Microservice construction_eureka registration center

1. Project construction

Create the parent project
pom.xml file

1. The packaging method ispom
2. Delete srcfolder
3. Add SpringBoot parent project
4. Add the version of SpringCloud
5. Can be added to skip the test when packaging

<packaging>pom</packaging>
<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
<!--        换成2.3.3版本 eureka会启动失败-->
<!--        <version>2.3.3.RELEASE</version>-->
    </parent>


 <!--springcloud的版本控制-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <!--打包的时候跳过测试-->
        <skipTests>true</skipTests>
    </properties>

Second, create Eureka module

Create a submodule under the parent project

pom.xml file

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>***</artifactId>
        <groupId>***</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>******</artifactId>

    <!--eureka的服务端 注册中心-->

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>

</project>

application.yml configuration file

server:
  port: 7001
eureka:
  instance:
    hostname: 127.0.0.1
  client:
    register-with-eureka: false   #是否将自己注册到eureka中
    fetch-registry: false         #是否从eureka中获取信息
    service-url:
      defaultZone: http://${
    
    eureka.instance.hostname}:${
    
    server.port}/eureka/
spring:
  application:
    name: eureka

Main start class

package com.mychanggou.goods;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * @author ：LiuShihao
 * @date ：Created in 2020/8/11 3:36 下午
 * @desc ：注册中心启动类
 */
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
    
    
    public static void main(String[] args) {
    
    
        SpringApplication.run(EurekaApplication.class);
    }
}

Three, other modules

1. Add'in the application.yml of each service

eureka:
  client:
    service-url:
      defaultZone: http://localhost:6868/eureka

2. Add eureka client dependency to pom.xml file

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

3. Add @EnableEurekaClientannotations to the main startup class of each service

Start the eureka microservice and visit it in the browser.
