SpringBoot结合Eureka，配置服务端

场景：为了对单一项目进行拆分，需要模块相互远程调用，负载均衡和限流，进而引入eureka

难点：1.springboot和springcloud版本对应关系

           2.父子项目maven关系梳理

完成代码：

1.父项目pom文件  creativediary：pom.xml添加springcloud依赖

           
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>    

    <properties>
        <spring-cloud.version>Finchley.SR2</spring-cloud.version>
    </properties>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

我的spring-boot-starter-parent版本是2.0.3.RELEASE，对应版本是 Finchley

可查阅官网Spring Cloud

2.子项目pom文件 eurekaServer： pom.xml添加依赖

   
    <parent>
        <artifactId>creativediary</artifactId>
        <groupId>org.mai</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>


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

3.子项目添加启动类，需要添加@EnableEurekaServer

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
    public static void main(String[] args){
        SpringApplication.run(EurekaApplication.class, args);
    }
}

4.默认情况下，Eureka 服务器将自身注册到发现中，需要去除这点

server:
  port: 8761
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
