SpringBoot Admin應用監控搭建

簡介

Spring Boot Admin 用於監控基於 Spring Boot 的應用，它是在 Spring Boot Actuator 的基礎上提供簡潔的可視化 WEB UI。

參考手冊地址：http://codecentric.github.io/spring-boot-admin/2.1.1/

Spring Boot Admin 是由服務端Server和客戶端Client組成

• 服務端
• 1.建立一個springboot工程並添加如下依賴

   1 <dependencies>
   2      <dependency>
   3          <groupId>org.springframework.boot</groupId>
   4          <artifactId>spring-boot-starter-web</artifactId>
   5      </dependency>
   6 
   7      <dependency>
   8          <groupId>de.codecentric</groupId>
   9          <artifactId>spring-boot-admin-server</artifactId>
  10          <version>2.1.1</version>
  11      </dependency>
  12 
  13      <dependency>
  14          <groupId>de.codecentric</groupId>
  15          <artifactId>spring-boot-admin-server-ui</artifactId>
  16          <version>2.1.1</version>
  17      </dependency>
  18 
  19      <dependency>
  20          <groupId>org.springframework.boot</groupId>
  21          <artifactId>spring-boot-starter-security</artifactId>
  22       </dependency>
  23 </dependencies>

• 2.重寫權限控制類(非必要)

   1 @Configuration  2 public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {  3     private final String adminContextPath;  4 
   5     public SecuritySecureConfig(AdminServerProperties adminServerProperties) {  6         this.adminContextPath = adminServerProperties.getContextPath();  7  }  8 
   9  @Override 10     protected void configure(HttpSecurity http) throws Exception { 11         SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler(); 12         successHandler.setTargetUrlParameter("redirectTo"); 13         successHandler.setDefaultTargetUrl(adminContextPath + "/monitor"); 14 
  15  http.authorizeRequests() 16                 .antMatchers(adminContextPath + "/assets/**").permitAll() 17                 .antMatchers(adminContextPath + "/login").permitAll() 18  .anyRequest().authenticated() 19  .and() 20                 .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and() 21                 .logout().logoutUrl(adminContextPath + "/logout").and() 22  .httpBasic().and() 23  .csrf() 24  .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()) 25  .ignoringAntMatchers( 26                         adminContextPath + "/instances", 27                         adminContextPath + "/actuator/**"
  28  ); 29  } 30 }

   1 @EnableWebSecurity  2 public class WebSecurityConfig implements WebMvcConfigurer {  3 
   4  @Bean  5     public UserDetailsService userDetailsService() throws Exception {  6         InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();  7         manager.createUser(User.withDefaultPasswordEncoder().username("root").password("root").roles("administrator").build());  8         return manager;  9  } 10 }

• 3.啓動類添加註解@EnableAdminServer

  1 @SpringBootApplication 2 @EnableAdminServer 3 public class AdminServerApplication{ 4 
  5     public static void main(String[] args) { 6         SpringApplication.run(AdminServerApplication.class, args); 7  } 8 }

• 4.配置application.yml

  1 server: 2  port: 8081 3  
  4 spring: 5  boot: 6  admin: 7       context-path: monitor

• 5.瀏覽器訪問該項目
• 客戶端
  • 1.在須要被監控的應用裏面添加以下依賴(注意版本號要與server端相同)

    1 <dependency>
    2       <groupId>de.codecentric</groupId>
    3       <artifactId>spring-boot-admin-starter-client</artifactId>
    4       <version>2.1.1</version>
    5 </dependency>

  • 2.編輯配置文件（詳細屬性配置參考手冊）

    1 spring.boot.admin.client.url = http://localhost:8081/admin-server/monitor
    2 spring.boot.admin.client.username = root 3 spring.boot.admin.client.password = root
    4 spring.boot.admin.client.instance.service-base-url=http://localhost:8080
    5 spring.boot.admin.client.instance.name = dida 6 
    7 management.endpoints.web.exposure.include = *
    8 management.endpoint.health.show-details = ALWAYS

• 刷新服務端

問題記錄

 　　按照上面的操做，我把公司的一個項目配置成了客戶端。在個人win10系統電腦上面運行這兩個程序是沒有問題的。可是當實際部署在linux服務器上面的時候就遇到了問題：我把springbootAdmin的server端部署到了linux服務器（服務器1），把要監控的項目部署到了另外一臺Linux服務器（服務器2），這兩臺服務器處於同一個局域網內。運行這兩個項目，發現程序server端可以發現這個個人client項目，可是client項目一直處於斷開狀態。

 錯誤日誌

WARN  de.codecentric.boot.admin.client.registration.ApplicationRegistrator.register Line:115 - Failed to register application as Application

通過屢次嘗試，發現spring.boot.admin.client.url 該項目配置應該配置ip地址 http://172.18.0.188:8080/monitor，而不是域名。
