Get RequestBody and ResponseBody at HandlerInterceptor

Question

Logic I have to implement is logging all requests with body served to DB.

So I decided to use: afterCompletion method of HandlerInterceptor

Answer 1

You can extend RequestBodyAdviceAdapter and implement the method afterBodyRead:

@ControllerAdvice
public MyRequestBodyAdviceAdapter extends RequestBodyAdviceAdapter {

    @Override
    public Object afterBodyRead(Object body, HttpInputMessage inputMessage, MethodParameter parameter,
            Type targetType, Class> converterType) {

        // write body -your input dto- to logs or database or whatever

        return body;
    }

}

The RequestBodyAdvice comes in pre setp the request chain before the HandlerInterceptor. it is exactly after the http request inputstream is converted to your object.
