"message": "I/O error on GET request for \"http://localhost:8080/products\": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect",
"path": "/template/getprodgsspringboot"

First spring boot Application : Rest controller

@RequestMapping("/template/getprodgsspringboot")
public String getProductList() {
    HttpHeaders headers=new HttpHeaders();
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    HttpEntity<String> http=new HttpEntity<>(headers);
    return resttemplate.exchange("http://localhost:8080/products",HttpMethod.GET,http,String.class).getBody();

Second Spring boot Application :Rest controller

@RequestMapping("/products")
public ResponseEntity<Object> getMethod(){
    System.out.println("My GET http method");

Please use the below resttemplate and give a try. It should work

ResponseEntity result = restTemplate.exchange(" http://localhost:8080/products ", HttpMethod.GET, http, String.class);
