У меня здесь странная проблема.
Приведенный ниже код работает нормально, пока я не перезапущу сервер Tomcat на стороне клиента. Как только я перезапускаю сервер Tomcat (клиентская программа есть в файле war) с последним файлом war того же кода, он выдает следующую ошибку. Я использую JDK 8.
Ниже приведен пример кода. Из браузера я могу получить ответ с URL-адреса, используемого в приведенной ниже программе. но не в состоянии получить данные, используя программу Java или Почтальон также.
package com.example.demo;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;
@Component
public class TestService implements CommandLineRunner{
@Override
public void run(String... args) throws Exception {
download();
}
private void download() {
System.out.println("Started download");
try{
RestTemplate restTemplate = new RestTemplate();
String url = "https://www.nseindia.com/live_market/dynaContent/live_watch/stock_watch/niftyStockWatch.json";
byte[] forObject = restTemplate.getForObject(url, byte [].class);
System.out.println(forObject);
System.out.println("Downloaded");
}catch (Exception e) {
System.out.println("Exception "+ e);
}
}
}
Вот исключение:
org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://www.nseindia.com/live_market/dynaContent/live_watch/stock_watch/niftyStockWatch.json": Connection reset; nested exception is java.net.SocketException: Connection reset
