在使用Ribbon调用广告投放系统API之前，我们需要先创建2个VO对象，AdPlanVO,AdPlanGetRequestVO.

//数据请求对象
@Data
@NoArgsConstructor
@AllArgsConstructor
public class AdPlanGetRequestVO {private Long userId;private List<Long> planIds;
}----------------------------------//API请求响应结果反序列化对象
@Data
@AllArgsConstructor
@NoArgsConstructor
public class AdPlanVO {private Long planId;private Long userId;private String planName;private Integer planStatus;private Date startDate;private Date endDate;private Date createTime;private Date updateTime;
}

在AdSearchApplication启动类中，添加RestTemplate客户端。

public class AdSearchApplication {.../*** 注册{@link RestTemplate}Bean* @return*/@Bean@LoadBalanced //让RestTemplate在调用服务的时候，可以实现负载均衡RestTemplate restTemplate(){return new RestTemplate();}
}

创建一个controller，来测试调用广告提供系统的API

/*** SearchController for search information controller** @author <a href="mailto:magicianisaac@gmail.com">Isaac.Zhang | 若初</a>*/
@RestController
@Slf4j
@RequestMapping(path = "/search")
public class SearchController {//注入RestTemplateprivate final RestTemplate restTemplate;@Autowiredpublic SearchController(RestTemplate restTemplate) {this.restTemplate = restTemplate;}@GetMapping(path = "/plan/get-ribbon")public CommonResponse<List<AdPlanVO>> getAdPlansUseRibbon(@RequestBody AdPlanGetRequestVO requestVO) {log.info("ad-search::getAdPlansUseRibbon -> {}", JSON.toJSONString(requestVO));return restTemplate.postForEntity("http://mscx-ad-sponsor/ad-sponsor/plan/get", requestVO, CommonResponse.class).getBody();}@GetMapping(path = "/user/get")public CommonResponse getUsers(@Param(value = "username") String username) {log.info("ad-search::getUsers -> {}", JSON.toJSONString(username));CommonResponse commonResponse = restTemplate.getForObject("http://mscx-ad-sponsor/ad-sponsor/user/get?username={username}", CommonResponse.class, username);return commonResponse;}
}
