SpringBoot——监控中心（Admin ）

梦里梦外; 2022-04-10 13:40 285阅读 0赞

### 一、简介 ###

Spring Boot Admin是一个开源社区项目，用于管理和监控SpringBoot应用程序。 应用程序作为Spring Boot Admin Client向为Spring Boot Admin Server注册（通过HTTP）或使用SpringCloud注册中心（例如Eureka，Consul，Zookeeper）发现。 UI是的AngularJs应用程序，展示Spring Boot Admin Client的Actuator端点上的一些监控。

**常见的功能或者监控如下：**

*  显示健康状况
 *  显示详细信息，例如：JVM和内存指标、micrometer.io指标、数据源指标、缓存指标等
 *  显示构建信息编号
 *  关注并下载日志文件
 *  查看jvm系统和环境属性
 *  查看Spring Boot配置属性
 *  支持Spring Cloud的postable / env-和/ refresh-endpoint
 *  轻松的日志级管理
 *  与JMX-beans交互
 *  查看线程转储
 *  查看http跟踪
 *  查看auditevents
 *  查看http-endpoints
 *  查看计划任务
 *  查看和删除活动会话（使用spring-session）
 *  查看Flyway / Liquibase数据库迁移
 *  下载heapdump
 *  状态变更通知（通过电子邮件，Slack，Hipchat等）
 *  状态更改的事件日志（非持久性）

### 二、单独集成SpringBoot Admin ###

搭建版本：

*  Spring Boot版本为：2.1.1.RELEASE
 *  Spring Cloud版本为：Finchley.SR2
 *  Spring Boot Admin 版本为：2.1.0

parent的pom.xml文件：

<properties>
    		<java.version>1.8</java.version>
    		<spring-cloud.version>Finchley.SR2</spring-cloud.version>
    	</properties>
    
    	<dependencyManagement>
    		<dependencies>
    			<dependency>
    				<groupId>org.springframework.cloud</groupId>
    				<artifactId>spring-cloud-dependencies</artifactId>
    				<version>${spring-cloud.version}</version>
    				<type>pom</type>
    				<scope>import</scope>
    			</dependency>
    		</dependencies>
    	</dependencyManagement>

**1、搭建SpringBoot Admin Server端（admin-server）**

添加相关依赖：

在启动类添加注解@EnableAdminServer，开启AdminServer的功能：

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

在application.yml配置工程名和端口：

spring:
      application:
        name: admin-server
    server:
      port: 8081

**2、搭建SpringBoot Admin Client端（admin-client）**

添加相关依赖：

<dependency>
    			<groupId>de.codecentric</groupId>
    			<artifactId>spring-boot-admin-starter-client</artifactId>
    			<version>2.1.0</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>

在application.yml配置应用名和端口信息，以及向admin-server注册的地址为http://localhost:8081，最后暴露自己的actuator的所有端口信息：

server:
      port: 8082
    spring:
      application:
        name: admin-client
      boot:
        admin:
          client:
            url: http://localhost:8081
    management:
      endpoint:
        health:
          show-details: always
      endpoints:
        web:
          exposure:
            include: '*'

**3、分别启动admin-server和admin-client，**浏览器访问：[http://localhost:8081][http_localhost_8081]

点击wallboard可以查看admin-client具体的信息，比如内存状态信息：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3R5cDE4MDU_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3R5cDE4MDU_size_16_color_FFFFFF_t_70 2][]

查看spring bean的情况：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3R5cDE4MDU_size_16_color_FFFFFF_t_70 3][]

### 三、使用Eureka为注册中心集成 ###

SpringBoot和SpringCloud的版本和上面的一样，没有变化。

**1、搭建注册中心（eureka-server）**

添加eureka依赖：

<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    		</dependency>

在application.yml配置端口信息，以及defaultZone和防止自注册，系统暴露eureka-server的actuator的所有端口：

server:
      port: 8001
    spring:
      application:
        name: eureka-server
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8001/eureka
        register-with-eureka: false
        fetch-registry: false
    management:
      endpoint:
        health:
          show-details: always
      endpoints:
        web:
          exposure:
            include: '*'

启动类添加注解 @EnableEurekaServer，启动Eureka Server:

package com.example.demo.admin;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    
    @SpringBootApplication
    @EnableEurekaServer
    public class EurekaServerApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(EurekaServerApplication.class, args);
    	}
    
