Spring Boot Admin监控搭建-nacos版本

Spring Boot Admin介绍

Spring Boot Admin 是github上一款用于Spring Boot 的监控管理的开源项目，通过http直接注册或者通过注册中心注册的方式，实现了Spring Boot应用上的一些常见监控项,具体功能点如下:

• 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
• 其他监控点

详细监控项可到githup上去查看

快速搭建

本文是基于nacos注册中心配置实现，在开始前需要安装好nacos服务端。

搭建服务：

1. admin-server 监控服务端
2. admin-client 被监控的客户端

创建Admin-server应用

添加pom依赖：

<properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><maven.deploy.skip>true</maven.deploy.skip><nacos.version>2.2.4.RELEASE</nacos.version><spring-boot.version>2.2.5.RELEASE</spring-boot.version><spring-boot.admin.version>2.2.2</spring-boot.admin.version><spring-boot-starter-actuator.version>2.2.5.RELEASE</spring-boot-starter-actuator.version></properties><dependencies><!--监控服务端 --><dependency><groupId>de.codecentric</groupId><artifactId>spring-boot-admin-starter-server</artifactId><version>${spring-boot.admin.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>${spring-boot.version}</version></dependency><!--nacos注册中心--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>${nacos.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId><version>${spring-boot-starter-actuator.version}</version></dependency></dependencies>

添加配置

server:port:8012spring:application:name: admin-server
  #配置中心cloud:nacos:discovery:server-addr: 127.0.0.1:8848service:  ${spring.application.name}# 暴露监控端点management:endpoints:web:exposure:include:'*'endpoint:health:show-details: always
# 日志      logging:file: /application/applogs/admin.log

启动类增加注解

@EnableAdminServer 注解，开启监控服务端的功能

@EnableAdminServer@SpringBootApplicationpublicclassAdminServerApp{publicstaticvoidmain(String[] args){SpringApplication.run(AdminServerApp.class, args);}}

启动后，我们就可以看到

创建Admin-client应用

添加pom依赖

<properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><maven.deploy.skip>true</maven.deploy.skip><nacos.version>2.2.4.RELEASE</nacos.version><spring-boot.version>2.2.5.RELEASE</spring-boot.version><spring-boot.admin.version>2.3.0</spring-boot.admin.version><spring-boot-starter-actuator.version>2.2.5.RELEASE</spring-boot-starter-actuator.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>${spring-boot.version}</version></dependency><!--nacos注册中心--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>${nacos.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId><version>${spring-boot-starter-actuator.version}</version></dependency></dependencies>

client是通过nacos向admin注册的，所以只需要开启nacos注册服务和actuator监控点的服务就可以了，

配置文件

server:port:8013spring:application:name: admin-client
  #配置中心cloud:nacos:discovery:server-addr: 127.0.0.1:8848service:  ${spring.application.name}# 暴露监控端点management:endpoints:web:exposure:include:'*'endpoint:health:show-details: always

logging:file: /application/applogs/admin.log

启动类

@SpringBootApplicationpublicclassClientApp{publicstaticvoidmain(String[] args){SpringApplication.run(ClientApp.class, args);}}

最普通的一个springboot应用，启动之后

至此，监控应用已经搭建完成。

设置登录信息

admin默认启动时随机生成秘钥进行验证登录的，我们添加spring security 提供登录验证

admin-server添加依赖

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

增加配置文件

server:port:8012spring:application:name: admin-server
  #配置中心cloud:nacos:discovery:server-addr: 127.0.0.1:8848service:  ${spring.application.name}metadata:user.name: admin
          user.password:654321security:user:name: admin
      password:654321# 暴露监控端点management:endpoints:web:exposure:include:'*'endpoint:health:show-details: always

logging:file: /application/applogs/admin.log

metadata 是向nacos注册时携带用户米密码，以防注册时被权限限制无法获取到数据,增加 security 配置，配置用户名 admin，密码654321

添加拦截配置

@ConfigurationpublicclassSecuritySecureConfigextendsWebSecurityConfigurerAdapter{privatefinalString adminContextPath;publicSecuritySecureConfig(AdminServerProperties adminServerProperties){this.adminContextPath = adminServerProperties.getContextPath();}@Overrideprotectedvoidconfigure(HttpSecurity http)throwsException{// 登录成功处理类SavedRequestAwareAuthenticationSuccessHandler successHandler =newSavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter("redirectTo");
        successHandler.setDefaultTargetUrl(adminContextPath +"/");

        http.authorizeRequests()//静态文件允许访问.antMatchers(adminContextPath +"/assets/**").permitAll()//登录页面允许访问.antMatchers(adminContextPath +"/login","/css/**","/js/**","/image/*").permitAll()//其他所有请求需要登录.anyRequest().authenticated().and()//登录页面配置，用于替换security默认页面.formLogin().loginPage(adminContextPath +"/login").successHandler(successHandler).and()//登出页面配置，用于替换security默认页面.logout().logoutUrl(adminContextPath +"/logout").and().httpBasic().and().csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()).ignoringAntMatchers("/instances","/actuator/**");}

然后启动admin-server，输入用户名密码登录
