有没有办法在org.springframework.web.client.RestTemplate中设置用户

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

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

        // 创建HttpHeaders对象
        HttpHeaders headers = new HttpHeaders();

        // 设置用户认证信息
        headers.setBasicAuth("username", "password");

        // 设置Content-Type为application/json
        headers.setContentType(MediaType.APPLICATION_JSON);

        // 创建HttpEntity对象，并将headers设置为请求头
        HttpEntity<String> entity = new HttpEntity<>(headers);

        // 发送GET请求，并获取响应
        ResponseEntity<String> response = restTemplate.exchange("http://example.com/api/resource", HttpMethod.GET, entity, String.class);

        // 处理响应结果
        if (response.getStatusCode().is2xxSuccessful()) {
            String responseBody = response.getBody();
            System.out.println(responseBody);
        } else {
            System.out.println("请求失败");
        }
    }
}
