Ich habe hier ein seltsames Problem.
Der folgende Code funktioniert einwandfrei, bis ich den Tomcat-Server auf der Clientseite neu starte. Sobald ich den Tomcat-Server (das Client-Programm befindet sich in der War-Datei) mit der neuesten War-Datei mit demselben Code neu starte, wird der folgende Fehler ausgegeben. Ich benutze JDK 8.
Unten ist der Beispielcode. Über den Browser kann ich eine Antwort von der im folgenden Programm verwendeten URL erhalten. aber nicht in der Lage, die Daten mit Java-Programm oder Postman auch zu bekommen.
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);
}
}
}
Hier ist die Ausnahme:
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
