Eu tenho um problema estranho aqui.
O código abaixo está funcionando bem até eu reiniciar o servidor tomcat no lado do cliente. Depois de reiniciar o servidor tomcat (o programa cliente existe no arquivo war) com o arquivo war mais recente do mesmo código, ele gera o erro abaixo. Estou usando o JDK 8.
Abaixo está o código de exemplo. No navegador, posso obter uma resposta do URL usado no programa abaixo. mas não é possível obter os dados usando o programa java ou o Postman também.
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);
}
}
}
Aqui está a exceção levantada:
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
