RestTemplate not found-CodePudding

I'm trying to make a RestClient, but I have an error from RestTemplate class and I don't know why.

@Component public class RestClient {

private static final Logger LOGGER = LoggerFactory.getLogger(RestClient.class);

private final RestTemplate restTemplate;

@Autowired
public RestClient(RestTemplate restTemplate) {
    this.restTemplate = restTemplate;
}

public <T> T getForObject(
        final String url,
        final Map<String, String> headerParams,
        final Class<T> expectedResponseType){

    final HttpHeaders headers = new HttpHeaders();
    headers.setAll(headerParams);
    return exchange(url, expectedResponseType, new HttpEntity<>(headers), HttpMethod.GET);
}

private <T> T exchange(
        final String url,
        final Class<T> expectedResponseType,
        final HttpEntity<Object> httpEntity,
        final HttpMethod method) {

    LOGGER.debug("Doing a {} on url {}", method, url);
    return restTemplate.exchange(url, method, httpEntity, expectedResponseType).getBody();
}

}

and the error is this:

APPLICATION FAILED TO START

CodePudding user response：

You have to provide a Bean of type RestTemplate, e.g,

@Bean
RestTemplate restTemplate() {
  return new RestTemplate();
}
