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
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4 <modelVersion>4.0.0</modelVersion> 5 6 <groupId>com.wunaozai.eureka</groupId> 7 <artifactId>global-service-eureka</artifactId> 8 <version>0.0.1</version> 9 <packaging>jar</packaging> 10 11 <name>global-service-eureka</name> 12 <description>服务注册中心</description> 13 14 <parent> 15 <groupId>org.springframework.boot</groupId> 16 <artifactId>spring-boot-starter-parent</artifactId> 17 <version>2.1.0.RELEASE</version> 18 <relativePath/> <!-- lookup parent from repository --> 19 </parent> 20 21 <properties> 22 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 23 <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 24 <java.version>1.8</java.version> 25 <spring-cloud.version>Greenwich.M2</spring-cloud.version> 26 </properties> 27 28 <dependencies> 29 <dependency> 30 <groupId>org.springframework.cloud</groupId> 31 <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> 32 </dependency> 33 34 <dependency> 35 <groupId>org.springframework.boot</groupId> 36 <artifactId>spring-boot-starter-test</artifactId> 37 <scope>test</scope> 38 </dependency> 39 </dependencies> 40 41 <dependencyManagement> 42 <dependencies> 43 <dependency> 44 <groupId>org.springframework.cloud</groupId> 45 <artifactId>spring-cloud-dependencies</artifactId> 46 <version>${spring-cloud.version}</version> 47 <type>pom</type> 48 <scope>import</scope> 49 </dependency> 50 </dependencies> 51 </dependencyManagement> 52 53 <build> 54 <plugins> 55 <plugin> 56 <groupId>org.springframework.boot</groupId> 57 <artifactId>spring-boot-maven-plugin</artifactId> 58 </plugin> 59 </plugins> 60 </build> 61 62 <repositories> 63 <repository> 64 <id>spring-milestones</id> 65 <name>Spring Milestones</name> 66 <url>https://repo.spring.io/milestone</url> 67 <snapshots> 68 <enabled>false</enabled> 69 </snapshots> 70 </repository> 71 </repositories> 72 73 </project>
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
