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

 1 server:
 2   port: 8761
 3
 4 spring:
 5   application:
 6     name: EUREKA服务注册中心
 7
 8 management:
 9   endpoints:
10     web:
11       exposure:
12         include:
13         - "*"
14   endpoint:
15     health:
16       show-details: ALWAYS
17
18 eureka:
19   client:
20 #    register-with-eureka: false
21 #    fetch-registry: false
22     service-url:
23       defaultZone: http://EUREKA1:8761/eureka/,http://EUREKA2:8762/eureka/
24   instance:
25     hostname: EUREKA1

　　Application.java

 1 package com.wunaozai.eureka;
 2
 3 import org.springframework.boot.SpringApplication;
 4 import org.springframework.boot.autoconfigure.SpringBootApplication;
 5 import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
 6
 7 @EnableEurekaServer
 8 @SpringBootApplication
 9 public class GlobalServiceEurekaApplication {
10
11     public static void main(String[] args) {
12         SpringApplication.run(GlobalServiceEurekaApplication.class, args);
13     }
14 }

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

13         SpringApplication.run(SpringCloudClientDemoApplication.class, args);
14     }
15
16 }

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

1 spring:
2   boot:
3     admin:
4       client:
5         url:
6         - "http://127.0.0.1:8788"
7         username: ‘user‘
8         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

1 FROM java:8
2 VOLUME /tmp
3
4 ADD spring-cloud-admin-demo-0.0.1.jar app.jar
5 RUN bash -c ‘touch /app.jar‘
6
7 EXPOSE 8788
8
9 ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app.jar"]

　　Build 构建镜像

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

　　docker-compose.yml 文件

 1 version: ‘3‘
 2
 3 services:
 4     EUREKA1:

0.前言 一开始学的之后,是想一步到位直接上Kubernetes(K8s)的,后面没想到,好像有点复杂,有些概念不是很懂.因此学习东西还是要循序渐进,慢慢来.先了解单机编排技术Docker Compose,了解一些技术细节及原理后,在入手K8s.还是不能一口吃成胖子,要多吃几口才可以.而且目前公司都是一些小项目,能用得上DockerCompose已经很不错了,还想要上K8s,估计是不现实的. 1. 安装 可以通过运行下面命令进行安装, 1 curl -L https://github.com/d

物联网架构成长之路(56)-SpringCloudGateway+JWT实现网关鉴权

0. 前言 结合前面两篇博客,前面博客实现了Gateway网关的路由功能.此时,如果每个微服务都需要一套帐号认证体系就没有必要了.可以在网关处进行权限认证.然后转发请求到后端服务.这样后面的微服务就可以直接调用,而不需要每个都单独一套鉴权体系.参考了Oauth2和JWT,发现基于微服务,使用JWT会更方便一些,所以准备集成JWT作为微服务架构的认证方式. [https://www.cnblogs.com/wunaozai/p/12512753.html] 物联网架构成长之路(54)-基于Naco

使用Spring Boot创建微服务

过去几年以来,"微服务架构"的概念已经在软件开发领域获得了一个稳定的基础.作为"面向服务架构"(SOA)的一个继任者,微服务同样也可以被归类为"分布式系统"这一类,并且进一步发扬了SOA中的许多概念与实践.不过,它们在不同之处在于每个单一服务所应承担的责任范围.在SOA中,每个服务将负责处理广范围的功能与数据领域,而微服务的一种通用指南则认为,它所负责的部分是管理一个单独的数据领域,以及围绕着该领域的相关功能.使用分布式系统方式的目的是将整体性的
