Spring Boot RestTemplate - Log the Request and Response

Recently when working on a rest client using the Spring's RestTemplate, I needed to log the request and response as I had no clue what was wrong with my code.

Spring provides the option to write your own Interceptors. For this specific requirement, Spring provides the ClientHttpRequestInterceptor interface. I had to override its intercept method and implement my logic there. Below is the snapshot of my code

public class MyInterceptor implements ClientHttpRequestInterceptor  {
    public ClientHttpResponse intercept(HttpRequest httpRequest, byte[] body, ClientHttpRequestExecution execution)                 throws IOException {
             printRequest(httpRequest, body);
            ClientHttpResponse response = execution.execute(httpRequest, body);
            return response;

    private void printRequest(HttpRequest httpRequest, byte[] body) throws IOException {            
            System.out.println("URI         = "+ httpRequest.getURI());            
            System.out.println("Method      = "+ httpRequest.getMethod());
            System.out.println("Headers     = "+ httpRequest.getHeaders());
            System.out.println("Request body= "+ new String(body, "UTF-8"));

    private void printResponse(ClientHttpResponse response) throws IOException {           
            System.out.println("Status code  = " + response.getStatusCode());
            System.out.println("Status text  = "+ response.getStatusText());
            System.out.println("Headers      = "+ response.getHeaders());
            System.out.println("Response body= "+ StreamUtils.copyToString(response.getBody(), Charset.defaultCharset()));

restTemplate.setInterceptors(Collections.singletonList(new MyInterceptor ()));

Printing the details of request and response help me to figure out what was wrong with my Request call but I was getting the Attempted read from closed stream when processing the Response again in my code. As my issue was resolved, I turned off the interceptor for RestTemplate.


  1. Hello,

    How do you solve this problem: "Attempted read from closed stream". I'm facing the same one.

  2. Response stream is already read while logging it, reading it again throws this exception. I have not explored it myself.
