Spring-cloud-eureka使用feign调用服务接口的具体方法，供大家参考，具体内容如下

基于spring-boot 2.0以上版本完成的微服务架构

pom.xml

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.5.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
  </parent>

feignClient

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/*
 * @version 1.0 created by carolon 2018/9/25 17:18
 */
@FeignClient(value = "服务名")
public interface FeignClient {

  @RequestMapping(method = RequestMethod.POST, value = "接口地址")
  String sendDebugInfo(Object debugInfo);

}

finally

直接在需要的地方注入该client然后调用即可

@Autowired
private FeignService feignService;
