Guys I’m trying to perform a query in a time forecast API but whenever I will perform the query give me this exception

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: URI is not absolute] with root cause

My control where you are with Resttemplate is like this

        RestTemplate restTemplate = new RestTemplate();

    StringBuilder stringBuilder = new StringBuilder();
    String urlFinal = stringBuilder.append(url).append(cidade).append("&appid=").append(apiKey).toString();

    ResponseEntity<WeatherResponseObject> entity = restTemplate.getForEntity(urlFinal, WeatherResponseObject.class);

    System.out.println(entity.getBody());

    return entity.getBody();

And finally the return of my Weatherresponseobject

public List<BodyWeather> list;
java api spring spring-boot rest

  • as you are having an Illegalargumentexception exception does the following, take the impression of that urlFinal on your console and check if and endpoint is correct.

  • I have performed this test to check if the endpoint was wrong, however it is generated correctly, also I have passed the url directly to check if it was not this

Strange, this error gives the impression that your URL is wrong, but as you said you are not, try using Uricomponentsbuilder. It would look something like this:

UriComponentsBuilder builder = UriComponentsBuilder
                    .fromUriString(openWeatherProperties.getUrl());

builder.queryParam("appid", openWeatherProperties.getAppId());
            
WeatherResponseObject wheater = restTemplate.getForObject(builder.build().toUriString(), WeatherResponseObject.class);
