spring-cloud-eureka服务发现注册中心及spring-cloud微服务
spring-cloud 使用eureka作为服务注册与发现中心，与zookeeper不同，eureka没有提供可直接运行的压缩文件，需要我们手动搭建eureka服务器。spring-cloud 与dubbo区别参考 https://www.cnblogs.com/aspirant/p/9089146.html
eureka服务器的搭建很简单与一般的spring-boot应用相同，只是启动类需要加上EnableEurekaServer注解并加上相应的配置
下面是我的eureka服务器
首先新建eureka项目

eureka
1.0-SNAPSHOT pom.xml 主要依赖spring-cloud-starter-netflix-eureka-server

application.properties spring-cloud-eureka详细配置参考 https://www.cnblogs.com/chry/p/7992885.html
server.port=8761
#是否注册到eureka-server
eureka.client.register-with-eureka=false
#否从eureka服务器获取注册信息
eureka.client.fetch-registry=false
#在Eureka服务器获取不到集群里对等服务器上的实例时，需要等待的时间，单位为毫秒，默认为1000 * 60 * 5
eureka.server.waitTimeInMsWhenSyncEmpty=0启动类 spring-boot 2.0.0以上需要引入gson我没有引用所以在exclude 加入了GsonAutoConfiguration

@EnableEurekaServer

}
注意EnableEurekaServer注解

可以看到没有 实例注册到eureka上
下面我们新建一个client工程作为服务提供者注册到eureka（本身也是一个消费者这里我只用作提供者）spring-cloud微服务采用rest协议所以每一个微服务都是一个web工程

spring.application.name=provider-client

defaultZone是指定eureka服务器的地址，无论是注册还是发现服务都需要这个地址。spring.application.name是指定进行服务注册时该服务的名称

注意EnableDiscoveryClient注解，只有加了这个注解eureka服务器才会注册此服务
下面新建一个controller作为提供接口

import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ProviderController {
private Environment environment;
@Autowired
public ProviderController(Environment environment){
this.environment = environment;
}
@RequestMapping("/provider")
public String provider(){
return "provider server port:" + environment.getProperty("server.port");
}
}

现在我们需要一个消费者应用来消费这个服务(spring-cloud为服务采用rest协议，所以消费者与提供者之间使用RestTemplate通信)

注意SERVER_NAME为上面client工程application.properties中的spring.application.name
可以看到使用restTemplate只用指定协议+服务名称+对应的路径就可以访问spring-cloud微服务（与直接localhost:8764/provider不同，不用指定端口和host）
