本文將以Spring Boot Admin 2.0 與 Eureka整合展示Spring Boot Admin 2.0 的使用。
下面我介紹一下使用到的相關(guān)應(yīng)用：

服務(wù) 端口 服務(wù)說(shuō)明

ljx-eureka               1025       服務(wù)注冊(cè)與發(fā)現(xiàn)中心
ljx-user-service          8083      用戶微服務(wù)（監(jiān)控客戶端）
ljx-springcloud-sbaserver 8085      spring boot admin監(jiān)控服務(wù)（監(jiān)控服務(wù)端）

這里我主要講解spring boot admin服務(wù)端與客戶端的搭建，服務(wù)注冊(cè)發(fā)現(xiàn)的搭建不再做贅述。

服務(wù)端admin搭建

pom.xml

         <artifactId>spring-boot-admin-starter-server</artifactId>
         <version>2.0.4</version>
     </dependency>
     <!--JMX-bean 管理-->

         <artifactId>spring-boot-starter-web</artifactId>
         <exclusions>
             <!--排除tomcat依賴 -->
             <exclusion>
                 <artifactId>spring-boot-starter-tomcat</artifactId>
                 <groupId>org.springframework.boot</groupId>
             </exclusion>
         </exclusions>
     </dependency>
     <!--undertow容器 -->

     <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-security</artifactId>
     </dependency>

啟動(dòng)類

@SpringBootApplication
@EnableAdminServer
@EnableEurekaClient
public class SbaServerApplication extends SpringBootServletInitializer {
   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
       return builder.sources(SbaServerApplication.class);
   }
   public static void main( String[] args )
   {
       SpringApplication.run(SbaServerApplication.class,args);
   }
}

安全控制

這里我們給springBootAdmin增加一個(gè)安全控制悲龟，增加登錄頁(yè)面

 /**
     * 安全控制
     */
    @Profile("secure")
    @Configuration
    public static class SecuritySecureConfig extends WebSecurityConfigurerAdapter {
        private final String adminContextPath;
 
        public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
            this.adminContextPath = adminServerProperties.getContextPath();
        }
 
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            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();
            // @formatter:on
        }
    }

bootstrap.yml配置

server:
  port: 8085
  servlet:
      context-path: /sbaserver  #給服務(wù)增加上下文 前綴
spring:
  application:
    name: ljx-springcloud-sbaserver
  profiles:
    active: 
      - secure
      
# 注冊(cè)中心配置
eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10 #表示eureka client發(fā)送心跳給server端的頻率，默認(rèn)為30秒
    prefer-ip-address: true
    instance-id: ljx-springcloud-sbaserver8085
    health-check-url-path: /sbaserver/actuator/health #健康檢查的地址（依賴spring-boot-starter-actuator）
  client:
    registryFetchIntervalSeconds: 5 #表示eureka client間隔多久去拉取服務(wù)注冊(cè)信息树碱，默認(rèn)為30秒
    service-url:
      defaultZone: http://jiaxing:jiaxing@localhost:1025/eureka/
      
# 暴露監(jiān)控端點(diǎn) springBootAdmin2 只暴露了兩個(gè)
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: ALWAYS  #health endpoint是否必須顯示全部細(xì)節(jié)记罚。默認(rèn)情況下, /actuator/health 是公開(kāi)的，并且不顯示細(xì)節(jié)
---
spring:
  profiles: insecure

---
#配置登錄名望迎，密碼和安全策略
spring:
  profiles: secure
  security:
    user:
      name: 'jiaxing'
      password: 'jiaxing'
eureka:
  instance:
    metadata-map:
      user.name: ${spring.security.user.name}        #These two are needed so that the server
      user.password: ${spring.security.user.password} #can access the protected client endpoints

啟動(dòng)

由上圖可看出服務(wù)均已注冊(cè)到eureka障癌，我們直接點(diǎn)開(kāi)(localhost:8085/sbaserver)

看到上圖說(shuō)明，服務(wù)端已配置成功辩尊。

客戶端搭建ljx-user-server

pom.xml

     <!--監(jiān)控客戶端-->
        <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-client</artifactId>
            <version>2.0.4</version>
         </dependency>
    <!--監(jiān)控-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

bootstrap.yml配置

server:
  port: 8082
spring:
  application:
    name: ljx-user-service
# 注冊(cè)中心配置
eureka:
  instance:
    metadata-map:
      management:
        context-path: /actuator
    health-check-url: http://localhost:${server.port}/actuator/health
    status-page-url: http://localhost:${server.port}/actuator/info
    home-page-url: http://localhost:${server.port}
    prefer-ip-address: true
    instance-id: ljx-user-service8082
  client:
    service-url:
      defaultZone: http://jiaxing:jiaxing@ljx-eureka:1025/eureka/

info:
  version: 1.0.0

# 暴露監(jiān)控端點(diǎn)
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: ALWAYS

完成上面一系列配置涛浙，我們登錄后可以看到下面的頁(yè)面可以說(shuō)是配置部署成功了
在這里可以看到每個(gè)連接的時(shí)長(zhǎng)，以及版本等
