implementation('org.springframework.boot:spring-boot-starter-web')
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; @Configuration public 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; } }
“JuHe”,然后包里创建一个新的类:JuheResult 【Art+insert】选择CsonFormat
package com.qiubao.school.api.common; public interface Constants { String JUHE_KEY = "e80611926aa6321048bde9ea73d11190"; }
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; } }
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。
