spring-boot-actuator-client 用于向 actuator 的server 暴露自己的基础信息和运行，包括线程数，堆栈，等等。。。spring-boot-admin 用于界面展示这些信息。

一个server 多个client

1.Spring Boot Admin 简介
官方原话：

codecentric’s Spring Boot Admin is a community project to manage and monitor your Spring Boot ® applications. The applications register with our Spring Boot Admin Client (via HTTP) or are discovered using Spring Cloud ® (e.g. Eureka, Consul). The UI is just a Vue.js application on top of the Spring Boot Actuator endpoints.

大概意思：

Spring Boot Admin是一个社区项目，用于管理和监视基于SpringBoot的应用程序。客户端应用可以通过Spring Boot Admin Client或者注册中心就可以注册到Spring Boot Admin服务端进行监控。Spring Boot Admin 是在 Spring Boot Actuator 的基础上提供简洁的可视化 WEB UI。2.X版本使用Vue.js重写了UI界面，简洁。

下面进入实战，搭建服务端与客户端：

2.Spring Boot Admin Server 服务端搭建

2.1 创建一个Springboot项目，基于2.1.6版本，添加相关依赖，pom:

<?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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.stwen</groupId>
    <artifactId>springboot-admin-server</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot-admin-server</name>
    <description>Demo project for Spring Boot</description>
 
    <properties>
        <java.version>1.8</java.version>
    </properties>
 
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
 
        <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-server</artifactId>
            <version>2.1.6</version>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>
 
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
 
</project>

2.2 启动类添加相关注解，@EnableAdminServer：

package com.stwen.admin.server;
 
import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
@EnableAdminServer
public class SpringbootAdminServerApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(SpringbootAdminServerApplication.class, args);
    }
 
}

2.3 修改application.yml配置文件,端口可以自己修改:

server:
  port: 8888
spring:
  application:
    name: SpringBootAdmin
  boot:
    admin:
      ui:
        title: SpringBootAdmin-Server

2.4 启动服务端应用：

springboot oauth2密码模式认证授权_spring

启动成功后，访问localhost:8888 ,就可以看到简洁的界面，现在还没有客户端注册上来，所以显示0：

springboot oauth2密码模式认证授权_springboot_02

3. Spring Boot Admin Client 客户端搭建

3.1 同样创建一个Springboot 应用，基于2.1.6版本,pom依赖如下：

<?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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.stwen</groupId>
    <artifactId>springboot-admin-client</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot-admin-client</name>
    <description>Demo project for Spring Boot</description>
 
    <properties>
        <java.version>1.8</java.version>
    </properties>
 
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
 
        <!-- 监控：Spring Boot Admin 用于监控基于 Spring Boot 的应用，它是在 Spring Boot Actuator 的基础上提供简洁的可视化 WEB UI-->
        <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-client</artifactId>
            <version>2.1.6</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
 
    </dependencies>
 
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
 
</project>

3.2 启动类不用修改，修改配置文件application.yml:

server:
  port: 9999
 
spring:
  boot:
    admin:
      client:
        # server地址
        url: http://localhost:8888
        instance:
          #client地址
          service-base-url: http://localhost:${server.port}
  application:
    name: SpringBootAdmin-Client
 
#Actuator配置：暴露敏感路径，默认情况下，敏感路径并不暴露
management:
  endpoints:
    web:
      exposure:
        # 暴露xxx端点，如需暴露多个，用,分隔；如需暴露所有端点，用'*'
        include: "*"
  endpoint:
    health:
      # 是否展示健康检查详情
      show-details: ALWAYS
 
# info信息会显示到SpringBootAdmin的server端，这里取的是pom文件中的数据
info:
  version: @project.version@
  groupId: @project.groupId@
  artifactId: @project.artifactId@

3.3 启动客户端应用，显示已注册上,选项内容挺丰富的，具体自己运行去看下：

springboot oauth2密码模式认证授权_maven_03

springboot oauth2密码模式认证授权_spring_04

springboot oauth2密码模式认证授权_springboot_05

这里可以看到具体实例的JVM内存情况：

springboot oauth2密码模式认证授权_springboot_07

4. 集成SpringCloud Discovery

如果你的应用程序使用了注册中心Spring Cloud Discovery，则不需要SBA Client客户端依赖。只需将SpringBootAdmin Server 服务端注册到注册中心即可，其余的自动配置完成。

4.1 修改上面 Spring Boot Admin Server 的pom,增加注册中心依赖，根据自己需要选择Eureka、Zookeeper、Consul等：

<!-- eureka注册中心-->
        <!--        <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
                </dependency>-->
 
        <!--ZK注册中心-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            <version>2.1.1.RELEASE</version>
            <!-- 2.1.1依赖zk为3.5.3,不兼容3.4.x,注册不上-->
            <exclusions>
                <exclusion>
                    <groupId>org.apache.zookeeper</groupId>
                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.14</version>
        </dependency>
 
        <!-- Consul注册中心 -->
        <!--<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>-->

4.2 在启动类中增加多服务注册的注解 @EnableDiscoveryClient：

package com.stwen.admin;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
 
@SpringBootApplication
@EnableDiscoveryClient
@EnableAdminServer
public class SpringbootAdminClient2Application {
 
    public static void main(String[] args) {
        SpringApplication.run(SpringbootAdminClient2Application.class, args);
    }
 
}

4.3 修改application.yml ,增加多注册信息：

server:
  port: 8888
spring:
  application:
    name: SpringBootAdmin
  boot:
    admin:
      ui:
        title: SpringBootAdmin-Server
  cloud:
    zookeeper:
      #zk 注册中心
      connectString: localhost:2181
 
# eureka注册中心
#eureka:
#  client:
#    serviceUrl:
#      defaultZone: http://localhost:1001/eureka/
 
#Actuator配置：暴露敏感路径，默认情况下，敏感路径并不暴露
management:
  endpoints:
    web:
      exposure:
        # 暴露xxx端点，如需暴露多个，用,分隔；如需暴露所有端点，用'*'
        include: "*"
  endpoint:
    health:
      # 是否展示健康检查详情
      show-details: ALWAYS
