@REST org.springframework.web.client.HttpClientErrorException: 400 Bad Request

[Frank Harper]

When I run my App, I'm getting a HttpClientErrorException: 400 Bad Request for the following line of code.
        Wine sw = mRestApi.getWine( "48854" );

The error message isn't very helpful, so I'm hoping someone can point me in the right direction.

The getWine method generated by AA is:
    @Override
    public WineCom getWine(String id) {
        HashMap<String, Object> urlVariables = new HashMap<String, Object>();
        urlVariables.put("id", id);
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
        HttpEntity<Object> requestEntity = new HttpEntity<Object>(httpHeaders);
        return restTemplate.exchange(rootUrl.concat("http://services.com/catalog?filter=product({id})"), HttpMethod.GET, requestEntity, Wine.class, urlVariables).getBody();
    }

My Wine class is the following:
public class Wine {
    private String id;
    private String name;
    private String url;
    private String appelationId;
    private String appelationName;
    private String regionId;
    private String regionName;
    private String drinkType;
    private String varietalId;
    private String varietalName;   
}

I'm wondering if the mapping might be failing because my POJO doesn't contain all the data returned? Or it might be something else entirely...

unless your rootUrl is "" the concat would probably mess things up for
you. But that's just from reading through the code quickly after some
undeserved Friday beer :).

rootUrl.concat("http://services.com/catalog?filter=product({id})")

should perhaps be more like

rootUrl.concat("/catalog?filter=product({id})")

Thanks, that got me going again! I was completely blind by last night, and couldn't even see the obvious things anymore.

Of course if the error message had contained the actual URL that was being accessed, it would have been obvious to me even in that state.
