服务端新增引入依赖

<dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>

            <version>0.2..RELEASE</version>

        </dependency>

启动类开启服务注册支持

@EnableSwagger2

@SpringBootApplication

@EnableDiscoveryClient

public class Application {

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);

    }

}

增加服务注册地址  application.properties

spring.cloud.nacos.discovery.server-addr=192.168.50.31:

消费端POM.XML如下，引入ribbon与openfeign支持

创建服务引用对象，利用FeignClient

package example.dockertest.example.dockertest.service;

import org.springframework.cloud.openfeign.FeignClient;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

@FeignClient(value = "service-provider")

public interface ICustomerService {

    @RequestMapping(value = "/config/get", method = RequestMethod.GET)

    @ResponseBody

    String get();

}

调用服务方法

@RestController

@RequestMapping("/configConsumer")

public class ConfigController {

    @Autowired

    private ICustomerService customerService;

    @RequestMapping(value = "/get", method = RequestMethod.GET)

    @ResponseBody

    public String get() {

        return customerService.get();

    }

}

提供服务发现

@EnableSwagger2

@SpringBootApplication

@EnableDiscoveryClient

@EnableFeignClients

public class Application {

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);

    }

}

启动测试是否能够调用
