SpringBoot-Admin 服務監控

簡單介紹

Spring Boot Actuator 是 Spring Boot 自帶的一個功能模組,
提供了一組已經開箱即用的生產環境下常用的特性和服務,比如應用程式的健康檢查、資訊暴露、度量收集、紀錄檔記錄等。
在實際專案中,Actuator 可以幫助我們快速瞭解應用程式的執行狀態和效能瓶頸。

整合SpringBoot-Admin監控,Spring Boot Admin 就是將 Spring Boot Actuator中提供的endpoint資訊視覺化展示。

環境

Springboot: 2.1.1.RELEASE

注意:不同的SpringBoot版本,所用到的依賴會不一致。本版本親測可用哦。

伺服器端簡單搭建

核心依賴


<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-server</artifactId>
    <version>2.1.6</version>
</dependency>

<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-server-ui-login</artifactId>
    <version>1.5.7</version>
</dependency>

啟動類


@EnableAdminServer //開啟admin伺服器端
@SpringBootApplication
public class BootAdminServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(BootAdminServerApplication.class, args);
    }

}

組態檔

server:
  port: 8001
  servlet:
    context-path: /admin-server
spring:
  application:
    name: admin-server

啟動服務後,存取:http://localhost:8001/admin-server

安全認證

核心依賴


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

SecuritySecureConfig 攔截器Code


@EnableWebSecurity
@Configuration
public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {

    private final String adminContextPath;

    public SecuritySecureConfig(AdminServerProperties adminServer) {
        this.adminContextPath = adminServer.getContextPath();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter("redirectTo");
        successHandler.setDefaultTargetUrl(adminContextPath + "/");

        http.authorizeRequests()
                .antMatchers(adminContextPath + "/login",
                        adminContextPath + "/assets/**",
                        adminContextPath + "/manage/**",
                        adminContextPath + "/actuator/**",
                        adminContextPath + "/login.html"
                ).permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler)
                .and()
                .logout().logoutUrl(adminContextPath + "/logout")
                .and()
                .httpBasic()
                .and()
                .csrf().disable();
    }

}

修改設定

新增以下設定

spring:
  security:
    user:
      name: admin
      password: admin

啟動服務後,存取:http://localhost:8001/admin-server

輸入使用者名稱,密碼即可。

如何實現服務 告警通知

當我們的服務發生異常時, 可以通過郵件、微信、釘釘等傳送告警資訊。

Server 端新增以下設定類。

@Component
public class AdminNotifier extends AbstractStatusChangeNotifier {

    private static final Logger log = LoggerFactory.getLogger(AdminNotifier.class);

    /**
     * 訊息模板
     */
    private static final String template = "<<<%s>>> \n 【服務名】: %s(%s) \n 【狀態】: %s(%s) \n 【服務ip】: %s \n 【詳情】: %s";

    private String titleAlarm = "系統告警";

    private String titleNotice = "系統通知";

    private String[] ignoreChanges = new String[]{"UNKNOWN:UP", "DOWN:UP", "OFFLINE:UP"};

    public AdminNotifier(InstanceRepository repository) {
        super(repository);
    }

    @Override
    protected boolean shouldNotify(InstanceEvent event, Instance instance) {
        if (!(event instanceof InstanceStatusChangedEvent)) {
            return false;
        } else {
            InstanceStatusChangedEvent statusChange = (InstanceStatusChangedEvent) event;
            String from = this.getLastStatus(event.getInstance());
            String to = statusChange.getStatusInfo().getStatus();
            return Arrays.binarySearch(this.ignoreChanges, from + ":" + to) < 0 && Arrays.binarySearch(this.ignoreChanges, "*:" + to) < 0 && Arrays.binarySearch(this.ignoreChanges, from + ":*") < 0;
        }
    }

    @Override
    protected Mono<Void> doNotify(InstanceEvent event, Instance instance) {

        return Mono.fromRunnable(() -> {

            if (event instanceof InstanceStatusChangedEvent) {
                log.info("Instance {} ({}) is {}", instance.getRegistration().getName(),
                        event.getInstance(),
                        ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus());
                String status = ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus();
                String messageText = null;
                switch (status) {
                    // 健康檢查沒通過
                    case "DOWN":
                        log.info("傳送 健康檢查沒通過 的通知!");
                        messageText = String
                                .format(template, titleAlarm, instance.getRegistration().getName(), event.getInstance(),
                                        ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus(), "健康檢查沒通過通知",
                                        instance.getRegistration().getServiceUrl(), JSONObject.toJSONString(instance.getStatusInfo().getDetails()));
                        log.info(messageText);
                        break;
                    // 服務離線
                    case "OFFLINE":
                        log.info("傳送 服務離線 的通知!");
                        messageText = String
                                .format(template, titleAlarm, instance.getRegistration().getName(), event.getInstance(),
                                        ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus(), "服務離線通知",
                                        instance.getRegistration().getServiceUrl(), JSONObject.toJSONString(instance.getStatusInfo().getDetails()));
                        log.info(messageText);
                        break;
                    //服務上線
                    case "UP":
                        log.info("傳送 服務上線 的通知!");
                        messageText = String
                                .format(template, titleNotice, instance.getRegistration().getName(), event.getInstance(),
                                        ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus(), "服務上線通知",
                                        instance.getRegistration().getServiceUrl(), JSONObject.toJSONString(instance.getStatusInfo().getDetails()));
                        log.info(messageText);
                        break;
                    // 服務未知異常
                    case "UNKNOWN":
                        log.info("傳送 服務未知異常 的通知!");
                        messageText = String
                                .format(template, titleAlarm, instance.getRegistration().getName(), event.getInstance(),
                                        ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus(), "服務未知異常通知",
                                        instance.getRegistration().getServiceUrl(), JSONObject.toJSONString(instance.getStatusInfo().getDetails()));
                        log.info(messageText);
                        break;
                    default:
                        break;
                }
            } else {
                log.info("Instance {} ({}) {}", instance.getRegistration().getName(), event.getInstance(),
