1、步驟

一直下一步到結束

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>

修改pom.xml文件（參考：https://blog.csdn.net/quanqxj/article/details/79877719）

工程的結構

配置文件

spring.application.name=spring-cloud-consumer
server.port=9001
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

啟動工程代碼

package com.demo.springcloudconsumer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class SpringcloudConsumerApplication {

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

feign調用實現

package com.demo.springcloudconsumer.core;

import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

@FeignClient(name="spring-cloud-producer")
public interface HelloRemote {
    @RequestMapping(value = "/hello")
    String hello(@RequestParam(value = "name") String name);
}

web層調用遠程服務

package com.demo.springcloudconsumer.core;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ConsumerController {
    @Autowired
    HelloRemote HelloRemote;

    @RequestMapping("/hello/{name}")
    public String index(@PathVariable("name") String name) {
        return HelloRemote.hello(name);
    }
}

在IDEA上使用springcloud構建單節點的服務消費者
