物联网架构成长之路(30)-Spring Boot Admin微服务WebUI监控

0. 前言

　　一个完整的微服务解决方案包含了许多微服务，基于我们需要观察各个微服务的运行状态，因此Spring Boot 生态提供了Spring Boot Admin 这个组件来实现微服务管理WEB UI。但是整体的注册中心还是基于Eureka，只是WebUI是用这个Spring Boot Admin 来显示而已。具体的结构如下所示

1. Eureka服务

　　这个没什么好说的，按照创建一个微服务的流程，通过 Spring Starter 工具，自动生成一个Eureka微服务。主要就是配置Application.java application.yml pom.xml 这三个文件。
　　pom.xml

　　application.yml 这里我配置两份，一份EUREKA1:8761 一份EUREKA:8762

 server:

   port: 8761

 spring:

   application:

     name: EUREKA服务注册中心

 management:

   endpoints:

     web:

       exposure:

         include:

         - "*"

   endpoint:

     health:

       show-details: ALWAYS

 eureka:

   client:

 #    register-with-eureka: false

 #    fetch-registry: false

     service-url:

       defaultZone: http://EUREKA1:8761/eureka/,http://EUREKA2:8762/eureka/

   instance:

     hostname: EUREKA1

　　Application.java

 package com.wunaozai.eureka;

 import org.springframework.boot.SpringApplication;

 import org.springframework.boot.autoconfigure.SpringBootApplication;

 import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

 @EnableEurekaServer

 @SpringBootApplication

 public class GlobalServiceEurekaApplication {

     public static void main(String[] args) {

         SpringApplication.run(GlobalServiceEurekaApplication.class, args);

     }

 }

2. Spring Boot Admin 服务

　　默认是不需要帐号密码登录的，我这里配置一下spring-boot-starter-security 增加帐号密码登录

                 .httpBasic().and().csrf().disable();

         }

     }

 }

3. Spring Boot Client 服务(配置到Eureka服务)
　　这里就配置Eureka Client 即可
　　pom.xml

 #        url:

 #        - "http://127.0.0.1:8788"

 #        password: 'password'

   application:

     name: 子业务服务器

   endpoint:

 #  client:

 #    fetch-registry: false

 #    register-with-eureka: false

     service-url:

       defaultZone: ${EUREKA_SERVICE_URL:http://172.16.23.241:8761}/eureka/

　　Application.java

 package com.wunaozai.client.demo;

 import org.springframework.boot.SpringApplication;

 import org.springframework.boot.autoconfigure.SpringBootApplication;

 import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

 @EnableEurekaClient

 @SpringBootApplication

 public class SpringCloudClientDemoApplication {

     public static void main(String[] args) {

         System.out.println("ok");

         SpringApplication.run(SpringCloudClientDemoApplication.class, args);

     }

 }

4. Spring Boot Client 服务(直接配置Admin地址)
　　如果不想通过Eureka，只是用Spring Boot Admin，可以只配置Admin的地址来实现。通过在application.yml 配置

 spring:

   boot:

     admin:

       client:

         url:

         - "http://127.0.0.1:8788"

         username: 'user'

         password: 'password'

5. 举个例子(基于docker-compose)

　　使用mvn package 把以上3个微服务打包成Docker镜像
　　Dockerfile 文件

 FROM java:8

 VOLUME /tmp

 ADD spring-cloud-admin-demo-0.0.1.jar app.jar

 RUN bash -c 'touch /app.jar'

 EXPOSE 8788

 ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app.jar"]

　　Build 构建镜像

 docker build -t wunaozai/eureka:0.0.1 -f Dockerfile .

　　docker-compose.yml 文件

 version: '3'

 services:

     EUREKA1:

         image: eureka:1

         ports:

             - 8761:8761

     EUREKA2:

         image: eureka:2

         ports:

             - 8762:8762

     ADMIN:

         image: admin:1

         ports:

             - 8788:8788

     client-1:

         image: client:1

         ports:

             - 18881:18888

     client-2:

         image: client:1

         ports:

             - 18882:18888

     client-3:

         image: client:1

         ports:

             - 18883:18888

     client-4:

         image: client:1

         ports:

             - 18884:18888

     client-5:

         image: client:1

         ports:

             - 18885:18888

     client-6:

         image: client:1

         ports:

             - 18886:18888

     client-7:

         image: client:1

         ports:

             - 18887:18888

     client-8:

         image: client:1

         ports:

             - 18888:18888

　　日志界面

　　WeaveScope 界面

　　Eureka 界面

　　Spring Boot Admin 界面

　　如果出现这个问题，请升级到最新的浏览器(Chrome) 一开始用Chrome 59,不行，升级到Chrome 71 才可以。
