RestTemplate ResponseErrorHandler cannot handle 404 FileNotFound #27380

rala72 · 2021-09-10T08:53:14Z

Affects: 2.5.2

I'm making a call to an API which returns 404 with a detailed message in body.
If I do the request, I get something like Caused by: java.io.FileNotFoundException: https://exanple.com/fancy-api/request.

So, I tried to use DefaultResponseErrorHandler but after going through the code with the debugger I noticed that the I/O exception is thrown before the ResponseErrorHandler can handle it.

spring-framework/spring-web/src/main/java/org/springframework/web/client/RestTemplate.java

Lines 765 to 792 in 41ab268

    
           protected <T> T doExecute(URI url, @Nullable HttpMethod method, @Nullable RequestCallback requestCallback, 
        
           		@Nullable ResponseExtractor<T> responseExtractor) throws RestClientException { 
        
           	Assert.notNull(url, "URI is required"); 
        
           	Assert.notNull(method, "HttpMethod is required"); 
        
           	ClientHttpResponse response = null; 
        
           	try { 
        
           		ClientHttpRequest request = createRequest(url, method); 
        
           		if (requestCallback != null) { 
        
           			requestCallback.doWithRequest(request); 
        
           		} 
        
           		response = request.execute(); 
        
           		handleResponse(url, method, response); 
        
           		return (responseExtractor != null ? responseExtractor.extractData(response) : null); 
        
           	} 
        
           	catch (IOException ex) { 
        
           		String resource = url.toString(); 
        
           		String query = url.getRawQuery(); 
        
           		resource = (query != null ? resource.substring(0, resource.indexOf('?')) : resource); 
        
           		throw new ResourceAccessException("I/O error on " + method.name() + 
        
           				" request for \"" + resource + "\": " + ex.getMessage(), ex); 
        
           	} 
        
           	finally { 
        
           		if (response != null) { 
        
           			response.close(); 
        
           		} 
        
           	} 
        
           }

The exception is thrown in 776 but the handler is called in 777.
It would be nice if I can also get the body of I/O Exceptions like FileNotFoundException.

Might also want to refer #15589.

I think it's caused by your LoggingRequestInterceptor calling getInputStream() of url connection, please paste your LoggingRequestInterceptor, I would take a loot at it.

rala72 · 2021-09-13T07:43:35Z

public class LoggingRequestInterceptor implements ClientHttpRequestInterceptor
{
    private static final String MDC_KEY_REQUEST = "request";
    private static final String MDC_KEY_RESPONSE = "response";
    private static final Logger LOG = LoggerFactory.getLogger(LoggingRequestInterceptor.class);

    private final Environment environment;

    public LoggingRequestInterceptor(Environment environment)
    {
        this.environment = environment;
    }

    @Override
    @NonNull
    public ClientHttpResponse intercept(@NonNull HttpRequest request, @NonNull byte[] body, ClientHttpRequestExecution execution)
        throws IOException
    {
        ClientHttpResponse response = execution.execute(request, body);

        if (body.length > 0)
        {
            String requestPayload = new String(body, 0, body.length, StandardCharsets.UTF_8);

            StringBuilder responsePayload = new StringBuilder();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(response.getBody(),
                StandardCharsets.UTF_8));
            String line;
            while ((line = bufferedReader.readLine()) != null)
            {
                responsePayload.append(line);
                responsePayload.append(System.lineSeparator());
            }

            MDC.put(MDC_KEY_REQUEST, requestPayload);
            MDC.put(MDC_KEY_RESPONSE, responsePayload.toString());
            LOG.debug("Executed request to: {}", request.getURI());
            MDC.remove(MDC_KEY_REQUEST);
            MDC.remove(MDC_KEY_RESPONSE);
        }

        return response;
    }
}

Seems correct.
It appears to be an issue with sun.net.www.protocol.http.HttpURLConnection.

You should reuse body to avoid calling response.getBody()

rala72 · 2021-09-13T07:56:18Z

body is the request body but I need the response body.
Calling ClientHttpResponse#getStatusCode before calling ClientHttpResponse#getBody fixed the issue (see second reference above).
