不上

spring:
      application:
        name: admin-client
      boot:
        admin:
          client:
            url: http://localhost:7777
            instance:
              prefer-ip: true #  使用IP注册
              service-base-url: http://localhost:${server.port} # 防止当ip为内网时无法注册
      # 我这里使用了nacos作为注册中心
      cloud:
        nacos:
          discovery:
            server-addr: localhost:8848
    # 默认只公开了/health和/info端点，要想暴露所有端点只需设置成星号即可
    management:
      endpoints:
        web:
          exposure:
            include: "*"
      endpoint:
        health:
          show-details: ALWAYS

启动admin-server 和admin-client，访问localhost:7777

注册成功，但是会发现注册实例的信息各不相同，有ip,有localhost,有主机名。

所以需要在spring.boot.admin.client.instance中配置你所需要的。
