无法解析方法＆＃x27; setBasicauth＆＃x27;在＆＃x27; httpheaders＆＃x27;

Question

我的代码无法在“ httpheaders”中解析方法“ setBasicicAuth”。我正在尝试将我的Java代码复制到Android Studio，但面临此问题。我错过了一些进口吗？

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


HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));    // works
headers.setContentType(MediaType.APPLICATION_JSON);                          // works
headers.setBasicAuth(this.authenticationToken);                              // does not work

gradle

// Spring Framework
implementation 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
