与Spring RestTemplate中的jQuery.ajax dataType raw等效的是什么

import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.web.client.RestTemplate;

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

        // 设置请求头
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);

        // 设置请求体
        String requestBody = "{\"key\":\"value\"}";
        HttpEntity<String> requestEntity = new HttpEntity<>(requestBody, headers);

        // 发送请求并接收响应
        ResponseEntity<String> responseEntity = restTemplate.exchange("http://example.com/api", HttpMethod.POST, requestEntity, String.class);

        // 获取原始的响应数据
        String rawResponse = responseEntity.getBody();
        System.out.println(rawResponse);
    }
}
