After many attempts, I'm here to ask if there is a way to log the input JSON request before it is deserialized into a Java Object.
My attempts:
1: I'm able to correctly log the request, before deserialization, but then is giving me "I/O error while reading input message"

}
return stringBuilder.toString();

}

One solution in order to be able to log before the API is invoked and without having exceptions is by using a ControllerAdvice:
4: The request is already deserialized, so in order to log the json as string I have to serialize the request.
Code: RequestBodyControllerAdvice
@Slf4j
@ControllerAdvice
@RequiredArgsConstructor
public class RequestBodyControllerAdvice extends RequestBodyAdviceAdapter {
private final HttpServletRequest httpServletRequest;
@Override
public boolean supports(MethodParameter methodParameter, Type type,
Class<? extends HttpMessageConverter<?>> aClass) {
return true;
}
@Override
public Object afterBodyRead(Object body, HttpInputMessage inputMessage,
MethodParameter parameter, Type targetType,
Class<? extends HttpMessageConverter<?>> converterType) {
String json;
if (body instanceof JsonSerializer object) {
json = object.toJSON();
} else {
try {
json = OBJECT_MAPPER.writeValueAsString(body);
} catch (JsonProcessingException e) {
throw new RuntimeException(e);
}
}
log.info("REQUEST: {}", json);
return super.afterBodyRead(body, inputMessage, parameter, targetType, converterType);
}
private static final ObjectMapper OBJECT_MAPPER = new ObjectMapper();
}

I'm looking for a solution to:
I remember I had the same issue. Basically, the problem is if you consume the input stream you are going to get:
Required request body is missing after reading request since the input stream can only be consumed once.
This filter saves into our own CachedBodyHttpServletRequest to be able to use it for both logging and further processing
@Slf4j
@Component
public class LoggingFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest request,
HttpServletResponse response,
FilterChain filterChain) throws ServletException, IOException {
var cachedRequest = new CachedBodyHttpServletRequest(request);
log.info("PROCESSING REQUEST: " + request.getMethod() + " " + request.getRequestURI()
+ getParameters(request));
filterChain.doFilter(cachedRequest, response);
}
@SneakyThrows
private String getParameters(HttpServletRequest request) {
String body = new String(request.getInputStream().readAllBytes(), StandardCharsets.UTF_8);
return body.isEmpty() ? "" : ", with following body: " + body;
}
}
public class CachedBodyHttpServletRequest extends HttpServletRequestWrapper {
private final byte[] cachedBody;
public CachedBodyHttpServletRequest(HttpServletRequest request) throws IOException {
super(request);
this.cachedBody = StreamUtils.copyToByteArray(request.getInputStream());
}
@Override
public ServletInputStream getInputStream() throws IOException {
return new CachedBodyServletInputStream(this.cachedBody);
}
@Override
public BufferedReader getReader() throws IOException {
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(this.cachedBody);
return new BufferedReader(new InputStreamReader(byteArrayInputStream));
}
}
Relatively straight forward class that saves the inputStream into the byte array and lets you getInputStream multiple times by returning a ServletInputStream implementation of our CachedBodyServletInputStream.
public class CachedBodyServletInputStream extends ServletInputStream {
private final InputStream cachedBodyInputStream;
public CachedBodyServletInputStream(byte[] cachedBody) {
this.cachedBodyInputStream = new ByteArrayInputStream(cachedBody);
}
@Override
public int read() throws IOException {
return cachedBodyInputStream.read();
}
@SneakyThrows
@Override
public boolean isFinished() {
return cachedBodyInputStream.available() == 0;
}
@Override
public boolean isReady() {
return true;
}
@Override
public void setReadListener(ReadListener readListener) {
throw new RuntimeException("Breaks Liskov`s substitution principle :(");
}
}
This class is also relatively easy to follow. It overrides all the necessary methods but also has to override setReadListener for which we have no use in our simple example. While I followed the shortcut of throwing a runtime exception I should warn you that this is a bad style as it breaks the Liskov's Substitution principle... (in such a simple use case as logging negligible, but still)
My solution was based on this article from Baeldung. I posted this solution first because that is what I ended up using in my project, an alternative, and perhaps simpler, solution from this article is to use CommonsRequestLoggingFilter (doesn't work reliably for spring boot < 2.0):
@Bean
CommonsRequestLoggingFilter logFilter() {
CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
filter.setIncludeQueryString(true);
filter.setIncludePayload(true);
filter.setMaxPayloadLength(10000);
filter.setIncludeHeaders(false);
filter.setAfterMessagePrefix("REQUEST DATA : ");
return filter;
}
Remember also to configure logging level to DEBUG:
logging:
level:
org.springframework.web.filter: DEBUG
Notice that the request is logged at the end of the api process.
My last suggesion would have also been the @ControllerAdvice but like you correctly said at that point the request has already been processed and deserialized...
