新建eureka-client模塊

代碼結(jié)構(gòu)如下：

SpringCloudEurekaClientApplication.java

package com.cppba;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@EnableEurekaClient
@RestController
public class SpringCloudEurekaClientApplication {

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

    @Value("${server.port}")
    private String port;

    @RequestMapping("/hi")
    public String sayHi(@RequestParam String name) {
        return "hi " + name + ",i am from port:" + port;
    }
}

application.properties

server.port=8764

eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/

spring.application.name=service-say

到此項目搭建完成

啟動項目

啟動eureka-client之前，我們先啟動上一節(jié)搭建的eureka-server，兩個服務(wù)都啟動好以后铐维，我們訪問注冊中心，可以看到：

說明我們服務(wù)注冊成功慎菲！訪問一下http://127.0.0.1:8764/hi?name=hornet
