SpringBoot多模块微服务项目搭建

  • 创建Maven父工程
  • 创建Eureka模块
    • pom.xml如下：
    • application.yml如下：
    • 启动类中加入@EnableEurekaServer注解
    • 启动测试

创建Maven父工程

pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><!--继承父模块--><parent><groupId>SpringCloudTest</groupId><artifactId>EurekaTest</artifactId><version>1.0-SNAPSHOT</version></parent><groupId>SpringCloudTest</groupId><artifactId>eurakaservers</artifactId><version>0.0.1-SNAPSHOT</version><name>eurakaservers</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version><spring-cloud.version>Hoxton.SR8</spring-cloud.version></properties><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-server</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>2.3.2.RELEASE</version></plugin></plugins></build></project>

application.yml如下：

server:port: 8080#主机名
eureka:instance:hostname: localhostclient:service-url:defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/   #服务注册地址register-with-eureka: false  fetch-registry: false

启动类中加入@EnableEurekaServer注解

在这里插入图片描述

启动测试

浏览器输入 localhost:8080
测试
出现如图即为成功。
