Making HTTP GET Requests with Query Parameters in Spring Boot

To make an HTTP GET request in Spring Boot, you can use the RestTemplate class provided by the Spring Framework. Here's a an example:


    RestTemplate restTemplate = new RestTemplate();
		
	String url = "https://example.com/api/test";

	UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url)
		.queryParam("param1", "value1")
		.queryParam("param2", "value2");
		
	HttpHeaders headers = new HttpHeaders();
	headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
	HttpEntity<String> httpEntity = new HttpEntity<>(headers);

	ResponseEntity<MyResponse> response = restTemplate.exchange(builder.toUriString(), HttpMethod.GET,
		httpEntity, MyResponse.class);

	if(response.getStatusCode().is2xxSuccessful()) {
		//success
		MyResponse myResponse = response.getBody();

	} else {
		//fail
	}

    

In this example, we are using the exchange method of RestTemplate to send a GET request to the specified URL with the query parameters. The method returns a ResponseEntity object, which contains the response status code, headers, and body.
