一.admin服务端搭建：

1.新建一个springboot项目，版本2.3.7.RELEASE，

引入pom文件：

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

2.添加注解：

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

3.配置

yml配置文件

# 应用服务 WEB 访问端口
    
    server.port: 9999

spring:
      application:
        name: spring-boot-adminer
    # ##############boot admin 配置##############
      boot:
        admin:
          notify:
            mail:
              to: xx@qq.com
          monitor:
            info-interval: 5s
            info-lifetime: 5s
            status-interval: 5s
            status-lifetime: 5s
    # ##############安全认证配置###############
      security:
        user:
          name: admin
          password: 123456
    # ##############邮件配置##############
      mail:
        host: smtp.qq.com
        username: xx@qq.com
        password:

安全配置类：官方配置，可直接使用

@Configuration(proxyBeanMethods = false)
    class SecurityConfig extends WebSecurityConfigurerAdapter {
    
        private final AdminServerProperties adminServer;
    
        private final SecurityProperties security;
    
        public SecurityConfig(AdminServerProperties adminServer, SecurityProperties security) {
            this.adminServer = adminServer;
            this.security = security;
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
            successHandler.setTargetUrlParameter("redirectTo");
            successHandler.setDefaultTargetUrl(this.adminServer.path("/"));
    
            http.authorizeRequests(
                            (authorizeRequests) -> authorizeRequests.antMatchers(this.adminServer.path("/assets/**")).permitAll()
                                    .antMatchers(this.adminServer.path("/actuator/info")).permitAll()
                                    .antMatchers(this.adminServer.path("/actuator/health")).permitAll()
                                    .antMatchers(this.adminServer.path("/login")).permitAll().anyRequest().authenticated()
                    ).formLogin(
                            (formLogin) -> formLogin.loginPage(this.adminServer.path("/login")).successHandler(successHandler).and()
                    ).logout((logout) -> logout.logoutUrl(this.adminServer.path("/logout"))).httpBasic(Customizer.withDefaults())
                    .csrf((csrf) -> csrf.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
                            .ignoringRequestMatchers(
                                    new AntPathRequestMatcher(this.adminServer.path("/instances"),
                                            HttpMethod.POST.toString()),
                                    new AntPathRequestMatcher(this.adminServer.path("/instances/*"),
                                            HttpMethod.DELETE.toString()),
                                    new AntPathRequestMatcher(this.adminServer.path("/actuator/**"))
                            ))
                    .rememberMe((rememberMe) -> rememberMe.key(UUID.randomUUID().toString()).tokenValiditySeconds(1209600));
        }
    
        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.inMemoryAuthentication().withUser(security.getUser().getName())
                    .password("{noop}" + security.getUser().getPassword()).roles("USER");
        }
    
    }

二、客户端搭建

1.在需要被监控的应用中引入pom依赖：

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

2.客户端配置：

spring:
    # #############bootAdmin的监控配置#############
      boot:
        admin:
          client:
    # ############bootAdmin的服务端的地址和用户密码############
            url: http://localhost:9999
            username: admin
            password: 123456
            instance:
              prefer-ip: true

# springboot actuator 端点
    management:
      endpoints:
        web:
          exposure:
    # ##############开放所有端点##############
            include: '*'
      endpoint:
        health:
    # ##############显示监控的详细信息##############
          show-details: always

三、基于微服务注册中心的方式配置：admin-server会自动从注册中心拉取各个服务的信息进行监控，就不需要在每个服务服务节点单独进行配置了。

1.注册中心服务搭建

假设使用的是eureka注册中心，则注册中心服务引入pom依赖：

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

yml配置：

spring:
      application:
        name: eureka-server
    server:
      port: 8761
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8761/eureka
        register-with-eureka: false
        fetch-registry: false
    management:
      endpoints:
        web:
          exposure:
            include: "*"
      endpoint:
        health:
          show-details: ALWAYS

2.admin-server更改配置

引入新的pom依赖：

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

yml配置文件中添加配置：

eureka:
      client:
        registryFetchIntervalSeconds: 5
        service-url:
          defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/
      instance:
        leaseRenewalIntervalInSeconds: 10
        health-check-url-path: /actuator/health
    　　 metadata-map: 
    　　　　user.name: ${spring.security.user.name} 
    　　　　user.password: ${spring.security.user.password}
    
    management:
      endpoints:
        web:
          exposure:
            include: "*"
      endpoint:
        health:
          show-details: ALWAYS

启动类添加注解：*@EnableDiscoveryClient*

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