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）

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服务器之家。
