建立一個maven工程引入以下依賴

建立啟動類

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.openfeign.EnableFeignClients;


//@EnableDiscoveryClient :啟用服務註冊與發現
//@EnableFeignClients：啟用feign進行遠端呼叫

@EnableDiscoveryClient
@EnableFeignClients
@EnableEurekaClient
@SpringBootApplication
public class SpringCloudClientApplication {

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

 

建立一個實體類方便測試用

public class User {
    private String id;
    private String name;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + "]";
	}
    
 

建立一個測試方法

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestClass {
	// 獲取遠端配置檔案的值
	@Value("${test.name}")
	private String name;

	// 獲取遠端配置檔案的值
	@RequestMapping("/testPro")
	public String testproper() {
		return name;
	}

//對外暴露介面，通過微服務或者介面呼叫
	@RequestMapping("/client1")
	public User testUser(@RequestBody User user) {
		System.out.println("client接收引數："+user);
		return user;
	}

testproper方法是為了驗證遠端是否能正確讀取配置檔案，testUser方法是為了測試微服務間呼叫寫的

接下來用postman測試下

先試下配置檔案讀取

沒問題
