  • 【SpringBoot】Spring Boot Admin 微服务应用监控

    一、什么是Spring Boot Admin?

      Spring Boot Admin是一个开源社区项目,用于管理和监控SpringBoot应用程序。 应用程序作为Spring Boot Admin Client向为Spring Boot Admin Server注册(通过HTTP)或使用SpringCloud注册中心(例如Eureka,Consul)发现。 UI是的Vue.js应用程序,展示Spring Boot Admin Client的Actuator端点上的一些监控。服务端采用Spring WebFlux + Netty的方式。

      Spring Boot Admin为注册的应用程序提供以下功能:
    • 显示健康状况
    • 显示详细信息,例如
    • JVM和内存指标
    • micrometer.io指标
    • 数据源指标
    • 缓存指标
    • 显示构建信息编号
    • 关注并下载日志文件
    • 查看jvm system-和environment-properties
    • 查看Spring Boot配置属性
    • 支持Spring Cloud的postable / env-和/ refresh-endpoint
    • 轻松的日志级管理
    • 与JMX-beans交互
    • 查看线程转储
    • 查看http-traces
    • 查看auditevents
    • 查看http-endpoints
    • 查看计划任务
    • 查看和删除活动会话(使用spring-session)
    • 查看Flyway / Liquibase数据库迁移
    • 下载heapdump
    • 状态变更通知(通过电子邮件,Slack,Hipchat,......)
    • 状态更改的事件日志(非持久性)

    二、入门

    1. 创建 Spring Boot Admin Server

      这里我们创建一个admin-server模块来作为监控中心演示其功能。

      1.1、新建一个SpringBoot项目,

      1.2、引入spring-boot-admin-server依赖

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

      1.5、启动项目,访问地址:http://localhost:9301/

        

    2. 创建 Spring Boot Admin Server

      2.1、新建一个SpringBoot项目, 

      2.2、引入spring-boot-admin-client依赖

      2.3、编辑配置文件application.yml

     1 spring:
     2   application:
     3     name: admin-client
     4   boot:
     5     admin:
     6       client:
     7         url: http://localhost:9301 #配置admin-server地址
     8 server:
     9   port: 9305
    10 management:
    11   endpoints:
    12     web:
    13       exposure:
    14         include: '*'
    15   endpoint:
    16     health:
    17       show-details: always
    18 logging:
    19   file: admin-client.log  #添加开启admin的日志监控

      2.4、编辑启动类

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

      2.5、启动项目,继续访问admin-server的Web地址:http://localhost:9301/

        

    监控信息演示

    • 访问如下地址打开Spring Boot Admin的主页:http://localhost:9301(同上)

    • 选中admin-client客户端查看,监控信息概览



    • 度量指标信息,比如JVM、Tomcat及进程信息;


    • 环境变量信息,比如系统属性、系统环境变量以及应用配置信息;


    • 查看所有创建的Bean信息;


    • 查看应用中的所有配置信息;


    • 查看日志信息,需要添加以下配置才能开启;
      1 logging:
      2   file: admin-client.log  #添加开启admin的日志监控

    • 查看JVM信息;


    • 查看可以访问的Web端点;


    一、集成 Eureka

      1、创建Eureka服务,参考:【SpringCloud】快速入门(一)

      2、修改admin-server

        在pom.xml中添加相关依赖:

    1 <dependency>
    2     <groupId>org.springframework.cloud</groupId>
    3     <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    4 </dependency>

        在application-eureka.yml中进行配置,只需添加注册中心配置即可:

     1 spring:
     2   application:
     3     name: admin-server
     4 server:
     5   port: 9301
     6 eureka:
     7   client:
     8     register-with-eureka: true
     9     fetch-registry: true
    10     service-url:
    11       defaultZone: http://localhost:8761/eureka/

        在启动类上添加@EnableDiscoveryClient来启用服务注册功能:

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

      3、修改admin-client,

        在pom.xml中添加相关依赖:同上

        在application-eureka.yml中进行配置,只需添加注册中心配置即可,且去掉配置spring.boot.admin.client.url属性

     1 spring:
     2   application:
     3     name: admin-client
     4 #  boot:
     5 #    admin:
     6 #      client:
     7 #        url: http://localhost:9301 #配置admin-server地址
     8 server:
     9   port: 9305
    10 management:
    11   endpoints:
    12     web:
    13       exposure:
    14         include: '*'
    15   endpoint:
    16     health:
    17       show-details: always
    18 
    19 eureka:
    20   client:
    21     register-with-eureka: true
    22     fetch-registry: true
    23     service-url:
    24       defaultZone: http://localhost:8761/eureka/
    25 
    26 logging:
    27   file: admin-client.log  #添加开启admin的日志监控

        在启动类上添加@EnableDiscoveryClient来启用服务注册功能:

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

      4、功能演示

        启动Eureka注册中心,启动admin-server、admin-client

        1)查看注册中心发现服务均已注册:http://localhost:8761

        

        2)查看Spring Boot Admin 主页发现可以看到服务信息:http://localhost:9301

        

    四、集成 Spring Security

      这里我们创建一个admin-server模块来与Spring Security集成

      1、新建一个SpringBoot项目

      2、pom引入Spring Security依赖

        完整pom如下:

    65     </build>
    66 
    67 </project>
    View Code

      3、编辑配置文件application.yml

     1 spring:
     2   application:
     3     name: admin-security-server
     4   security: # 配置登录用户名和密码
     5     user:
     6       name: admin
     7       password: 123456
     8   boot:  # 不显示admin-security-server的监控信息
     9     admin:
    10       discovery:
    11         ignored-services: ${spring.application.name}
    12 
    13 server:
    14   port: 9302
    15 
    16 eureka:
    17   client:
    18     register-with-eureka: true
    19     fetch-registry: true
    20     service-url:
    21       defaultZone: http://localhost:8761/eureka/

      4、编辑主启动类

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

      5、编辑配置类

     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 + "/");
    14 
    15         http.authorizeRequests()
    16                 //1.配置所有静态资源和登录页可以公开访问
    17                 .antMatchers(adminContextPath + "/assets/**").permitAll()
    18                 .antMatchers(adminContextPath + "/login").permitAll()
    19                 .anyRequest().authenticated()
    20                 .and()
    21                 //2.配置登录和登出路径
    22                 .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and()
    23                 .logout().logoutUrl(adminContextPath + "/logout").and()
    24                 //3.开启http basic支持,admin-client注册时需要使用
    25                 .httpBasic().and()
    26                 .csrf()
    27                 //4.开启基于cookie的csrf保护
    28                 .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
    29                 //5.忽略这些路径的csrf保护以便admin-client注册
    30                 .ignoringAntMatchers(
    31                         adminContextPath + "/instances",
    32                         adminContextPath + "/actuator/**"
    33                 );
    34     }
    35 }

      6、测试

        1)启动Eureka注册中心,启动admin-server、admin-client、admin-security-server

        2)访问admin-security-server地址:http://localhost:9302/ 

          

        3)输入用户名/密码(admin/123456)访问,效果如下:
