配置文件 application.properties

# 端口號
server.port=5000

# 服務(wù)名
spring.application.name=eureka-server

# 是否注冊自己
eureka.client.register-with-eureka=false
# 是否需要檢索服務(wù)
eureka.client.fetch-registry=false

啟動類 MainApplication

@EnableEurekaServer //  開啟注冊中心服務(wù)
@SpringBootApplication
public class MainApplication {

    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class, args);
    }

}

啟動服務(wù)

訪問 http://localhost:5000/

顯示上圖，說明服務(wù)注冊中心搭建完成

注冊一個應(yīng)用account到注冊中心

配置文件 application.properties

# 端口號
# 端口號
server.port=8000

# 服務(wù)名
spring.application.name=account

# eureka服務(wù)注冊中心地址
eureka.client.serviceUrl.defaultZone=http://localhost:5000/eureka/

啟動類 MainApplication

@EnableEurekaClient
@SpringBootApplication
@RestController
@RequestMapping
public class MainApplication {

    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class, args);
    }


    @GetMapping("hello")
    public String hello(@RequestParam("name") String name) {
        return "hello " + name;
    }

}

啟動服務(wù)

訪問 http://localhost:5000/

image2.png

圖中可以看出，account服務(wù)已經(jīng)注冊到了eureka-server中

訪問 http://localhost:8000/hello?name=liuxd

account服務(wù)可以正常訪問
