服务端新增引入依赖

            org.springframework.cloud
            spring-cloud-starter-alibaba-nacos-discovery
            0.2.1.RELEASE
        

 

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=192.168.50.31:8848

消费端POM.XML如下，引入ribbon与openfeign支持

            io.springfox
            springfox-swagger-ui
            2.5.0
        
    

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
