How to get responseBody from Java Exception

Question

While calling the REST service, Its giving HttpClientErrorException, I'm able to retrieve status code and error message, but how can I get responseBody ?

I'm trying the bellow code, but unable to typecast to HttpResponse.

catch(HttpClientErrorException e) {  
   // I am trying to typecast to HttpResponse, but its throwing error
     HttpResponse response = (HttpResponse) e;
     String msg = response.getEntity().getContent().toString(); 
}

What am I doing wrong ? Can anyone please suggest?

Answer 1

HttpClientErrorException extends RestClientResponseException which contains the method getResponseBodyAsString().

So it's a mistake to cast it to HttpResponse, in fact HttpClientErrorException doesn't extend HttpResponse

Simply do this

catch(HttpClientErrorException e){  
     String body = e.getResponseBodyAsString();
}
