最近需要搭建个注册中心，其中遇到几个问题记录一下：
首先再idea创建maven项目，接着
1.引入eureka依赖

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>2.1.2.RELEASE</version>
</dependency>

2.增加启动类

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


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

3.增加配置文件application.yml

<?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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>eureka</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>2.2.3.RELEASE</version>
        </dependency>
    </dependencies>
</project>

依赖大功告成了就要，启动报错如下

怀疑是版本问题更换版本,

<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
<version>2.1.2.RELEASE</version>

启动，报错，看样子是缺少了com.google.code.gson包，引入

<dependency>
	<groupId>com.google.code.gson</groupId>
	<artifactId>gson</artifactId>
	<version>2.6</version>
</dependency>

大功告成，访问localhost:8100
