SpringBoot-RestTemplate如何实现调⽤第三⽅API ⽬录
1.在dle加⼊依赖
2.在config包下创建⼀个RestTemlateConfig
3.在model包下创建⼀个新的包
spring framework jar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dle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.fig;
import t.annotation.Bean;
import t.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;
}
}
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.apimon;
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.ller;
import com.alibaba.fastjson.JSONObject;
import com.qiubao.school.apimon.Constants;
import com.qiubao.del.Article;
import com.qiubao.del.juhe.JuheResult;
import org.apachemons.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="v.juhe/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 = ForObject(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:
Article article = new Article();
article.Uniquekey());
article.Title());
article.setAuthor_Author_name());
article.Date());
article.Url());
article.setThumbnail_pic_Thumbnail_pic_s());
article.setThumbnail_pic_Thumbnail_pic_s02());
article.setThumbnail_pic_Thumbnail_pic_s03());
article.Category());
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。
