Spring MVC 애플리케이션이있다. 문제는 HttpGet을 실행하고 @Component 클래스 내부에서 응답을받을 수 없다는 것입니다. 내 @Component 클래스 함수는 다음과 같습니다.Spring @Component HttpGet execute
private String getSite(String url) throws IOException, InterruptedException {
HttpClient httpclient = HttpClients.createDefault();
HttpGet httpget = new HttpGet(url);
HttpResponse response = httpclient.execute(httpget); // This line causes the problem
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
StringBuilder builder = new StringBuilder();
for (String line = null; (line = reader.readLine()) != null;) {
builder.append(line).append("\n");
}
return builder.toString();
}
콘솔 앱에서 작동하는 것은 완벽합니다.