    }

**2、搭建SpringBoot Admin Server端（eureka-admin-server）**

添加依赖：

1.  引入admin-server的起步依赖、web的起步依赖、eureka-client的起步依赖；
2.  集成spring security：2.1.0版本中去掉了hystrix dashboard，登录界面默认集成到了spring security模块，只要加上spring security就集成了登录模块;
3.  集成邮箱报警功能:在spring boot admin中，也可以集成邮箱报警功能，比如服务不健康了、下线了，都可以给指定邮箱发送邮件。

<dependency>
    			<groupId>de.codecentric</groupId>
    			<artifactId>spring-boot-admin-starter-server</artifactId>
    			<version>2.1.0</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-security</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-mail</artifactId>
    		</dependency>

在application.yml配置：

1.  应用名、端口信息。并向注册中心注册，注册地址为http://localhost:8001，最后将actuator的所有端口暴露出来；
2.  配置spring security的用户名和密码，这时需要在服务注册时带上metadata-map的信息；
3.  配置邮件相关的配置，发邮件者、用户名、密码（授权码）、收件者等信息，配置邮件后，当我们已注册的客户端的状态从 UP 变为 OFFLINE 或其他状态，服务端就会自动将电子邮件发送到上面配置的地址。

server:
      port: 8002
    
    spring:
      application:
        name: eureka-admin-server
      security:
        user:
          name: "admin"
          password: "admin"
      mail:
        host: smtp.163.com
        username: typ@163.com
        password: admin #此处的密码是授权码
      boot:
        admin:
          notify:
            mail:
              to: 742354529@qq.com
    
    eureka:
      client:
        service-url:
          defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8001}/eureka/
        registry-fetch-interval-seconds: 5
      instance:
        health-check-url-path: /actuator/health
        lease-renewal-interval-in-seconds: 10
        metadata-map:
          user.name: ${spring.security.user.name}
          user.password: ${spring.security.user.password}
    
    management:
      endpoints:
        web:
          exposure:
            include: '*'
      endpoint:
        health:
          show-details: always

新建配置类SecuritySecureConfig继承WebSecurityConfigurerAdapter：

package com.example.demo.admin.config;
    
    import de.codecentric.boot.admin.server.config.AdminServerProperties;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.config.annotation.web.builders.HttpSecurity;
    import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
    import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
    
    /**
     * 路径：com.example.demo.admin.config
     * 类名：
     * 功能：《用一句描述一下》
     * 备注：
     * 创建人：typ
     * 创建时间：2019/1/11 11:05
     * 修改人：
     * 修改备注：
     * 修改时间：
     */
    @Configuration
    public class SecuritySecureConfig extends WebSecurityConfigurerAdapter{
    
        private final String adminContextPath;
    
        public SecuritySecureConfig(AdminServerProperties adminServerProperties){
            this.adminContextPath = adminServerProperties.getContextPath();
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
            successHandler.setTargetUrlParameter("redirectTo");
            http.authorizeRequests()
                    .antMatchers(adminContextPath + "/assets/**").permitAll()
                    .antMatchers(adminContextPath + "/login").permitAll()
                    .anyRequest()
                    .authenticated()
                    .and()
                    .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler )
                    .and()
                    .logout().logoutUrl(adminContextPath+"/logout")
                    .and()
                    .httpBasic()
                    .and()
                    .csrf()
                    .disable();
        }
    }

启动类添加@EnableAdminServer注解，开启admin server的功能，加上@EnableDiscoveryClient注解开启eurke client的功能：

package com.example.demo.admin;
    
    import de.codecentric.boot.admin.server.config.EnableAdminServer;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @SpringBootApplication
    @EnableAdminServer
    @EnableDiscoveryClient
    public class EurekaAdminServerApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(EurekaAdminServerApplication.class, args);
    	}
    
    }

**3、搭建SpringBoot Admin Client端（eureka-admin-client）**

添加依赖：

由于2.1.0采用webflux，引入webflux的起步依赖，引入eureka-client的起步依赖，并引用actuator的起步依赖。

<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-webflux</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-actuator</artifactId>
    		</dependency>

在application.yml配置应用名、端口、向注册中心注册的地址，以及暴露actuator的所有端口：

server:
      port: 8003
    spring:
      application:
        name: eureka-admin-client
    eureka:
      instance:
        health-check-url-path: /actuator/health
        lease-renewal-interval-in-seconds: 10
      client:
        registry-fetch-interval-seconds: 5
        service-url:
          defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8001}/eureka/
    management:
      endpoints:
        web:
          exposure:
            include: '*'
      endpoint:
        health:
          show-details: always

在启动类加上@EnableDiscoveryClie注解，开启DiscoveryClient的功能：

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

启动工程，在浏览器上访问：[http://localhost:8002/][http_localhost_8002]，登录输入配置好的用户名和密码（admin/admin）,如下显示：
