配置

官方文档：快速开始

引入依赖

---

  <!--openFeign-->
  <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-openfeign</artifactId>
  </dependency>
  <!--负载均衡器（可选）-->
  <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-loadbalancer</artifactId>
  </dependency>

启用注解

---

在启动类上添加@EnableFeignClients。

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