feign和rabbin整合

一、使用cloud-feign整合
1.1 导入依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>

1.2 编写customer
1.2.1 编写启动类

@SpringBootApplication
@EnableDiscoveryClient
public class CustomerApplication {
    public static void main(String[] args) {
        SpringApplication.run(CustomerApplication.class,args);
    }
}

1.2.2 编写yml

server:
  port: 9012
spring:
  application:
    name: customer
  cloud:
    nacos:
      discovery:
        server-addr: http://162.14.64.72:8848
management:
  endpoints:
    web:
      exposure:
        include: "*"

1.2.3 编写comtroller

@RestController
@RequestMapping(value = "customer")
public class TestCustomerComtroller {
    @Value("${server.port}")
    private String port;
    @GetMapping("/test")
    public String test(){
        System.out.println("customer port:"+port);
        return port;
    }
}

1.3 编写pulisher
1.3.1 编写controller

@RestController
@RequestMapping("publisher")
public class PublisherController {
    @Autowired
    private CostomerFeignClient costomerFeignClient;
    @GetMapping("/test")
    public String test(){
        String test = costomerFeignClient.test();
        return test;
    }
}

1.3.2 编写feignclient

@FeignClient(value = "customer")
public interface CostomerFeignClient {
    @RequestMapping("/customer/test")
    public String test();
}

1.4 测试
