Spring Boot Admin 服务端

创建 Spring Boot Admin Server

创建一个工程名为 hello-spring-cloud-admin 的项目，pom.xml 文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <dependencies>
        <!-- Spring Boot Begin -->
        <dependency>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

主要增加了 2 个依赖，org.jolokia:jolokia-core、de.codecentric:spring-boot-admin-starter-server

<dependency>
    <groupId>org.jolokia</groupId>
    <artifactId>jolokia-core</artifactId>
</dependency>
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-server</artifactId>
</dependency>

其中 spring-boot-admin-starter-server 的版本号为：2.0.0，这里没写版本号是因为我已将版本号托管到 dependencies 项目中

#Application

通过 @EnableAdminServer 注解开启 Admin 功能

package com.snake.hello.spring.cloud.admin;

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;

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

#application.yml

设置端口号为：8084

spring:
  application:
    name: hello-spring-cloud-admin
  zipkin:
    base-url: http://localhost:9411

server:
  port: 8084

management:
  endpoint:
    health:
      show-details: always
  endpoints:
    web:
      exposure:
        # 注意：此处在视频里是 include: ["health", "info"] 但已无效了，请修改
        include: health,info

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

主要增加了 Spring Boot Admin Server 的相关配置

management:
  endpoint:
    health:
      show-details: always
  endpoints:
    web:
      exposure:
        # 注意：此处在视频里是 include: ["health", "info"] 但已无效了，请修改
        include: health,info

#测试访问监控中心

打开浏览器访问：http://localhost:8084 会出现以下界面
