I'm getting a simple `json` response and wanted to map it as follows to a pojo:

```
ResponseEntity<JsonEntity> response = new RestTemplate().getForEntity(url, JsonEntity.class);

@JsonIgnoreProperties(ignoreUnknown = true)
public class JsonEntity {
    //@JsonProperty getter + setter...
}

```

But I'm just getting the following exception. What might be missing?

> 
> org.springframework.web.client.RestClientException: Could not extract
>  response: no suitable HttpMessageConverter found for response type
>  [class JsonEntity] and content type [application/octet-stream]
>
