httpComponts(mime)에서를 5버전으로 migration하는 과정에서 발생되는 소스코드 수정부분에 대한 내역

# builder 상세정보

- maven(pom.xml) [ 4 -> 5 ]

# version 4 <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpmime --> <dependency>     <groupId>org.apache.httpcomponents</groupId>     <artifactId>httpmime</artifactId>     <version>4.5.14</version> </dependency> # version 5 <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents.client5/httpclient5 --> <dependency>     <groupId>org.apache.httpcomponents.client5</groupId>     <artifactId>httpclient5</artifactId>     <version>5.3.1</version> </dependency>

- gradle(build.gradle) [ 4 -> 5]

# version 4 // https://mvnrepository.com/artifact/org.apache.httpcomponents/httpmime implementation 'org.apache.httpcomponents:httpmime:4.5.14' # version 5 // https://mvnrepository.com/artifact/org.apache.httpcomponents.client5/httpclient5 implementation 'org.apache.httpcomponents.client5:httpclient5:5.3.1'

 

# java source code sample ( version 4 )

URI uri = new URI(url); HttpGet httpGet = new HttpGet(uri); RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(60000) .setSocketTimeout(100000).build(); CloseableHttpClient httpClient = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).build(); HttpResponse response = httpClient.execute(httpGet); String reponseText = EntityUtils.toString(response.getEntity());

 

# java source code sample ( version 5 )

- 5버전에서는 execute 관련 deprecated 된 사항이 많아 사용방식이 많이 변경

- syso는 logback이나 log4j로 변경하도록.

# 방식 1

String url = "http://example.com"; URI uri = new URI(url); HttpGet httpGet = new HttpGet(uri); RequestConfig requestConfig = RequestConfig.custom() .setConnectTimeout(Timeout.ofSeconds(6)) .setResponseTimeout(Timeout.ofSeconds(10)) .build(); try (CloseableHttpClient httpClient = HttpClients.custom() .setDefaultRequestConfig(requestConfig) .build()) {   ResponseHandler<String> responseHandler = response -> {     int status = response.getCode();     if (status >= 200 && status < 300) {       HttpEntity entity = response.getEntity();       return entity != null ? EntityUtils.toString(entity) : null;     } else {       throw new ClientProtocolException("Unexpected response status: " + status);     }   };   String responseText = httpClient.execute(httpGet, responseHandler);   System.out.println(responseText); }

# 방식 2

String url = "http://example.com"; URI uri = new URI(url); HttpGet httpGet = new HttpGet(uri); RequestConfig requestConfig = RequestConfig.custom().setConnectionRequestTimeout(Timeout.ofSeconds(6)) .setResponseTimeout(Timeout.ofSeconds(10)).build(); httpGet.setConfig(requestConfig); String reponseText = ""; try (CloseableHttpClient httpClient = HttpClients.custom() .setDefaultRequestConfig(requestConfig) .build()) {   reponseText = httpClient.execute(httpGet, response -> {     int status = response.getCode();     if (status >= 200 && status < 300) {       return EntityUtils.toString(response.getEntity());     } else {       throw new HttpResponseExceptionException(status, "Unexpected response status: " + status);     }   }); } catch (IOException e) {   System.out.println(e.getMessage()); } System.out.println(reponseText);
