前言

此系列博客是个人在学习springBoot的学习笔记，算是一个记录吧，一方面记录学习的内容，一方面记录学习中犯下的错误。学习springBoot选择的是GitHub上一个比较著名的项目，链接如下https://github.com/xkcoding/spring-boot-demo.git。这是一个从易到难的项目，目标:完成本地实现。技术差，文笔差，学习能力差，啥都差，欢迎指正，拒绝喷人

一、要实现的demo是什么？

spring-boot 集成 spring-boot-admin 来可视化的监控 spring-boot 程序的运行状态，可以与 actuator 互相搭配使用，客户端和服务器端都有展示。注意事项：

1.新建项目是在原先的多模块项目下的其中一个模块下再新建模块。

2.父级的依赖不再粘贴，可以去翻之前的博客，然后复制到最外层的pom.xml。

3.注意端口的设置，服务器端和客户端端口不要一样，否则提示端口被占用。设置方式在yml文件中

4.服务器端都点一点，我只截了进入的页面。

5.不需要再引入actuator依赖，引入admin就会引入actuator。

二、实现步骤

1.新建项目

1.新建模块：

2.代码实现

2.1 indexController代码如下（示例）：

package com.xkcoding.admin.client.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class IndexController {
// 请求路径bai 可以为空或者/
/*eg:  在springmvc中 配置 @RequestMapping(value={"test", "test1"})如果你项目端口是8080；然后你要访问这个方法,
你可以通过 http://localhost:8080/test或者http://localhost:8080/test1来访问*/
   @GetMapping(value = {"", "/"})
   public String index() {
      return "This is a Spring Boot Admin Client.";
   }
}

2.2 SpringBootDemoAdminClientApplication启动类如下

package com.xkcoding.admin.client;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootDemoAdminClientApplication {

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

2.3 application.yml文件如下

server:
  port: 8080
  servlet:
    context-path: /demo
spring:
  application:
    # Spring Boot Admin展示的客户端项目名，不设置，会使用自动生成的随机id
    name: spring-boot-demo-admin-client
  boot:
    admin:
      client:
        # Spring Boot Admin 服务端地址
        url: "http://localhost:8000/"
        instance:
          metadata:
            # 客户端端点信息的安全认证信息
            user.name: ${spring.security.user.name}
            user.password: ${spring.security.user.password}
  security:
    user:
      name: xkcoding
      password: 123456
management:
  endpoint:
    health:
      # 端点健康情况，默认值"never"，设置为"always"可以显示硬盘使用情况和线程情况
      show-details: always
  endpoints:
    web:
      exposure:
        # 设置端点暴露的哪些内容，默认["health","info"]，设置"*"代表暴露所有可访问的端点
        include: "*"

2.4 服务器端SpringBootDemoAdminServerApplication 启动类：

package com.xkcoding.admin.server;

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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