RestTemplate().postForEntity的参数使用及说明

import org.springframework.http.*;
import org.springframework.web.client.RestTemplate;

public class RestTemplateExample {
    public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate();

        // 请求 URL
        String url = "http://example.com/api";

        // 构建请求体
        User user = new User("John", 30); // 自定义 User 类
        HttpEntity<User> request = new HttpEntity<>(user);

        // 发送 POST 请求并获取响应
        ResponseEntity<String> response = restTemplate.postForEntity(url, request, String.class);

        // 获取响应结果
        HttpStatus statusCode = response.getStatusCode();
        HttpHeaders headers = response.getHeaders();
        String body = response.getBody();

        // 处理响应结果
        System.out.println("Status Code: " + statusCode);
        System.out.println("Response Headers: " + headers);
        System.out.println("Response Body: " + body);
    }
}

Map<String, Object> requestMap = new HashMap<>();
  // 发动机型号
requestMap.put("engine_model", "1234");
// 发动机编号
requestMap.put("engine_code", "6789"); 
  // 请求 URL
String url = "http://example.com/api";
 // 调对方接口
ResponseEntity<String> responseEntity = new RestTemplate().postForEntity(url, requestMap , String.class);
Map<String, Object> responseBodyMap = GsonUtil.gsonToMaps(responseEntity.getBody());
 // 对方接口返回值  true传输成功 false  失败
Map<String, Object> result = (Map<String, Object>) responseBodyMap.get("result");
boolean isSuccess = (Boolean) result.get("success");
