注册中心依赖：
<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-dependencies</artifactId>
   <version>${spring-cloud.version}</version>
   <type>pom</type>
   <scope>import</scope>
</dependency>

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
   <version>3.1.2</version>
</dependency>
启动类上加@EnableEurekaServer注解

服务注册依赖：

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency> 
        <groupId>org.springframework.cloud</groupId> 
        <artifactId>spring-cloud-dependencies</artifactId> 
        <version>${spring-cloud.version}</version> 
        <type>pom</type> 
        <scope>import</scope> 
</dependency>
启动类上加@EnableDiscoveryClient注解

服务发现：

@Configuration
public class ConfigBean {
    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

@Autowired

RestTemplate restTemplate;

加了负债均衡的话，url是服务名字，否则是ip地址

url = "http://serviceName/"

restTemplate.getForObject(url,class);

yml配置（注册中心和客户端都要配eureka）

spring:
  application:
    name: 起个名字

eureka:
  instance:
    prefer-ip-address: true
    ip-address: ip地址
  client:
    service-url:
      defaultZone: http://ip地址:端口号/eureka/
server:
  port: 7000
