HttpGetHttpRequestBase와의 상속 관계

HttpGet은 HttpRequestBase를 상속합니다.

HttpRequestBase에 대한 시간 초과 구성

RequestConfig를 통해 구성된 RequestConfig 클래스는 다음과 같은 일반적인 요청 매개변수를 정의합니다:

private final int connectionRequestTimeout;
private final int connectTimeout;
private final int socketTimeout;

특정 양식:

final RequestConfig requestConfig = RequestConfig.custom()
 .setConnectionRequestTimeout(1000)
 .setConnectTimeout(1000)
 .setSocketTimeout(1000)
 .build();

구성 방법 1: 요청별 구성

HttpRequestBase의 클래스 변수입니다:

private ProtocolVersion version;
private URI uri;
private RequestConfig config;

특정 양식:

final HttpGet httpGet = new HttpGet(GET_URL);
httpGet.setConfig(requestConfig);

구성 모드 2: 타임아웃 구성으로 HttpClient 만들기

HttpClientBuilder의 클래스 변수입니다:

private RequestConfig defaultRequestConfig;

특정 양식:

CloseableHttpClient httpClient = HttpClients.custom()
 .setDefaultRequestConfig(requestConfig)
 .build()

구성 모드 1:

public void executeAndSetTimeoutWithRequestConfigPerRequest() throws Exception {
 try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
 final RequestConfig requestConfig = RequestConfig.custom()
 .setConnectionRequestTimeout(1000)
 .setConnectTimeout(1000)
 .setSocketTimeout(1000)
 .build();
 final HttpGet httpGet = new HttpGet(GET_URL);
 httpGet.setConfig(requestConfig);
 try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
 EntityUtils.consumeQuietly(response.getEntity());
 }
 }
}

구성 모드 2:

public void executeAndSetTimeoutWithRequestConfig() throws Exception {
 RequestConfig requestConfig = RequestConfig.custom()
 .setConnectionRequestTimeout(1000)
 .setConnectTimeout(1000)
 .setSocketTimeout(1000)
 .build();
 try (CloseableHttpClient httpClient = HttpClients.custom()
 .setDefaultRequestConfig(requestConfig)
 .build()) {
 final HttpGet httpGet = new HttpGet(GET_URL);
 try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
 EntityUtils.consumeQuietly(response.getEntity());
 }
 }
}
