2022-01-15 周6 ## spring cloud集成spring boot admin server 在這篇文章[Springboot集成Actuator和SpringbootAdminServer監控](http://www.hmoore.net/mangomei/deepstudy/2568509)，我們學到了在`spring boot`應用中集成`spring boot admin server`來UI化顯示`spring boot actuator`的`endpoint`數據。 那如果是spring cloud應用呢？如何將集成`spring boot admin server`來界面化顯示應用的指標數據呢？ ### card-admin-server集成spring boot admin server 1. 添加依賴 ~~~ <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-server</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> ~~~ 2. 創建啟動類，注意機上注解`@EnableAdminServer` ~~~ @EnableAdminServer @SpringBootApplication(scanBasePackages = "com.github.mg0324") public class StartupApplication { public static void main(String[] args) { SpringApplication.run(StartupApplication.class,args); } } ~~~ 3. 添加安全配置類 ~~~ @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler(); successHandler.setTargetUrlParameter("redirectTo"); successHandler.setDefaultTargetUrl("/"); http.authorizeRequests() .antMatchers("/assets/**").permitAll() .antMatchers("/login").permitAll() .anyRequest().authenticated().and() .formLogin().loginPage("/login") .successHandler(successHandler).and() .logout().logoutUrl("/logout").and() .httpBasic().and() .csrf() .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()) .ignoringAntMatchers( "/instances", "/actuator/**" ); } } ~~~ 4. 設置配置 ~~~ server: port: 8100 servlet: context-path: / spring: application: name: card-admin-server security: user: name: admin password: 123456 eureka: instance: leaseRenewalIntervalInSeconds: 10 health-check-url-path: /actuator/health metadata-map: user.name: admin user.password: 123456 client: registryFetchIntervalSeconds: 10 serviceUrl: #defaultZone: http://192.168.3.26:8761/eureka/ defaultZone: http://127.0.0.1:8761/eureka/ management: endpoint: health: show-details: always endpoints: web: exposure: include: '*' ~~~ 5. 啟動訪問  ## 總結 1. springboot應用界面顯示的是程序中使用的中間件狀態；spring cloud應用顯示的是微服務相關的組件的狀態。 2. 都是基于springboot actuator的endpoint數據做界面展示的。
