**服务提供端**

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**配置文件**

**application.yml**

spring:
      application:
        name: hello-service
      cloud:
        consul:
          host: 192.168.57.21
          port: 8500

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**controller 层**

**HelloController**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(){
            return "hello world";
        }
    }

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**消费端**

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**配置文件**

**application.yml**

spring:
      application:
        name: ribbon-consumer
      cloud:
        consul:
          host: 192.168.57.21
          port: 8500

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

@Configuration
    public class WebConfig {
    
        @Bean
        @LoadBalanced  
        public RestTemplate initRestTemplate(){
            return new RestTemplate();
        }
