Spring Rest Template Url contains complex query

I want to call a web service which takes in url a query parametre. This is the query :

{PK} IN({{Select {o.name}  from {Student! as o} where {o.name} IN ({{Select {s.pk} 
 from {School as s} where {s.code}="school"}})}})

I encode the query using this

And i put the encoded query in web service url : http://host?query=query_above_encoded.

So when a do this (call the web service using resttemplate):

ResponseEntity<Model> response = restTemplate.exchange(
                    url, HttpMethod.GET, request, Model.class);

I get this exception :

org.springframework.web.client.HttpServerErrorException: 500 Erreur Interne de Servlet

But when I call the same url using a rest client app (as Postman) a get the response.

Does anyone have any ideas?

Solution

  • The solution is to use URI JAVA object after encoding the url:

    ResponseEntity<Model> response = restTemplate.exchange(
                    new URI(encodedUrl), HttpMethod.GET, request, Model.class);

    Hope this help someone else.
