springboot之RestTemplate接口封装的示例分享

下文笔者讲述封装RestTemplate接口的示例分享,如下所示

实现思路:只需对RestTemplate方法进行相应的封装即可实现HttpClient的效果

例:

import java.util.Map;import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.TypeReference;public class RestTemplateToInterface {/*** * @param hashMap 请求参数* @param token token验证* @param getOrPost get或者post请求* @param url 请求路径* @return*/public static Map getData(Map hashMap,String token,String getOrPost,String url) {RestTemplate restTemplate = new RestTemplate();//设置请求头，或其他需要需要的HttpHeaders httpHeaders = new HttpHeaders();httpHeaders.add("Content-Type", "application/json; charset=UTF-8");//设置参数;HttpEntity> requestEntity = new HttpEntity>(hashMap, httpHeaders);ResponseEntity resp = null;//执行请求if(getOrPost.equals("get")) {resp = restTemplate.exchange(url, HttpMethod.GET, requestEntity, String.class);} else {resp = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);}//获取返回数据String body = resp.getBody();Map res = JSON.parseObject(body, new TypeReference< Map>() {});return res;}}
