Spring-Boot-Admin(服务监控)

版本说明

SpringBoot3.0 + SpringBootAdmin3.0.Y-->测试发现监控中心服务端无法监控服务端自身服务，安全配
置存在类和方法找不到的问题，后来将版本改为SpringBoot2.7 + SpringBootAdmin2.7.Y-->问题解决。

监控配置

@Configuration
@EnableAdminServer
public class AdminServerConfig {

    @Lazy
    @Bean(name = TaskExecutionAutoConfiguration.APPLICATION_TASK_EXECUTOR_BEAN_NAME)
    @ConditionalOnMissingBean(Executor.class)
    public ThreadPoolTaskExecutor applicationTaskExecutor(TaskExecutorBuilder builder) {
        return builder.build();
    }

}

安全配置

@EnableWebSecurity
public class SecurityConfig {

    private final String adminContextPath;

    public SecurityConfig(AdminServerProperties adminServerProperties) {
        this.adminContextPath = adminServerProperties.getContextPath();
    }

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity httpSecurity) throws Exception {
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter("redirectTo");
        successHandler.setDefaultTargetUrl(adminContextPath + "/");

        return httpSecurity
                .headers().frameOptions().disable()
                .and().authorizeRequests()
                .antMatchers(adminContextPath + "/assets/**"
                    , adminContextPath + "/login"
                    , "/actuator"
                    , "/actuator/**"
                ).permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage(adminContextPath + "/login")
                .successHandler(successHandler).and()
                .logout().logoutUrl(adminContextPath + "/logout")
                .and()
                .httpBasic().and()
                .csrf()
                .disable()
                .build();
    }

}

监控通知

被监控的服务上线或者下线将触发监控通知，可在此处发邮件或者短信通知相关运维人员。

@Slf4j
@Component
public class CustomNotifier extends AbstractEventNotifier {

    protected CustomNotifier(InstanceRepository repository) {
        super(repository);
    }

    @Override
    @SuppressWarnings("all")
    protected Mono<Void> doNotify(InstanceEvent event, Instance instance) {
        return Mono.fromRunnable(() -> {
            // 实例状态改变事件
            if (event instanceof InstanceStatusChangedEvent) {
                String registName = instance.getRegistration().getName();
                String instanceId = event.getInstance().getValue();
                String status = ((InstanceStatusChangedEvent) event).getStatusInfo().getStatus();
                log.info("Instance Status Change: [{}],[{}],[{}]", registName, instanceId, status);
            }

        });
    }

}

监控中心

主要的功能点有：显示应用程序的监控状态、应用程序上下线监控、查看 JVM、线程
信息、可视化的查看日志以及下载日志文件、动态切换日志级别、Http 请求信息跟踪

Spring-Boot-Admin(服务监控)

项目简介

用于对 Spring Boot 应用的管理和监控。可以用来监控服务是否健康、是否在线、以及一些jvm数据等等。

Spring Boot Admin 分为服务端(spring-boot-admin-server)和客户端(spring-boot-admin-client)，
服务端和客户端之间采用 http 通讯方式实现数据交互；单体项目中需要整合 spring-boot-admin-client
才能让应用被监控。

在 SpringCloud 项目中，spring-boot-admin-server 是直接从注册中心抓取应用信息，不需要每个微服
务应用整合 spring-boot-admin-client 就可以实现应用的管理和监控。
