SpringBoot整合Spring Boot Admin实现服务监控

Spring Boot Admin用于管理和监控一个或多个Spring Boot服务，其分为Server端和Client端，Server端相当于一个注册中心，Client端通过Http请求向Server端进行注册，也可以结合Eureka、Nacos等注册中心实现服务注册。

1. Server端服务开发 1.1. 引入核心依赖

<dependency>    <groupId>de.codecentric</groupId>    <artifactId>spring-boot-admin-starter-server</artifactId>    <version>2.3.1</version></dependency><dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-security</artifactId></dependency><dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-web</artifactId></dependency>

1.2. application.yml配置文件

server:  port: 8138  servlet:    context-path: /adminspring:  application:    name: springboot-admin-server  security:    user:      name: admin      password: 123456

1.3. Security配置文件

@Configurationpublic class SecurityConfig extends WebSecurityConfigurerAdapter {    private String adminSecurityContextPath;    public SecurityConfig(AdminServerProperties adminServerProperties) {        this.adminSecurityContextPath = adminServerProperties.getContextPath();    }    @Override    protected void configure(HttpSecurity http) throws Exception {        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();        successHandler.setTargetUrlParameter("redirectTo");        http.authorizeRequests()                .antMatchers(adminSecurityContextPath + "/assets/**").permitAll()                .antMatchers(adminSecurityContextPath + "/login").permitAll()                .anyRequest().authenticated()                .and()                .formLogin().loginPage(adminSecurityContextPath + "/login").successHandler(successHandler)                .and()                .logout().logoutUrl(adminSecurityContextPath + "/logout")                .and()                .httpBasic()                .and()                .csrf()                .ignoringAntMatchers(adminSecurityContextPath + "/instances", adminSecurityContextPath + "/actuator/**")                .disable();    }}

1.4. 主启动类

@EnableAdminServer@SpringBootApplicationpublic class AdminServerApplication {    public static void main(String[] args) {        SpringApplication.run(AdminServerApplication.class, args);    }}

2. Client端服务开发 2.1. 引入核心依赖

<dependency>    <groupId>de.codecentric</groupId>    <artifactId>spring-boot-admin-starter-client</artifactId>    <version>2.3.1</version></dependency><dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-web</artifactId></dependency>

2.2. application.yml配置文件

server:  port: 8238spring:  application:    name: springboot-admin-client  boot:    admin:      client:        url: http://localhost:8138/admin        instance:          prefer-ip: true        username: admin        password: 123456management:  endpoints:    web:      exposure:        include: '*'  endpoint:    health:      show-details: always    shutdown:      enabled: true    logfile:      external-file: ./logs/log_file.loglogging:  config: classpath:logback-spring.xml  level:    com.xlhj.boot.admin: debuginfo:  author: caijliu  projectName: springboot整合springboot admin  version: 1.0

2.3. logback-spring.xml文件

<?xml version="1.0" encoding="UTF-8" ?><configuration>    <property name="log.path" value="./logs"/>    <!--彩色日志依赖的渲染类-->    <conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter"/>    <conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />    <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />    <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>    <include resource="org/springframework/boot/logging/logback/file-appender.xml"/>    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">        <encoder>            <pattern>${CONSOLE_LOG_PATTERN}</pattern>            <charset>UTF-8</charset>        </encoder>    </appender>    <!--配置日志输出到文件-->    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">        <file>${log.path}/log_file.log</file>        <encoder>            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>            <charset>UTF-8</charset>        </encoder>        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">            <!-- 每天日志归档路径以及格式 -->            <FileNamePattern>${log.path}/log_file-%d{yyyy-MM-dd}-%i.log</FileNamePattern>            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">                <maxFileSize>10MB</maxFileSize>            </timeBasedFileNamingAndTriggeringPolicy>            <!--日志文件保留天数-->            <maxHistory>15</maxHistory>        </rollingPolicy>    </appender>    <logger name="com.xlhj.boot.admin" level="info"/>    <root level="info">        <appender-ref ref="console"/>        <appender-ref ref="file"/>    </root></configuration>

2.4. 主启动类

@SpringBootApplicationpublic class AdminClientApplication {    private static Logger logger = LoggerFactory.getLogger(AdminClientApplication.class);    public static void main(String[] args) {        SpringApplication.run(AdminClientApplication.class, args);        logger.info("服务启动成功,当前时间为:{}", LocalDateTime.now());        logger.error("服务启动成功,当前时间为:{}", LocalDateTime.now());    }}

3. 验证

分别启动Server和Client服务，在浏览器输入地址：http://localhost:8138/admin

输入用户名和密码：admin/123456，登陆成功后，可以看到如下页面

点击该服务可以进入具体的监控页面，注意需要点击下图箭头所指位置

点击进入服务后，可以看到如下信息

将滚动条往下拉，可以看到内存、线程等信息

选择日志—>日志文件可以查看到服务的日志信息

点击日志配置可以动态调节每个包/类的日志级别

选择应用墙选项，可以查看到应用有哪些服务被监控

4. 配置邮件告警

Spring Boot Admin还可以对其监控的服务提供告警功能，当出现重大故障，如服务宕机时，可以及时以邮件方式通知运维人员

4.1. 引入核心依赖

在Server服务中引入邮件依赖

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

4.2. application.yml

在yml配置文件中加入如下配置信息

spring:  mail:    host: smtp.qq.com    username: xxxxx@qq.com    password: 授权码  boot:    admin:      notify:        mail:          to: 收件人邮箱          from: 发件人邮箱

4.3. 通知配置文件

@Configurationpublic class NotificationConfig {    private InstanceRepository instanceRepository;    private ObjectProvider<List<Notifier>> provider;    public NotificationConfig(InstanceRepository instanceRepository, ObjectProvider<List<Notifier>> provider) {        this.instanceRepository = instanceRepository;        this.provider = provider;    }    @Bean    public FilteringNotifier filteringNotifier() {        CompositeNotifier compositeNotifier = new CompositeNotifier(this.provider.getIfAvailable(Collections::emptyList));        return new FilteringNotifier(compositeNotifier, this.instanceRepository);    }    @Bean    @Primary    public RemindingNotifier remindingNotifier() {        RemindingNotifier remindingNotifier = new RemindingNotifier(filteringNotifier(), this.instanceRepository);        //配置每隔多久提示        remindingNotifier.setReminderPeriod(Duration.ofMinutes(1));        //配置每隔多久检查        remindingNotifier.setCheckReminderInverval(Duration.ofSeconds(10));        return remindingNotifier;    }}

4.4. 验证

先将Client服务关闭，稍等一会便会收到宕机提示邮件

再次将Client服务启动
