1.2 application.yml文件

1.1.1 application.yml文件

代码：

# 服务注册中心 (单节点)
server:
port: 8761
eureka:
instance:
hostname: localhost
client:
fetch-registry: false # 表示是否从Eureka Server获取注册信息,默认为true.因为这是一个单点的Eureka Server,不需要同步其他的Eureka Server节点的数据,这里设置为false
register-with-eureka: false # 表示是否将自己注册到Eureka Server,默认为true.由于当前应用就是Eureka Server,故而设置为false.
service-url:
# 设置与Eureka Server的地址,查询服务和注册服务都需要依赖这个地址.默认是http://localhost:8761/eureka/;多个地址可使用','风格.
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

1.3 启动文件

1.1.1 EurekaServerApplication文件

代码：
(备注：记得添加注解@EnableEurekaServer)

package com.example.eurekaserver;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}

运行main文件，链接是：http://localhost:8761/

2. client 端：EurekaProducer 服务生产者

代码：
(备注：记得添加注解@EnableDiscoveryClient)

package com.example.eurekaclient;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@EnableDiscoveryClient
@RestController
public class EurekaClientApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaClientApplication.class, args);
}
@RequestMapping("sayHello")
public String sayHello(String param){
return "Hello"+param;
}
}
