一、新建父项目，再加modul

父项目pom.xml

<!--1.管理 SpringBoot的jar包-->
    <!--SpringBoot-->
    <parent>
        <groupId> org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.5.RELEASE</version>
    </parent>
 
    <!--2.管理 SpringCloud的jar包，父项目只管理，不引用-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR3</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
 
    <!--3.这里是所有子项目都可以用的jar包-->
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>
    <modules>
        <module>springcloud-eureka-server</module>
        <module>springcloud-order-server</module>
        <module>springcloud-user-server</module>
        <module>springcloud-user-common</module>
        <module>springcloud-pay-server</module>
        <module>springcloud-zuul-server</module>
    </modules>

 二、eureka

1.pom.xml导入依赖

<dependencies>
        <!--Eureka服务依赖，包含了Eureka客户端包、Springboot-start-web包-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
</dependencies>

2.在resources下建application.yml

server: # Eureka服务端端口号
  port: 1010
 
eureka: # Eureka配置
  instance: # 定义该服务Ip
    hostname: localhost
    # 从上一次收到心跳之后，等待下一次心跳的时间，也就是服务剔除时间，默认90秒
    lease-expiration-duration-in-seconds: 30
    # 发送心跳时间，默认30秒
    lease-renewal-interval-in-seconds: 10
  client: # Eureka客户端配置
    registerWithEureka: false # 该服务不注册到到注册中心
    fetchRegistry: false # 该服务不拉取注册表
    serviceUrl: # 注册中心地址 http://localhost:1001/eureka/
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  server:
    enable-self-preservation: false # 关闭Eureka自我保护机制
      # 自我保护续约百分比，默认是0.85
    renewal-percent-threshold: 0.85

3.在src/main/java下建cn.zyb.EurekaServerApp

@SpringBootApplicatio
