利用RestTemplate进行http调用

在对接API的时候，会涉及调用第三方的服务，这时候可以利用RestTemplate进行调用，下面给大家展示一个简单的调用demo。

 package com.tanlu.user.api.controller.XJH;

 import com.alibaba.fastjson.JSON;
 import com.tanlu.user.common.ResponseData;
 import com.tanlu.user.common.XJH.Dto.XjhPushDto;
 import com.tanlu.user.common.request.UploadRequest;
 import com.tanlu.user.service.XJHPushService;
 import org.slf4j.Logger;
 import org.slf4j.LoggerFactory;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.web.bind.annotation.RequestBody;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.RequestMethod;
 import org.springframework.web.bind.annotation.RestController;
 import java.io.IOException;

 @RestController
 @RequestMapping(value = "/push")
 public class XJHPushController {
     private static Logger logger = LoggerFactory.getLogger(XJHPushController.class);

     @Autowired
     private XJHPushService xjhPushService;

     /**
      * xjh二推
      * @param dto
      * @return
      */
     @RequestMapping(value = "/xjh/secondPush", method = RequestMethod.POST, produces = "application/json")
     public ResponseData secondPush(@RequestBody XjhPushDto dto){
         logger.info("XJH二推请求参数:"+ JSON.toJSON(dto));
         ResponseData responseData = xjhPushService.secondPushData(dto);
         return responseData;
     }

 }

XJHPushService 接口代码：
  public interface XJHPushService {   ResponseData secondPushData(XjhPushDto dto); }
