SpringBoot-RestTemplate如何实现调用第三方API

目录1.在build.grdle加入依赖2.在config包下创建一个RestTemlateConfig3.在model包下创建一个新的包4.Constans类下将调用接口的AppKey值宏定义5.在controller包下创建一个6.用Postman调用接口，验证是否成功1.在build.grdle加入依赖

implementation(’org.springframework.boot:spring-boot-starter-web’)2.在config包下创建一个RestTemlateConfig

配置好相关信息

package com.qiubao.school.api.config; import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.http.client.ClientHttpRequestFactory;import org.springframework.http.client.SimpleClientHttpRequestFactory;import org.springframework.web.client.RestTemplate; @Configurationpublic class RestTemplateConfig { @Bean public RestTemplate restTemplate(ClientHttpRequestFactory factory){return new RestTemplate(factory); } @Bean public ClientHttpRequestFactory simpleClientHttpRequestFactory(){SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();factory.setConnectTimeout(15000);factory.setReadTimeout(5000);return factory; }}3.在model包下创建一个新的包

“JuHe”，然后包里创建一个新的类：JuheResult 【Art+insert】选择CsonFormat

4.Constans类下将调用接口的AppKey值宏定义

package com.qiubao.school.api.common; public interface Constants { String JUHE_KEY = 'e80611926aa6321048bde9ea73d11190';}5.在controller包下创建一个

新的类SpringRestTemplateController（调用第三方的API，浏览器模拟get请求，postman模拟post请求）

package com.qiubao.school.api.controller; import com.alibaba.fastjson.JSONObject;import com.qiubao.school.api.common.Constants;import com.qiubao.school.api.model.Article;import com.qiubao.school.api.model.juhe.JuheResult;import org.apache.commons.lang3.StringUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.*;import org.springframework.web.client.RestTemplate; import java.util.ArrayList;import java.util.List; @RestController@RequestMapping('news')public class SpringRestTemplateController { @Autowired private RestTemplate restTemplate; /***********HTTP GET method*************/ @GetMapping('/testGetApi') public JuheResult getJson( @RequestParam(value = 'type', required = false) String type ){type = StringUtils.isEmpty(type)?'top':type;//定义为可以为空// 将调用接口的Key值宏定义一个名字（Constants类下）String url='http://v.juhe.cn/toutiao/index?type='+type+'&key=' + Constants.JUHE_KEY;//将Jason格式转换为对象（增强可读性、易于后期数据的更改和增删）JuheResult result = restTemplate.getForObject(url, JuheResult.class);return result; }//将调用的Api的Jason数据格式修改为需要的Jason数据格式[用到JuheResult方法] private List<Article> convertJuhe2Article(JuheResult result) {List<Article> articles = new ArrayList<>();for (JuheResult.ResultBean.DataBean dataBean: result.getResult().getData()) { Article article = new Article(); article.setUniquekey(dataBean.getUniquekey()); article.setTitle(dataBean.getTitle()); article.setAuthor_name(dataBean.getAuthor_name()); article.setCreateDate(dataBean.getDate()); article.setContent(dataBean.getUrl()); article.setThumbnail_pic_s(dataBean.getThumbnail_pic_s()); article.setThumbnail_pic_s02(dataBean.getThumbnail_pic_s02()); article.setThumbnail_pic_s03(dataBean.getThumbnail_pic_s03()); article.setCategory(dataBean.getCategory()); article.getCommentCount(); article.getLikeCount(); articles.add(article);}return articles; } }6.用Postman调用接口，验证是否成功

以上为个人经验，希望能给大家一个参考，也希望大家多多支持好吧啦网。
