Question

Okay, I have a class NamedSystems, that has as its only field a Set of NamedSystem.

I have a method to find NamedSystems by certain criteria. That\'s not really imp

Or you could extend RestTemplate and override doExecute(..) and check the response body.

For example here is what I implemented and works for us:

@Override
protected  T doExecute(final URI url, final HttpMethod method, final RequestCallback requestCallback, final ResponseExtractor responseExtractor)
        throws RestClientException
{
    Assert.notNull(url, "'url' must not be null");
    Assert.notNull(method, "'method' must not be null");
    ClientHttpResponse response = null;
    try
    {
        final ClientHttpRequest request = createRequest(url, method);
        if (requestCallback != null)
        {
            requestCallback.doWithRequest(request);
        }
        response = request.execute();
        if (!getErrorHandler().hasError(response))
        {
            logResponseStatus(method, url, response);
        }
        else
        {
            handleResponseError(method, url, response);
        }
        if ((response.getBody() == null) || (responseExtractor == null))
        {
            return null;
        }
        return responseExtractor.extractData(response);
    }
    catch (final IOException ex)
    {
        throw new ResourceAccessException("I/O error: " + ex.getMessage(), ex);
    }
    finally
    {
        if (response != null)
        {
            response.close();
        }
    }
}
